High Pressure Fuel Lines


(1) High pressure line(2) High pressure line

(3) High pressure line(4) High pressure line

(5) High pressure fuel manifold (rail)(6) High pressure line

The high pressure fuel lines are the fuel lines thatare between the high pressure fuel pump and thehigh pressure fuel manifold and the fuel lines that arebetween the fuel manifold and cylinder head. Thesefuel lines are different from fuel lines on other fuelsystems.

This is because of the following differences:

• The high pressure fuel lines are constantly chargedwith high pressure.

• The internal pressures of the high pressure fuellines are higher than other types of fuel system.

• The high pressure fuel lines are formed to shapeand then strengthened by a special process.

Do not step on the high pressure fuel lines. Do notdeflect the high pressure fuel lines. Do not bend orstrike the high pressure fuel lines. Deformation ordamage of the high pressure fuel lines may cause apoint of weakness and potential failure.

Do not check the high pressure fuel lines with theengine or the starting motor in operation. After theengine has stopped allow 60 seconds to pass in orderto allow the pressure to be purged before any serviceor repair is performed on the engine fuel lines.

Do not loosen the high pressure fuel lines in orderto remove air from the fuel system. This procedureis not required.

Visually inspect the high pressure fuel lines beforethe engine is started. This inspection should be eachday.

If you inspect the engine in operation, always usethe proper inspection procedure in order to avoida fluid penetration hazard. Refer to Operation andMaintenance Manual, “General Hazard Information”.

• Inspect the high pressure for the following:damage, deformation, a nick, a cut, a crease, ora dent

NOTICEBecause the strength of the frame may decrease,some manufacturers do not recommend welding ontoa chassis frame or rail. Consult the OEM of the equip-ment or your Caterpillar dealer regarding welding ona chassis frame or rail.

Proper welding procedures are necessary in orderto avoid damage to the engine’s ECM, sensors,and associated components. When possible,remove the component from the unit and thenweld the component. If removal of the componentis not possible, the following procedure must befollowed when you weld on a unit that is equippedwith a Caterpillar Electronic Engine. The followingprocedure is considered to be the safest procedure toweld on a component. This procedure should providea minimum risk of damage to electronic components.

NOTICEDo not ground the welder to electrical componentssuch as the ECM or sensors. Improper grounding cancause damage to the drive train bearings, hydrauliccomponents, electrical components, and other com-ponents.

Clamp the ground cable from the welder to the com-ponent that will be welded. Place the clamp as closeas possible to the weld. This will help reduce the pos-sibility of damage.

1. Stop the engine. Turn the switched power to theOFF position.

2. Disconnect the negative battery cable from thebattery. If a battery disconnect switch is provided,open the switch.

3. Disconnect the J1/P1 and J2/P2 connectors fromthe ECM. Move the harness to a position that willnot allow the harness to accidentally move backand make contact with any of the ECM pins.


Use the example above. The current flow from the welder tothe ground clamp of the welder will not cause damage to anyassociated components.

(1) Engine(2) Welding electrode(3) Keyswitch in the OFF position(4) Battery disconnect switch in the open position(5) Disconnected battery cables(6) Battery(7) Electrical/Electronic component(8) Minimum distance between the component that is being welded

and any electrical/electronic component(9) The component that is being welded(10) Current path of the welder(11) Ground clamp for the welder

4. Connect the welding ground cable directly to thepart that will be welded. Place the ground cable asclose as possible to the weld in order to reduce thepossibility of welding current damage to bearings,hydraulic components, electrical components, andground straps.

Note: If electrical/electronic components are usedas a ground for the welder, or electrical/electroniccomponents are located between the welder groundand the weld, current flow from the welder couldseverely damage the component.

5. Protect the wiring harness from welding debrisand spatter.

6. Use standard welding practices to weld thematerials.

Electronic Engine FeaturesThe Caterpillar C-4.4 Engine is designed forelectronic controls. The integral on board computercontrols the operation of the engine. Currentoperating conditions are monitored. The ElectronicControl Module (ECM) controls the response of theengine to these conditions and to the demands of theoperator. These conditions and operator demandsdetermine the precise control of fuel injection by theECM. The electronic engine control system providesthe following features:

• Engine monitoring

• Engine speed governing

• Control of injection pressure

• Cold start strategy

• Automatic air/fuel ratio control

• Torque rise shaping

• Injection timing control

• System diagnostics

For more information on electronic engine features,refer to the Operation and Maintenance Manual,“Engine Features and Controls” topic (OperationSection).

Engine Diagnostics

The engine has built-in diagnostics in order to ensurethat the engine systems are functioning correctly.The operator will be informed of any change to aprogrammed limit. The operator will be alerted tothe condition by a “Stop or Warning” lamp that ismounted on the dashboard. Under certain conditions,the engine horsepower and the vehicle speed maybe limited. The Caterpillar Electronic Technician (ET)may be used to display the diagnostic codes.

There are three types of codes: active diagnostic,logged diagnostic, and event.

Most of the diagnostic codes are logged and storedin the ECM. For additional information, refer tothe Operation and Maintenance Manual, “EngineDiagnostics” topic (Operation Section).

The ECM provides an electronic governor thatcontrols the injector output in order to maintain thedesired engine rpm.

Engine Cooling and LubricationThe cooling system consists of the followingcomponents:

• Gear-driven centrifugal water pump

• Water temperature regulator which regulates theengine coolant temperature

• Gear-driven oil pump

• Oil cooler


The engine lubricating oil is supplied by a rotor typeoil pump. The engine lubricating oil is cooled and theengine lubricating oil is filtered. The bypass valvescan provide unrestricted flow of lubrication oil tothe engine if the oil filter element should becomeplugged.

Engine efficiency, efficiency of emission controls, andengine performance depend on adherence to properoperation and maintenance recommendations.Engine performance and efficiency also depend onthe use of recommended fuels, lubrication oils, andcoolants. Refer to this Operation and MaintenanceManual, “Maintenance Interval Schedule” for moreinformation on maintenance items.

Engine Service LifeEngine efficiency and maximum utilization of engineperformance depend on the adherence to properoperation and maintenance recommendations. Inaddition, use recommended fuels, coolants andlubricants. Use the Operation and MaintenanceManual as a guide for required engine maintenance.

Expected engine life is generally predicted by theaverage power that is demanded. The average powerthat is demanded is based on fuel consumption ofthe engine over a period of time. Reduced hours ofoperation at full throttle and/or operating at reducedthrottle settings result in a lower average powerdemand. Reduced hours of operation will increasethe length of operating time before an engineoverhaul is required. For more information, refer tothe Operation and Maintenance Manual, “OverhaulConsiderations” topic (Maintenance Section).

Aftermarket Products andCaterpillar EnginesWhen auxiliary devices, accessories, or consumables(filters, additives, catalysts, etc) which are madeby other manufacturers are used on Caterpillarproducts, the Caterpillar warranty is not affectedsimply because of such use.

However, failures that result from the installationor use of other manufacturers’ devices,accessories, or consumables are NOT Caterpillardefects. Therefore, the defects are NOT coveredunder the Caterpillar warranty.

NOTICENever bend the eyebolts and the brackets. Only loadthe eyebolts and the brackets under tension. Remem-ber that the capacity of an eyebolt is less as the anglebetween the supporting members and the object be-comes less than 90 degrees.

When it is necessary to remove a component at anangle, only use a link bracket that is properly rated forthe weight.

Use a hoist to remove heavy components. Usean adjustable lifting beam to lift the engine. Allsupporting members (chains and cables) should beparallel to each other. The chains and cables shouldbe perpendicular to the top of the object that is beinglifted.

Some removals require lifting the fixtures in order toobtain proper balance and safety.

To remove the engine ONLY, use the lifting eyes thatare on the engine.

Lifting eyes are designed and installed for the specificengine arrangement. Alterations to the lifting eyesand/or the engine make the lifting eyes and the liftingfixtures obsolete. If alterations are made, ensurethat proper lifting devices are provided. Consult yourCaterpillar dealer for information regarding fixturesfor proper engine lifting.

i02068367

Product StorageSMCS Code: 1000; 1404; 7002

If the engine will not be started for several weeks, thelubricating oil will drain from the cylinder walls andfrom the piston rings. Rust can form on the cylinderliner surface. Rust on the cylinder liner surface willcause increased engine wear and a reduction inengine service life.

To help prevent excessive engine wear, use thefollowing guidelines:

• Complete all of the lubrication recommendationsthat are listed in this Operation and MaintenanceManual, “Maintenance Interval Schedule”(Maintenance Section).

• If freezing temperatures are expected, check thecooling system for adequate protection againstfreezing. See this Operation and MaintenanceManual, “Refill Capacities and Recommendations”(Maintenance Section).

If an engine is out of operation and if use of the engineis not planned, special precautions should be made.If the engine will be stored for more than one month,a complete protection procedure is recommended.

For more detailed information on engine storage, seeSpecial Instruction, SEHS9031, “Storage ProcedureFor Caterpillar Products”.

Gauges and Indicators

Gauges and Indicatorsi02724238

Gauges and IndicatorsSMCS Code: 1900; 7450

Your engine may not have the same gauges or all ofthe gauges that are described. For more informationabout the gauge package, see the OEM information.

Gauges provide indications of engine performance.Ensure that the gauges are in good working order.Determine the normal operating range by observingthe gauges over a period of time.

Noticeable changes in gauge readings indicatepotential gauge or engine problems. Problems mayalso be indicated by gauge readings that changeeven if the readings are within specifications.Determine and correct the cause of any significantchange in the readings. Consult your Caterpillardealer for assistance.

Some engine applications are equipped with IndicatorLamps. Indicator lamps can be used as a diagnosticaid. There are two lamps. One lamp has an orangelens and the other lamp has a red lens.

These indicator lamps can be used in two ways:

• The indicator lamps can be used to identify thecurrent operational status of the engine. Theindicator lamps can also indicate that the enginehas a fault. This system is automatically operatedvia the ignition switch.

• The indicator lamps can be used to identify activediagnostic codes. This system is activated bypressing the Flash Code button.

Refer to the Troubleshooting Guide, “IndicatorLamps” for further information.

NOTICEIf no oil pressure is indicated, STOP the engine. Ifmaximum coolant temperature is exceeded, STOPthe engine. Engine damage can result.

Engine Oil Pressure – The oil pressureshould be greatest after a cold engine isstarted. The typical engine oil pressure with

SAE10W40 is 350 to 450 kPa ( 50 to 65 psi) at ratedrpm.

A lower oil pressure is normal at low idle. If the loadis stable and the gauge reading changes, performthe following procedure:

1. Remove the load.

2. Stop the engine.

3. Check and maintain the oil level.

Jacket Water Coolant Temperature –Typical temperature range is 83° to 95°C(181.4° to 171°F). The maximum allowable

temperature at sea level with the pressurized coolingsystem at 48 kPa (7 psi) is 103 °C (217.4 °F). Highertemperatures may occur under certain conditions.The water temperature reading may vary accordingto load. The temperature reading should neverexceed 7 °C (44.6 °F) below the boiling point for thepressurized system that is being used.

A 100 kPa (14.5 psi) radiator cap may be installed onthe cooling system. The temperature of this coolingsystem must not exceed 112 °C (233.6 °F).

If the engine is operating above the normal rangeand steam becomes apparent, perform the followingprocedure:

1. Reduce the load and the engine rpm.

2. Determine if the engine must be shut downimmediately or if the engine can be cooled byreducing the load.

3. Inspect the cooling system for leaks.

Tachometer – This gauge indicates enginespeed (rpm). When the throttle control leveris moved to the full throttle position without

load, the engine is running at high idle. The engine isrunning at the full load rpm when the throttle controllever is at the full throttle position with maximumrated load.

NOTICETo help prevent engine damage, never exceed thehigh idle rpm. Overspeeding can result in seriousdamage to the engine. Operation at speeds exceed-ing high idle rpm should be kept to a minimum.

Ammeter – This gauge indicates theamount of charge or discharge in thebattery charging circuit. Operation of the

indicator should be to the “+” side of “0” (zero).

Fuel Level – This gauge indicates the fuellevel in the fuel tank. The fuel level gaugeoperates when the “START/STOP” switch

is in the “on” position.

If the Warning/Derate/Shutdown mode has beenselected and the warning indicator activates,bring the engine to a stop whenever possible. De-pending on the application, special precautionsshould be taken to avoid personal injury.

32 SEBU8180-01Operation SectionFeatures and Controls

The engine can be programmed to the followingmodes:

“Warning”

The “Warning” lamp and the warning signal (orangelamp) turn “ON” and the warning signal is activatedcontinuously in order to alert the operator that one ormore of the engine parameters is not within normaloperating range.

“Warning/Derate”

The “Diagnostic” lamp turns “ON” and the warningsignal (red lamp) is activated. After the warning, theengine power will be derated. The warning lamp willbegin to flash when the derating occurs.

The engine will be derated if the engine exceedspreset operational limits. The engine derate isachieved by restricting the amount of fuel that isavailable for each injection. The amount of thisreduction of fuel is dependent on the severity of thefault that has caused the engine derate, typically upto a limit of 50%. This reduction in fuel results in apredetermined reduction in engine power.

“Warning/Derate/Shutdown”

The “Diagnostic” lamp turns “ON” and the warningsignal (red lamp) is activated. After the warning,the engine power will be derated. The engine willcontinue at the rpm of the set derate until a shutdownof the engine occurs. The engine can be restartedafter a shutdown for use in an emergency.

A shutdown of the engine may occur in as littleas 20 seconds. The engine can be restarted aftera shutdown for use in an emergency. However,the cause of the initial shutdown may still exist.The engine may shut down again in as little as 20seconds.

If there is a signal for low oil pressure or for coolanttemperature, there will be a two second delay inorder to verify the condition.

For each of the programmed modes, refer toTroubleshooting Guide, “Indicator Lamps” for moreinformation on Indicator Lamps.

Failure of Sensors

All Sensors

A failure of any of the sensors may be caused by oneof the following malfunctions:

• Sensor output is open.

• Sensor output is shorted to “- battery” or “+ battery”.

• Measured reading of the sensor is out of thespecification.

Programmable Monitoring System(PMS)The Programmable Monitoring System determinesthe level of action that is taken by the ElectronicControl Module (ECM) in response to a conditionthat can damage the engine. These conditions areidentified by the ECM from the signals that areproduced from the following sensors.

• Coolant Temperature Sensor

• Intake manifold Air Temperature Sensor

• Intake manifold Pressure Sensor

• Fuel Pressure Sensor



• Engine Oil Pressure Sensor

• Primary Speed/Timing Sensor

• Secondary Speed/Timing Sensor

Coolant Temperature Sensor 1The coolant temperature sensor monitors enginecoolant temperature. The output of the ECM (5) canindicate a high coolant temperature through a relayor a lamp. The coolant temperature sensor is usedby the ECM to determine initiation of the Cold StartCondition.

Failure of the Coolant TemperatureSensor

The ECM (5) will detect a failure of the coolanttemperature sensor. The diagnostic lamp will warn theoperator about the status of the coolant temperaturesensor. A failure of the coolant temperature sensorwill not cause a shutdown of the engine or anyhorsepower change. In order to check the correctoperation of the sensor, refer to Troubleshooting,“Engine Temperature Sensor Circuit - Test”.

Intake Manifold Air TemperatureSensor 2Note: This sensor can have two different locations.The location will depend on the type of engine.

The intake manifold air temperature sensor measuresthe intake air temperature. A signal is sent to theECM (5). The intake manifold air temperature sensoris also used by the ECM to determine initiation of theCold Start Strategy.

In order to check the correct operation of the sensor,refer to Troubleshooting, “EngineTemperature SensorCircuit - Test”.

Intake Manifold Pressure Sensor 3The intake manifold pressure sensor measurespressure in the manifold. A signal is sent to the ECM(5).

Fuel Pressure Sensor 4The fuel pressure sensor measures the fuel pressurein the fuel manifold. A signal is sent to the ECM (5).

Electronic Control Module 5The ECM is the control computer of the engine. TheECM provides power to the electronics. The ECMmonitors data that is input from the sensors of theengine. The ECM acts as a governor in order tocontrol the speed and the power of the engine.

The ECM adjusts injection timing and fuel pressurefor the best engine performance, the best fueleconomy and the best control of exhaust emissions.

Primary Speed/Timing Sensor 6If the ECM (5) does not receive a signal from theprimary speed/timing sensor , the “DIAGNOSTIC”lamp will indicate a diagnostic fault code which will belogged in the ECM memory.

If the ECM does not receive a signal from the primaryspeed/timing sensor (7), the ECM will read the signalfrom the secondary speed/timing sensor (8). TheECM continually checks in order to determine if thereis a signal from both sensors.

Intermittent failure of the sensors will cause erraticengine control.

Failure of the Primary Speed/TimingSensor

Correct operation of the primary speed/timingsensor is essential. Software in the ECM protectsagainst reverse running of the engine. If the primaryspeed/timing sensor fails there is no automaticprotection against reverse running. In someapplications, it is possible for the transmission torun the engine in reverse. In this event, Stop theengine immediately. Turn the keyswitch to the “OFF”position.

In order to check the correct operation of the sensor,refer to Troubleshooting, “Engine speed/Timingsensor - Test”.

Secondary Speed/Timing Sensor 7The signal from the secondary speed/timing sensoris used by the ECM (5) on engine start-up in orderto check the stroke of the pistons. The secondaryspeed/timing sensor may be used by the ECMin order to operate the engine if the primaryspeed/timing sensor is faulty.

In order to check the correct operation of the sensor,refer to Troubleshooting, “Engine speed/Timingsensor-Test”.


Engine Oil Pressure Sensor 8Note: This sensor can have two different locations.The location will depend on the type of engine.

The engine oil pressure sensor is an absolutepressure sensor that measures the engine oilpressure in the main oil gallery. The engine oilpressure sensor detects engine oil pressure fordiagnostic purposes. The engine oil pressure sensorsends a signal to the ECM (5).

Low Oil Pressure Warning

The setpoint for the low pressure warning isdependent upon the engine speed. The fault will beactive and logged only if the engine has been runningfor more than 8 seconds.

Very Low Oil Pressure Warning

The very low oil pressure setpoint is dependentupon the engine speed. If the DERATE mode of theengine monitoring system is selected, the ECM (5)will derate the engine power. The engine horsepowerwill be limited.

Failure of the Engine Oil Pressure Sensor

The ECM (5) will detect failure of the engine oilpressure sensor. The diagnostic lamp warns the userabout the status of the engine oil pressure sensor.The engine oil pressure related strategies will bedisabled in the event of a failure of the engine oilpressure sensor. A failure of the engine oil pressuresensor will not cause a shutdown of the engine orany horsepower change. In order to check the correctoperation of the sensor, refer to Troubleshooting, “5Volt Sensor Supply Circuit - Test”.

• Types and locations of shutoff

• Conditions which cause each shutoff to function

• The resetting procedure that is required to restartthe engine

AlarmsThe alarms are electrically operated. The operationof the alarms are controlled by the ECM.

The alarm is operated by a sensor or by a switch.When the sensor or the switch is activated a signalis sent to the ECM. An event code is created bythe ECM. The ECM will send a signal in order toilluminate the lamp.

Your engine may be equipped with the followingsensors or switches:

Coolant level – The low coolant level switchindicates when the coolant level is low.

Coolant temperature – The coolant temperaturesensor indicates high jacket water coolanttemperature.

Intake manifold air temperature – The intakemanifold air temperature sensor indicates high intakeair temperature.

Intake manifold pressure – The intake manifoldpressure sensor checks the rated pressure in theengine manifold.

Fuel rail pressure – The fuel rail pressure sensorchecks for high pressure or low pressure in the fuelrail.

Engine oil pressure – The engine oil pressuresensor indicates when oil pressure drops below ratedsystem pressure, at a set engine speed.



Engine overspeed – The primary speed/timingsensor checks the engine speed. The alarm isactivated at 3000 RPM.

Air filter restriction – The switch checks the airfilter when the engine is operating.

User defined switch – This switch can shut downthe engine remotely.

Water in fuel switch – This switch checks for waterin the primary fuel filter when the engine is operating.

Note: The sensing element of the coolanttemperature switch must be submerged in coolantin order to operate.

Engines may be equipped with alarms in orderto alert the operator when undesirable operatingconditions occur.

NOTICEWhen an alarm is activated, corrective measuresmustbe taken before the situation becomes an emergencyin order to avoid possible engine damage.

If corrective measures are not taken within areasonable time, engine damage could result. Thealarm will continue until the condition is corrected.The alarm may need to be reset.

Use the following procedure to retrieve the flashcodes if the engine is equipped with a “DIAGNOSTIC”lamp:

1. Turn the keyswitch “ON/OFF” two times within 3seconds.

A flashing“YELLOW” lamp indicates a 3 digit code forthe engine. The sequence of flashes represents thesystem diagnostic message. Count the first sequenceof flashes in order to determine the first digit of theflash code. After a two second pause, the secondsequence of flashes will identify the second digit ofthe flash code. After the second pause, the thirdsequence of flashes will identify the flash code.

Any additional flash codes will follow after a pause.These codes will be displayed in the same manner.Flash Code 551 indicates that No Detected Faultshave occurred since the ignition keyswitch has beenturned to the ON position.

For further information, assistance for repairs, ortroubleshooting, refer to the Service Manual orconsult an authorized Caterpillar dealer.

Table 3 lists the flash codes and the table also givesa brief description of the flash codes.

Note: Table 3 indicates the potential effect on engineperformance with “ACTIVE” flash codes.

Some codes record events. Also, some codesmay also indicate that a mechanical system needsattention. Troubleshooting is not required for code“551”. Code 001 will not display a flash code. Somecodes will limit the operation or the performance ofthe engine.

Table 3 indicates the potential effect on the engineperformance with active flash codes. Table 3 alsoforms a list of Electronic diagnostic codes anddescriptions.

Engine Operation with ActiveDiagnostic CodesSMCS Code: 1000; 1900; 1901; 1902

If a diagnostic lamp illuminates during normal engineoperation, the system has identified a situation that isnot within the specification. Use Caterpillar electronicservice tools to check the active diagnostic codes.

Note: If the customer has selected “DERATE” and ifthere is a low oil pressure condition, the ElectronicControl Module (ECM) will limit the engine poweruntil the problem is corrected. If the oil pressure iswithin the normal range, the engine may be operatedat the rated speed and load. However, maintenanceshould be performed as soon as possible.

The active diagnostic code should be investigated.The cause of the problem should be corrected assoon as possible. If the cause of the active diagnosticcode is repaired and there is only one activediagnostic code, the diagnostic lamp will turn off.

Operation of the engine and performance of theengine can be limited as a result of the activediagnostic code that is generated. Accelerationrates may be significantly slower. Refer to theTroubleshooting Guide for more information on therelationship between these active diagnostic codesand engine performance.

After Starting EngineSMCS Code: 1000

Note: In ambient temperatures from 0 to 60°C(32 to 140°F), the warm-up time is approximatelythree minutes. In temperatures below 0°C (32°F),additional warm-up time may be required.

When the engine idles during warm-up, observe thefollowing conditions:

Do not check the high pressure fuel lines with theengine or the starting motor in operation. If youinspect the engine in operation, always use theproper inspection procedure in order to avoid afluid penetration hazard. Refer to Operation andMaintenance Manual, “General hazard Information”.

• Check for any fluid or for any air leaks at idle rpmand at one-half full rpm (no load on the engine)before operating the engine under load. This is notpossible in some applications.

• Allow the engine to idle for three to five minutes, orallow the engine to idle until the water temperatureindicator begins to rise. Check all gauges duringthe warm-up period.

Note: Gauge readings should be observed andthe data should be recorded frequently while theengine is operating. Comparing the data over timewill help to determine normal readings for eachgauge. Comparing data over time will also helpdetect abnormal operating developments. Significantchanges in the readings should be investigated.

Proper operation and maintenance are key factorsin obtaining the maximum life and economy ofthe engine. If the directions in the Operation andMaintenance Manual are followed, costs can beminimized and engine service life can be maximized.

The time that is needed for the engine to reachnormal operating temperature can be less than thetime taken for a walk-around inspection of the engine.

The engine can be operated at the rated rpm afterthe engine is started and after the engine reachesoperating temperature. The engine will reach normaloperating temperature sooner during a low enginespeed (rpm) and during a low power demand. Thisprocedure is more effective than idling the engineat no load. The engine should reach operatingtemperature in a few minutes.

Gauge readings should be observed and the datashould be recorded frequently while the engineis operating. Comparing the data over time willhelp to determine normal readings for each gauge.Comparing data over time will also help detectabnormal operating developments. Significantchanges in the readings should be investigated.

Engaging the DrivenEquipmentSMCS Code: 1000

1. Operate the engine at one-half of the rated rpm,when possible.

2. Engage the driven equipment without a load onthe equipment, when possible.

Interrupted starts put excessive stress on the drivetrain. Interrupted starts also waste fuel. To get thedriven equipment in motion, engage the clutchsmoothly with no load on the equipment. Thismethod should produce a start that is smooth andeasy. The engine rpm should not increase and theclutch should not slip.

3. Ensure that the ranges of the gauges are normalwhen the engine is operating at one-half ofthe rated rpm. Ensure that all gauges operateproperly.

4. Increase the engine rpm to the rated rpm. Alwaysincrease the engine rpm to the rated rpm beforethe load is applied.

5. Apply the load. Begin operating the engine at lowload. Check the gauges and equipment for properoperation. After normal oil pressure is reachedand the temperature gauge begins to move,the engine may be operated at full load. Checkthe gauges and equipment frequently when theengine is operated under load.

Extended operation at low idle or at reduced loadmay cause increased oil consumption and carbonbuildup in the cylinders. This carbon buildupresults in a loss of power and/or poor performance.

Cold Weather Operation

Cold Weather Operationi02724382

Cold Weather OperationSMCS Code: 1000; 1250

Caterpillar Diesel Engines can operate effectively incold weather. During cold weather, the starting andthe operation of the diesel engine is dependent onthe following items:

• The type of fuel that is used

• The viscosity of the engine oil

• The operation of the glow plugs

• Optional Cold starting aid

• Battery condition

Refer to Special Publication, SEBU5898, “ColdWeather Recommendations for CaterpillarMachines”.

This section will cover the following information:

• Potential problems that are caused by cold weatheroperation

• Suggest steps which can be taken in order tominimize starting problems and operating problemswhen the ambient air temperature is between0° to −40 °C (32° to 40 °F).

The operation and maintenance of an engine infreezing temperatures is complex . This is becauseof the following conditions:

• Weather conditions

• Engine applications

Recommendations from your Carerpillar dealer arebased on past proven practices. The information thatis contained in this section provides guidelines forcold weather operation.

Hints for Cold Weather Operation• If the engine will start, operate the engine until aminimum operating temperature of 81 °C (177.8 °F)is achieved. Achieving operating temperature willhelp prevent the intake valves and exhaust valvesfrom sticking.

• The cooling system and the lubrication systemfor the engine do not lose heat immediately uponshutdown. This means that an engine can be shutdown for a period of time and the engine can stillhave the ability to start readily.

• Install the correct specification of engine lubricantbefore the beginning of cold weather.

• Check all rubber parts (hoses, fan drive belts, etc)weekly.

• Check all electrical wiring and connections for anyfraying or damaged insulation.

• Keep all batteries fully charged and warm.

• Fill the fuel tank at the end of each shift.

• Check the air cleaners and the air intake daily.Check the air intake more often when you operatein snow.

• Ensure that the glow plugs are in working order.Refer to Testing and Adjusting Manual, “Glow Plug- Test”.

Personal injury or property damage can resultfrom alcohol or starting fluids.

Alcohol or startingfluids are highly flammable andtoxic and if improperly stored could result in injuryor property damage.


• For jump starting with cables in cold weather,refer to the Operation and Maintenance Manual,“Starting with Jump Start Cables.” for instructions.

Viscosity of the Engine LubricationOilCorrect engine oil viscosity is essential. Oil viscosityaffects the amount of torque that is needed tocrank the engine. Refer to this Operation andMaintenance Manual, “Fluid Recommendations” forthe recommended viscosity of oil.

50 SEBU8180-01Operation SectionCold Weather Operation

Recommendations for the CoolantProvide cooling system protection for the lowestexpected outside temperature. Refer to this Operationand Maintenance Manual, “Fluid Recommendations”for the recommended coolant mixture.

In cold weather, check the coolant often for thecorrect glycol concentration in order to ensureadequate freeze protection.

Engine Block Heaters

Engine block heaters (if equipped) heat theengine jacket water that surrounds the combustionchambers. This provides the following functions:

• Startability is improved.

• Warm up time is reduced.

An electric block heater can be activated oncethe engine is stopped. An effective block heater istypically a 1250/1500 W unit. Consult your Caterpillardealer for more information.

Idling the EngineWhen idling after the engine is started in coldweather, increase the engine rpm from 1000 to 1200rpm. This will warm up the engine more quickly.Maintaining an elevated low idle speed for extendedperiods will be easier with the installation of a handthrottle. The engine should not be “raced” in order tospeed up the warm up process.

While the engine is idling, the application of a lightload (parasitic load) will assist in achieving theminimum operating temperature. The minimumoperating temperature is 82 °C (179.6 °F).

Recommendations for CoolantWarm UpWarm up an engine that has cooled below normaloperating temperatures due to inactivity. This shouldbe performed before the engine is returned to fulloperation. During operation in very cold temperatureconditions, damage to engine valve mechanisms canresult from engine operation for short intervals. Thiscan happen if the engine is started and the engine isstopped many times without being operated in orderto warm up completely.

When the engine is operated below normal operatingtemperatures, fuel and oil are not completely burnedin the combustion chamber. This fuel and oil causessoft carbon deposits to form on the valve stems.Generally, the deposits do not cause problems andthe deposits are burned off during operation atnormal engine operating temperatures.

When the engine is started and the engine is stoppedmany times without being operated in order to warmup completely, the carbon deposits become thicker.This can cause the following problems:

• Free operation of the valves is prevented.

• Valves become stuck.

• Pushrods may become bent.

• Other damage to valve train components canresult.

For this reason, when the engine is started,the engine must be operated until the coolanttemperature is 71 °C (160 °F) minimum. Carbondeposits on the valve stems will be kept at a minimumand the free operation of the valves and the valvecomponents will be maintained.

In addition, the engine must be thoroughly warmed inorder to keep other engine parts in better conditionand the service life of the engine will be generallyextended. Lubrication will be improved. There will beless acid and less sludge in the oil. This will providelonger service life for the engine bearings, the pistonrings, and other parts. However, limit unnecessaryidle time to ten minutes in order to reduce wear andunnecessary fuel consumption.

The Water Temperature Regulator andInsulated Heater Lines

The engine is equipped with a water temperatureregulator. When the engine coolant is below thecorrect operating temperature jacket water circulatesthrough the engine cylinder block and into theengine cylinder head. The coolant then returns to thecylinder block via an internal passage that bypassesthe valve of the coolant temperature regulator. Thisensures that coolant flows around the engine undercold operating conditions. The water temperatureregulator begins to open when the engine jacketwater has reached the correct minimum operatingtemperature. As the jacket water coolant temperaturerises above the minimum operating temperature thewater temperature regulator opens further allowingmore coolant through the radiator to dissipate excessheat.



The progressive opening of the water temperatureregulator operates the progressive closing of thebypass passage between the cylinder block andhead. This ensures maximum coolant flow tothe radiator in order to achieve maximum heatdissipation.

Note: Caterpillar discourages the use of all airflow restriction devices such as radiator shutters.Restriction of the air flow can result in the following:high exhaust temperatures, power loss, excessivefan usage, and reduction in fuel economy.

A cab heater is beneficial in very cold weather. Thefeed from the engine and the return lines from thecab should be insulated in order to reduce heat lossto the outside air.

Insulating the Air Inlet and EngineCompartment

When temperatures below −18 °C (−0 °F) will befrequently encountered, an air cleaner inlet thatis located in the engine compartment may bespecified. An air cleaner that is located in the enginecompartment may also minimize the entry of snowinto the air cleaner. Also, heat that is rejected by theengine helps to warm the intake air.

Additional heat can be retained around the engine byinsulating the engine compartment.

i01457051

Radiator RestrictionsSMCS Code: 1353; 1396

Caterpillar discourages the use of airflow restrictiondevices that are mounted in front of radiators. Airflowrestriction can cause the following conditions:

• High exhaust temperatures

• Power loss

• Excessive fan usage

• Reduction in fuel economy

If an airflow restriction device must be used, thedevice should have a permanent opening directlyin line with the fan hub. The device must have aminimum opening dimension of at least 770 cm2

(120 in2).

A centered opening that is directly in line with the fanhub is specified in order to prevent an interruptedairflow on the fan blades. Interrupted airflow on thefan blades could cause a fan failure.

Caterpillar recommends a warning device for theinlet manifold temperature and/or the installation ofan inlet air temperature gauge. The warning devicefor the inlet manifold temperature should be set at75 °C (167 °F). The inlet manifold air temperatureshould not exceed 75 °C (167 °F). Temperatures thatexceed this limit can cause power loss and potentialengine damage.

i02237624

Fuel and the Effect from ColdWeatherSMCS Code: 1000; 1250

The following fuels are the grades that are availablefor Caterpillar engines:

• No. 1

• No. 2

• Blend of No. 1 and No. 2

No. 2 diesel fuel is the most commonly used fuel.Either No. 1 diesel fuel or a blend of No. 1 and No. 2is best suited for cold weather operation.

52 SEBU8180-01Operation SectionCold Weather Operation

Quantities of No. 1 diesel fuel are limited. No. 1 dieselfuels are usually available during the months of thewinter in the colder climates. During cold weatheroperation, if No. 1 diesel fuel is not available, use No.2 diesel fuel, if necessary.

There are three major differences between No. 1 andNo. 2 diesel fuel. No. 1 diesel fuel has the followingproperties:

• Lower cloud point

• Lower pour point

• Lower rating of kJ (BTU) per unit volume of fuel

When No. 1 diesel fuel is used, a decrease in powerand in fuel efficiency may be noticed. Other operatingeffects should not be experienced.

The cloud point is the temperature when a cloud ofwax crystals begins to form in the fuel. These crystalscan cause the fuel filters to plug. The pour point isthe temperature when diesel fuel will thicken. Thediesel fuel becomes more resistant to flow throughfuel pumps and through fuel lines.

Be aware of these values when diesel fuel ispurchased. Anticipate the average ambienttemperature of the area. Engines that are fueled inone climate may not operate well if the engines aremoved to another climate. Problems can result dueto changes in temperature.

Before troubleshooting for low power or for poorperformance in the winter, check the type of fuel thatis being used.

When No. 2 diesel fuel is used the followingcomponents provide a means of minimizing problemsin cold weather:

• Starting aids

• Engine oil pan heaters

• Engine coolant heaters

• Fuel heaters

• Fuel line insulation

Fuel TanksCondensation can form in partially filled fuel tanks.Top off the fuel tanks after you operate the engine.

Fuel tanks should contain some provision for drainingwater and sediment from the bottom of the tanks.Some fuel tanks use supply pipes that allow waterand sediment to settle below the end of the fuelsupply pipe.

Some fuel tanks use supply lines that take fueldirectly from the bottom of the tank. If the engine isequipped with this system, regular maintenance ofthe fuel system filter is important.

Drain the water and sediment from any fuel storagetank at the following intervals: weekly, serviceintervals, and refueling of the fuel tank. This will helpprevent water and/or sediment from being pumpedfrom the fuel storage tank and into the engine fueltank.

Fuel FiltersAfter you change the fuel filter, always prime the fuelsystem in order to remove air bubbles from the fuelsystem. Refer to the Operation and MaintenanceManual in the Maintenance Section for moreinformation on priming the fuel system.

The micron rating and the location of a primary fuelfilter is important in cold weather operation. Theprimary fuel filter and the fuel supply line are the mostcommon components that are affected by cold fuel.

NOTICEIn order to maximize fuel system life and prevent pre-mature wear out from abrasive particles in the fuel, afour micron[c] absolute high efficiency fuel filter is re-quired for all Caterpillar Hydraulic Electronic Unit In-jectors. Caterpillar High Efficiency Fuel Filters meetthese requirements. Consult your Caterpillar dealerfor the proper part numbers.

Fuel HeatersFuel heaters help to prevent fuel filters from pluggingin cold weather due to waxing. A fuel heater shouldbe installed in the fuel system before the primaryfuel filter.



The following fuel heaters are recommended forCaterpillar engines:

• 7C-3557 Fuel Heater Group

• 7C-3558 Heater Kit

For further information on fuel heaters, consult yourCaterpillar dealer.

Disconnect the fuel heater in warm weather.

Note: Fuel heaters that are controlled by the watertemperature regulator or self-regulating fuel heatersshould be used with this engine. Fuel heaters thatare not controlled by the water temperature regulatorcan heat the fuel in excess of 65°C (149°F). A loss ofengine power can occur if the fuel supply temperatureexceeds 37°C (100°F).

Note: Heat exchanger type fuel heaters should havea bypass provision in order to prevent overheating ofthe fuel in warm weather operation.

Cat DEO (Diesel Engine Oil)

Caterpillar Oils have been developed and tested inorder to provide the full performance and servicelife that has been designed and built into CaterpillarEngines. Caterpillar Oils are currently used to filldiesel engines at the factory. These oils are offeredby Caterpillar dealers for continued use when theengine oil is changed. Consult your Caterpillar dealerfor more information on these oils.

Due to significant variations in the quality and inthe performance of commercially available oils,Caterpillar makes the following recommendations:

• Cat DEO (Diesel Engine Oil) (10W-30)

• Cat DEO (Diesel Engine Oil) (15W-40)

Caterpillar multigrade DEO is formulated with thecorrect amounts of detergents, dispersants, andalkalinity in order to provide superior performance inCaterpillar Diesel Engines.

Caterpillar multigrade DEO is available in variousviscosity grades that include SAE 10W-30 and SAE15W-40. To choose the correct viscosity grade forthe ambient temperature, see Table 6. Multigradeoils provide the correct viscosity for a broad range ofoperating temperatures.

Multigrade oils are effective in maintaining low oilconsumption and low levels of piston deposits.

SEBU8180-01 55Maintenance Section

Refill Capacities

Caterpillar multigrade DEO can be used in otherdiesel engines and in gasoline engines. See theengine manufacturer’s guide for the recommendedspecifications. Compare the specifications to thespecifications of Caterpillar multigrade DEO. Thecurrent industry standards for Caterpillar DEO arelisted on the product label and on the data sheetsfor the product.

Consult your Caterpillar dealer for part numbers andfor available sizes of containers.

Note: Caterpillar SAE 15W-40 multigrade DEOexceeds the performance requirements for thefollowing API classifications: CI-4, CH-4, CG-4, CF-4,and CF. The Caterpillar multigrade DEO exceeds therequirements of the Caterpillar specification that isECF-1 (Engine Crankcase Fluid-1). The CaterpillarSAE 15W-40 multigrade DEO passes the followingproprietary tests: sticking of the piston ring, oil controltests, wear tests, and soot tests. Proprietary testshelp ensure that Caterpillar multigrade oil providessuperior performance in Caterpillar Diesel Engines.In addition, Caterpillar multigrade oil exceedsmany of the performance requirements of othermanufacturers of diesel engines. Therefore, this oil isan excellent choice for many mixed fleets. True highperformance oil is produced with a combinationof the following factors: industry standard tests,proprietary tests, field tests, and prior experiencewith similar formulations. The design and thedevelopment of Caterpillar lubricants that areboth high performance and high quality arebased on these factors.

Note: Non-Caterpillar commercial oils are secondchoice oils.

Commercial Oils

In order to select the correct engine oil for the C-4.4electronic engine, you must refer to table 5.

Table 5

API Classifications for the C-4.4 electronicIndustrial Engine

Oil Specification MaintenanceInterval

CH-4/CI-4 500 Hours

CI-4 500 Hours

CG-4 250 Hours

Note: If Caterpillar Multigrade DEO is not used,use only commercial oils that meet the followingclassifications.

• API CH-4 multigrade oils and API CI-4 multigradeoils are acceptable if the requirements ofCaterpillar’s ECF-1 (Engine Crankcase Fluidspecification-1) are met. CH-4 oils and CI-4 oilsthat have not met the requirements of Caterpillar’sECF-1 Specification may cause reduced enginelife.

• API CF-4 multigrade oils are not recommended forthis series of diesel engines. For all other smallercommercial diesel engines, the oil drain intervalshould not exceed 50 percent of the standard oildrain interval for your engine.

NOTICEIn selecting oil for any engine application, both the oilviscosity and oil performance classification/specifica-tion as specified by the engine manufacturer must bedefined and satisfied. Using only one of these param-eters will not sufficiently define oil for an engine appli-cation.

In order to make the proper choice of a commercialoil, refer to the following explanations:

API CI-4 – API CI-4 oils were developed in orderto meet the requirements of high performancediesel engines that use cooled Exhaust GasRecirculation (EGR). API CI-4 oils are acceptableif the requirements of Caterpillar’s ECF-1 (EngineCrankcase Fluid specification-1) are met.

API CH-4 – API CH-4 oils were developed in orderto protect low emissions diesel engines that use a0.05 percent level of fuel sulfur. However, API CH-4oils may be used with higher sulfur fuels. API CH-4oils are acceptable if the requirements of Caterpillar’sECF-1 (Engine Crankcase Fluid specification-1) aremet.

Note: CH-4 oils and CI-4 oils that have not met therequirements of Caterpillar’s ECF-1 Specificationmay cause reduced engine life.

NOTICEFailure to follow these oil recommendations can causeshortened engine service life due to deposits and/orexcessive wear.

Note: Refer to Special Publication, SEBU6251,“Caterpillar Commercial Diesel Engine FluidsRecommendations” for additional information thatrelates to lubrication for your engine.

Lubricant Viscosity Recommendations

The proper SAE viscosity grade of oil is determinedby the minimum ambient temperature duringcold engine start-up, and the maximum ambienttemperature during engine operation.


Refer to Table 6 (minimum temperature) in order todetermine the required oil viscosity for starting a coldengine.

Refer to Table 6 (maximum temperature) in order toselect the oil viscosity for engine operation at thehighest ambient temperature that is anticipated.

Note: Generally, use the highest oil viscosity that isavailable to meet the requirement for the temperatureat start-up.

If ambient temperature conditions at engine start-uprequire the use of multigrade SAE 0W oil, SAE0W-40 viscosity grade is preferred over SAE 0W-20or SAE 0W-30.

S·O·S Oil Analysis

Caterpillar has developed a tool for maintenancemanagement that evaluates oil degradation and thetool also detects the early signs of wear on internalcomponents. The Caterpillar tool for oil analysis iscalled S·O·S Oil Analysis and the tool is part of theS·O·S Services program. S·O·S Oil Analysis dividesoil analysis into three categories:

• Wear Analysis

• Oil condition

• Additional tests

The wear analysis monitors metal particles, some oiladditives, and some contaminants.

Oil condition uses infrared (IR) analysis to evaluatethe chemistry of the oil. Infrared analysis is also usedto detect certain types of contamination.

Additional tests are used to measure contaminationlevels from water, fuel, or coolant. Oil viscosity andcorrosion protection can be evaluated, as needed.

Refer to Special Publication, SEBU6251, “CaterpillarCommercial Diesel Engine Fluids Recommendations”or contact your local Caterpillar dealer for additionalinformation concerning the S·O·S Oil Analysisprogram.

Refill Capacities for the LubricationSystem

The refill capacities for the engine crankcase reflectthe approximate capacity of the crankcase or sumpplus standard oil filters. Auxiliary oil filter systems willrequire additional oil. Refer to the OEM specificationsfor the capacity of the auxiliary oil filter.

Lubricating GreaseCaterpillar provides a range of moderate greasesto extremely high performance greases in order toservice the entire line of Caterpillar products thatoperate throughout the wide variety of climates.From this variety of Caterpillar grease products, youwill find at least one of the Caterpillar greases thatwill satisfy the performance requirements for anymachine or equipment application.

Before selecting a grease for any application, theperformance requirements must be determined.Consult the grease recommendations that are madeby the OEM for the equipment when the equipment isoperated in the expected conditions. Then, consultwith your Caterpillar dealer for a list of greases andthe following related characteristics.

• Performance specifications

• Available sizes of containers

• Part numbers

Always choose a grease that satisfies therecommendations that are specified by theequipment manufacturer for the application.


Refill Capacities

Note: If it is necessary to choose a single greaseto use for all of the equipment at one site, alwayschoose a grease that satisfies the requirementsof the most demanding application.

Do not use the cost per pound as the only factorwhen you choose a grease. Use the grease thatyields the lowest total cost of operation. The costanalysis should include the following factors:

• Parts

• Labor

• Downtime

• Cost of the grease

Greases that barely meet the minimum performancerequirements can be expected to barely produce theminimum life of the parts.

Note: Take care when you change the type of grease.Take care when you change to a different supplier ofgrease. Some greases are not chemically compatible.Some brands of grease can not be interchanged. Ifyou are in doubt about the compatibility of theold grease and the new grease, purge all of theold grease from the joint. Consult your supplier inorder to determine if the greases are compatible.

Note: All Caterpillar brand of greases arecompatible with each other.

Note: Refer to Special Publication, SEBU6251,“Caterpillar Commercial Diesel Engine FluidsRecommendations” for additional information thatrelates to lubrication for your engine.

General Fuel InformationDiesel fuels that meet the Caterpillar Specificationfor Distillate Diesel Fuel are recommended. Thesefuels will help to provide maximum engine service lifeand performance. In North America, diesel fuel thatis identified as No. 1-D or No. 2-D in “ASTM D975”generally meet the specifications. Diesel fuels fromother sources could exhibit detrimental propertiesthat are not defined or controlled by this specification.

NOTICEOperating with fuels that do not meet Caterpillar’s rec-ommendations can cause the following effects: start-ing difficulty, poor combustion, deposits in the fuel in-jectors, reduced service life of the fuel system, de-posits in the combustion chamber, and reduced ser-vice life of the engine.

Note: Refer to Special Publication, SEBU6251,“Caterpillar Commercial Diesel Engine FluidsRecommendations” for the Caterpillar Specificationfor distillate fuel and for additional information thatrelates to fuel for your engine.

General Coolant Information

NOTICEThese recommendations are subject to change with-out notice. Contact your local Caterpillar dealer for themost up to date fluids recommendations.

NOTICENever add coolant to an overheated engine. Enginedamage could result. Allow the engine to cool first.

NOTICEIf the engine is to be stored in, or shipped to an areawith below freezing temperatures, the cooling systemmust be either protected to the lowest outside temper-ature or drained completely to prevent damage.

NOTICEFrequently check the specific gravity of the coolant forproper freeze protection or for anti-boil protection.

Clean the cooling system for the following reasons:

• Contamination of the cooling system

• Overheating of the engine

• Foaming of the coolant

Note: Air pockets can form in the cooling system ifthe cooling system is filled at a rate that is greaterthan 5 L (1.3 US gal) per minute.

After you drain the cooling system and after you refillthe cooling system, operate the engine. Operate theengine without the filler cap until the coolant reachesnormal operating temperature and the coolant levelstabilizes. Ensure that the coolant is maintained tothe proper level.


NOTICENever operate an engine without water temperatureregulators in the cooling system. Water temperatureregulators help to maintain the engine coolant at theproper operating temperature. Cooling system prob-lems can develop without water temperature regula-tors.

Refer to Special Instruction, SEBD0518, “KnowYour Cooling System” and Special Instruction,SEBD0970, “Coolant and Your Engine” for moredetailed information.

Many engine failures are related to the coolingsystem. The following problems are related to coolingsystem failures: overheating, leakage of the waterpump, plugged radiators or heat exchangers, andpitting of the cylinder liners.

These failures can be avoided with proper coolingsystem maintenance. Cooling system maintenance isas important as maintenance of the fuel system andthe lubrication system. Quality of the coolant is asimportant as the quality of the fuel and the lubricatingoil.

Coolant is normally composed of three elements:water, additives, and glycol.

Water

NOTICENever use water alone without Supplemental CoolantAdditives (SCA) or without inhibited coolant. Wateralone is corrosive at engine operating temperatures.Water alone does not provide adequate protectionagainst boiling or freezing.

Water is used in the cooling system in order totransfer heat.

Distilled water or deionized water isrecommended for use in engine cooling systems.

DO NOT use the following types of water in coolingsystems: hard water, softened water that has beenconditioned with salt, and sea water.

If distilled water or deionized water is not available,use water with the properties that are listed in Table 8.

Table 8

Caterpillar Minimum Acceptable Water Requirements

Property Maximum Limit ASTM Test

Total Solids 340 mg/L(20 grain/US gal) “D1888”

Acidity pH of 5.5 to 9.0 “D1293”

For a water analysis, consult one of the followingsources:

• Caterpillar dealer

• Local water utility company

• Agricultural agent

• Independent laboratory

Additives

Additives help to protect the metal surfaces ofthe cooling system. A lack of coolant additives orinsufficient amounts of additives enable the followingconditions to occur:

• Corrosion

• Formation of mineral deposits

• Rust

• Scale

• Pitting and erosion from cavitation of the cylinderliner

• Foaming of the coolant

Many additives are depleted during engine operation.These additives must be replaced periodically.This can be done by adding Supplemental CoolantAdditives (SCA) to Diesel Engine Antifreeze/Coolant(DEAC) or by adding ELC Extender to Extended LifeCoolant (ELC).

Additives must be added at the proper concentration.Overconcentration of additives can cause theinhibitors to drop out-of-solution. The deposits canenable the following problems to occur:

• Formation of gel compounds


Refill Capacities

• Reduction of heat transfer

• Leakage of the water pump seal

• Plugging of radiators, coolers, and small passages

Glycol

Glycol in the coolant helps to provide protectionagainst the following conditions:

• Boiling

• Freezing

• Cavitation of the water pump and the cylinder liner

For optimum performance, Caterpillar recommends a1:1 mixture of a water/glycol solution.

Note: Use a mixture that will provide protectionagainst the lowest ambient temperature.

Note: 100 percent pure glycol will freeze at atemperature of −23 °C (−9 °F).

Most conventional heavy-duty antifreezes useethylene glycol. Propylene glycol may also be used.In a 1:1 mixture with water, ethylene and propyleneglycol provide similar protection against freezing andboiling. See Tables 9 and 10.

To check the concentration of glycol, use the1U-7298 Coolant/Battery Tester (Degrees Celsius)or use the 1U-7297 Coolant/Battery Tester (DegreesFahrenheit). The testers give readings that areimmediate and accurate. The testers can be usedwith ethylene or propylene glycol.

Coolant Recommendations

NOTICEDo not use a commercial coolant/antifreeze that on-ly meets the ASTM D3306 specification. This type ofcoolant/antifreeze is made for light duty automotiveapplications.

The following two coolants are used in Caterpillardiesel engines:

Preferred – Caterpillar Extended Life Coolant (ELC)or a commercial extended life coolant that meets theCaterpillar EC-1 specification

Acceptable – Caterpillar Diesel Engine Antifreeze(DEAC) or a commercial heavy-duty antifreezethat meets “ASTM D4985”, or “ASTM D6210”specifications

Caterpillar recommends a 1:1 mixture of water andglycol. This mixture of water and glycol will provideoptimum heavy-duty performance as a antifreeze.

Note: Caterpillar DEAC does not require a treatmentwith an SCA at the initial fill. A commercial heavy-dutyantifreeze that meets “ASTM D4985” or “ASTMD6210” specifications MAY require a treatment withan SCA at the initial fill. These coolants WILL requirea treatment with an SCA on a maintenance basis.

Refer to Special Publication, SEBU6251, “CaterpillarCommercial Diesel Engine Fluids Recommendations”for additional information that relates to coolant.

The S·O·S Coolant Analysis has the followingfeatures:

• Full coolant analysis (Level 1)

• Identification of the source of metal corrosion andof contaminants

• Water hardness

• Identification of buildup of the impurities that causecorrosion

• Identification of buildup of the impurities that causescaling

The results are reported, and appropriaterecommendations are made.

Refer to the Maintenance Interval Schedule inthis Operation and Maintenance Manual, “CoolingSystem Coolant Sample (Level 2) - Obtain” for asampling location and the maintenance interval forcollecting the coolant samples.

Testing the engine coolant is important to ensure thatthe engine is protected from internal cavitation andfrom corrosion. The analysis also tests the ability ofthe coolant to protect the engine from boiling andfrom freezing. The S·O·S Coolant Analysis can bedone at your Caterpillar dealer. Caterpillar S·O·SCoolant Analysis is the best way to monitor thecondition of your coolant and your cooling system.S·O·S Coolant Analysis is a program that is basedon periodic samples.

Cooling System WaterTemperature Regulator -ReplaceSMCS Code: 1355-510

Replace the water temperature regulator beforethe water temperature regulator fails. This is arecommended preventive maintenance practice.Replacing the water temperature regulator reducesthe chances for unscheduled downtime.

A water temperature regulator that fails in apartially opened position can cause overheating orovercooling of the engine.

A water temperature regulator that fails in the closedposition can cause excessive overheating. Excessiveoverheating could result in cracking of the cylinderhead or piston seizure problems.


Crankcase Breather (Canister) - Replace

A water temperature regulator that fails in the openposition will cause the engine operating temperatureto be too low during partial load operation. Lowengine operating temperatures during partial loadscould cause an excessive carbon buildup inside thecylinders. This excessive carbon buildup could resultin an accelerated wear of the piston rings and wearof the cylinder liner.

NOTICEFailure to replace your water temperature regulatoron a regularly scheduled basis could cause severeengine damage.

Caterpillar engines incorporate a shunt design coolingsystem and require operating the engine with a watertemperature regulator installed.

If the water temperature regulator is installed incor-rectly, the enginemay overheat, causing cylinder headdamage. Ensure that the new water temperature reg-ulator is installed in the original position. Ensure thatthe water temperature regulator vent hole is open.

Do not use liquid gasket material on the gasket orcylinder head surface.

Use clean primary air cleaner elements while dirtyelements are being cleaned.

NOTICEDo not clean the air cleaner elements by bumping ortapping. This could damage the seals. Do not use el-ements with damaged pleats, gaskets or seals. Dam-aged elements will allow dirt to pass through. Enginedamage could result.

Visually inspect the primary air cleaner elementsbefore cleaning. Inspect the air cleaner elements fordamage to the seal, the gaskets, and the outer cover.Discard any damaged air cleaner elements.

There are two common methods that are used toclean primary air cleaner elements:

• Pressurized air

• Vacuum cleaning

76 SEBU8180-01Maintenance SectionEngine Air Cleaner Element (Dual Element) - Clean/Replace

Pressurized Air

Pressurized air can be used to clean primary aircleaner elements that have not been cleaned morethan two times. Pressurized air will not removedeposits of carbon and oil. Use filtered, dry air with amaximum pressure of 207 kPa (30 psi).


Note: When the primary air cleaner elements arecleaned, always begin with the clean side (inside)in order to force dirt particles toward the dirty side(outside).

Aim the hose so that the air flows inside the elementalong the length of the filter in order to help preventdamage to the paper pleats. Do not aim the streamof air directly at the primary air cleaner element. Dirtcould be forced further into the pleats.

Note: Refer to “Inspecting the Primary Air CleanerElements”.

Vacuum Cleaning

Vacuum cleaning is a good method for cleaningprimary air cleaner elements which require dailycleaning because of a dry, dusty environment.Cleaning with pressurized air is recommended priorto vacuum cleaning. Vacuum cleaning will not removedeposits of carbon and oil.

Note: Refer to “Inspecting the Primary Air CleanerElements”.

Inspecting the Primary Air CleanerElements


Inspect the clean, dry primary air cleaner element.Use a 60 watt blue light in a dark room or in a similarfacility. Place the blue light in the primary air cleanerelement. Rotate the primary air cleaner element.Inspect the primary air cleaner element for tearsand/or holes. Inspect the primary air cleaner elementfor light that may show through the filter material. If itis necessary in order to confirm the result, comparethe primary air cleaner element to a new primary aircleaner element that has the same part number.

Do not use a primary air cleaner element that hasany tears and/or holes in the filter material. Do notuse a primary air cleaner element with damagedpleats, gaskets or seals. Discard damaged primaryair cleaner elements.

Storing Primary Air Cleaner Elements

If a primary air cleaner element that passes inspectionwill not be used, the primary air cleaner element canbe stored for future use.

Engine Oil Sample - ObtainSMCS Code: 1000-008; 1348-554-SM;7542-554-OC, SM

In addition to a good preventive maintenanceprogram, Caterpillar recommends using S·O·S oilanalysis at regularly scheduled intervals in orderto monitor the condition of the engine and themaintenance requirements of the engine. S·O·S oilanalysis provides infrared analysis, which is requiredfor determining nitration and oxidation levels.

Obtain the Sample and the Analysis


Before you take the oil sample, complete the Label,PEEP5031 for identification of the sample. In orderto help obtain the most accurate analysis, providethe following information:

• Engine model

• Service hours on the engine

• The number of hours that have accumulated sincethe last oil change

• The amount of oil that has been added since thelast oil change

To ensure that the sample is representative of theoil in the crankcase, obtain a warm, well mixed oilsample.

To avoid contamination of the oil samples, the toolsand the supplies that are used for obtaining oilsamples must be clean.

Caterpillar recommends using the sampling valvein order to obtain oil samples. The quality and theconsistency of the samples are better when thesampling valve is used. The location of the samplingvalve allows oil that is flowing under pressure to beobtained during normal engine operation.

The 169-8373 Fluid Sampling Bottle isrecommended for use with the sampling valve. Thefluid sampling bottle includes the parts that areneeded for obtaining oil samples. Instructions arealso provided.


If the engine is not equipped with a sampling valve,use the 1U-5718 Vacuum Pump. The pump isdesigned to accept sampling bottles. Disposabletubing must be attached to the pump for insertioninto the sump.

For instructions, see Special Publication, PEHP6001,“How To Take A Good Oil Sample”. Consult yourCaterpillar dealer for complete information andassistance in establishing an S·O·S program for yourengine.

80 SEBU8180-01Maintenance SectionEngine Oil and Filter - Change

Do not drain the engine lubricating oil when theengine is cold. As the engine lubricating oil cools,suspended waste particles settle on the bottom ofthe oil pan. The waste particles are not removed withdraining cold oil. Drain the oil pan with the enginestopped. Drain the oil pan with the oil warm. Thisdraining method allows the waste particles that aresuspended in the oil to be drained properly.

Failure to follow this recommended procedure willcause the waste particles to be recirculated throughthe engine lubrication system with the new oil.

Drain the Engine Lubricating OilNote: Ensure that the vessel that will be used is largeenough to collect the waste oil.

After the engine has been run at the normal operatingtemperature, stop the engine. Use one of thefollowing methods to drain the engine oil pan:


Typical example

• If the engine is equipped with a drain valve, turn thedrain valve knob counterclockwise in order to drainthe oil. After the oil has drained, turn the drain valveknob clockwise in order to close the drain valve.

• If the engine is not equipped with a drain valve,remove the oil drain plug (1) in order to allow the oilto drain. If the engine is equipped with a shallow oilpan, remove the bottom oil drain plugs from bothends of the oil pan.

After the oil has drained, the oil drain plugs should becleaned and installed. If necessary, replace the Oring seal. Tighten the drain plug to 34 N·m (25 lb ft).

Replace the Oil Filter

NOTICECaterpillar oil filters are manufactured to Caterpillarspecifications. Use of an oil filter that is not recom-mended by Caterpillar could result in severe damageto the engine bearings, crankshaft, etc., as a result ofthe larger waste particles from unfiltered oil enteringthe engine lubricating system. Only use oil filters rec-ommended by Caterpillar.

1. Remove the oil filter with a 1U-8760 ChainWrench.

NOTICECare must be taken to ensure that fluids are containedduring performance of inspection, maintenance, test-ing, adjusting, and repair of the product. Be preparedto collect the fluid with suitable containers beforeopening any compartment or disassembling any com-ponent containing fluids.


Fuel TankFuel quality is critical to the performance and to theservice life of the engine. Water in the fuel can causeexcessive wear to the fuel system.

Water can be introduced into the fuel tank when thefuel tank is being filled.

Condensation occurs during the heating and coolingof fuel. The condensation occurs as the fuel passesthrough the fuel system and the fuel returns to thefuel tank. This causes water to accumulate in fueltanks. Draining the fuel tank regularly and obtainingfuel from reliable sources can help to eliminate waterin the fuel.

Drain the Water and the SedimentFuel tanks should contain some provision for drainingwater and draining sediment from the bottom of thefuel tanks.

Open the drain valve on the bottom of the fuel tankin order to drain the water and the sediment. Closethe drain valve.

Check the fuel daily. Allow five minutes after thefuel tank has been filled before draining water andsediment from the fuel tank.

Fill the fuel tank after operating the engine inorder to drive out moist air. This will help preventcondensation. Do not fill the tank to the top. Thefuel expands as the fuel gets warm. The tank mayoverflow.

Some fuel tanks use supply pipes that allow waterand sediment to settle below the end of the fuelsupply pipe. Some fuel tanks use supply lines thattake fuel directly from the bottom of the tank. Ifthe engine is equipped with this system, regularmaintenance of the fuel system filter is important.

Fuel Storage TanksDrain the water and the sediment from the fuelstorage tank at the following intervals:

• Weekly

• Service intervals

• Refill of the tank

This will help prevent water or sediment from beingpumped from the storage tank into the engine fueltank.

If a bulk storage tank has been refilled or movedrecently, allow adequate time for the sediment tosettle before filling the engine fuel tank. Internalbaffles in the bulk storage tank will also help trapsediment. Filtering fuel that is pumped from thestorage tank helps to ensure the quality of the fuel.When possible, water separators should be used.

Hoses and Clamps -Inspect/ReplaceSMCS Code: 7554-040; 7554-510



Inspect all hoses for leaks that are caused by thefollowing conditions:

• Cracking

• Softness

• Loose clamps


Overhaul Considerations

Replace hoses that are cracked or soft. Tighten anyloose clamps.

Check for the following conditions:

• End fittings that are damaged or leaking

• Outer covering that is chafed or cut

• Exposed wire that is used for reinforcement

• Outer covering that is ballooning locally

• Flexible part of the hose that is kinked or crushed

• Armoring that is embedded in the outer covering

A constant torque hose clamp can be used in placeof any standard hose clamp. Ensure that the constanttorque hose clamp is the same size as the standardclamp.

Due to extreme temperature changes, the hose willharden. Hardening of the hoses will cause hoseclamps to loosen. This can result in leaks. A constanttorque hose clamp will help to prevent loose hoseclamps.

Each installation application can be different. Thedifferences depend on the following factors:

• Type of hose

• Type of fitting material

• Anticipated expansion and contraction of the hose

• Anticipated expansion and contraction of thefittings

Replace the Hoses and the ClampsRefer to the OEM information for further informationon removing and replacing fuel hoses (if equipped).

Overhaul ConsiderationsSMCS Code: 7595-043

Reduced hours of operation at full load will result in alower average power demand. A decreased averagepower demand should increase both the engineservice life and the overhaul interval.

The need for an overhaul is generally indicated byincreased fuel consumption and by reduced power.

The following factors are important when a decisionis being made on the proper time for an engineoverhaul:

• The need for preventive maintenance

• The quality of the fuel that is being used

• The operating conditions

• The results of the S·O·S analysis

94 SEBU8180-01Maintenance SectionOverhaul Considerations

Oil Consumption as an OverhaulIndicatorOil consumption, fuel consumption, and maintenanceinformation can be used to estimate the totaloperating cost for your Caterpillar engine. Oilconsumption can also be used to estimate therequired capacity of a makeup oil tank that is suitablefor the maintenance intervals.

Oil consumption is in proportion to the percentageof the rated engine load. As the percentage of theengine load is increased, the amount of oil that isconsumed per hour also increases.

The oil consumption rate (brake specific oilconsumption) is measured in grams per kW/h (lb perbhp). The brake specific oil consumption (BSOC)depends on the engine load. Consult your Caterpillardealer for assistance in determining the typical oilconsumption rate for your engine.

When an engine’s oil consumption has risen to threetimes the original oil consumption rate due to normalwear, an engine overhaul should be scheduled.There may be a corresponding increase in blowbyand a slight increase in fuel consumption.

Overhaul Options

Before Failure Overhaul

A planned overhaul before failure may be the bestvalue for the following reasons:

• Costly unplanned downtime can be avoided.

• Many original parts can be reused according to thestandards for reusable parts.

• The engine’s service life can be extended withoutthe risk of a major catastrophe due to enginefailure.

• The best cost/value relationship per hour ofextended life can be attained.

After Failure Overhaul

If a major engine failure occurs and the enginemust be removed, many options are available. Anoverhaul should be performed if the engine block orthe crankshaft needs to be repaired.

If the engine block is repairable and/or the crankshaftis repairable, the overhaul cost should be between 40percent and 50 percent of the cost of a new enginewith a similar exchange core.

This lower cost can be attributed to three aspects:

• Specially designed Caterpillar engine features

• Caterpillar dealer exchange components

• Caterpillar Inc. remanufactured exchangecomponents

Overhaul RecommendationTo minimize downtime, Caterpillar Inc. recommendsa scheduled engine overhaul by your Caterpillardealer before the engine fails. This will provide youwith the best cost/value relationship.

Note: Overhaul programs vary according to theengine application and according to the dealer thatperforms the overhaul. Consult your Caterpillardealer for specific information about the availableoverhaul programs and about overhaul services forextending the engine life.

If an overhaul is performed without overhaul servicefrom your Caterpillar dealer, be aware of the followingmaintenance recommendations.

Rebuild or Exchange

Cylinder Head Assembly, Oil Pump, and FuelTransfer Pump

These components should be inspected according tothe instructions that are found in various Caterpillarreusability publications. The Special Publication,SEBF8029 lists the reusability publications that areneeded for inspecting the engine parts.

If the parts comply with the established inspectionspecifications that are expressed in the reusableparts guideline, the parts should be reused.

Parts that are not within the established inspectionspecifications should be dealt with in one of thefollowing manners:

• Salvaging

• Repairing

• Replacing

Using out-of-spec parts can result in the followingproblems:

• Unscheduled downtime

• Costly repairs

• Damage to other engine parts

• Reduced engine efficiency


Overhaul Considerations

• Increased fuel consumption

Reduced engine efficiency and increased fuelconsumption translates into higher operating costs.Therefore, Caterpillar Inc. recommends repairingout-of-spec parts or replacing out-of-spec parts.

Inspection and/or Replacement

Crankshaft Bearings and Crankshaft Seals

The following components may not last until thesecond overhaul.

• Thrust bearings

• Main bearings

• Rod bearings

• Crankshaft seals

Caterpillar Inc. recommends the installation of newparts at each overhaul period.

Inspect these parts while the engine is disassembledfor an overhaul.

Inspect the crankshaft for any of the followingconditions:

• Deflection

• Damage to the journals

• Bearing material that has seized to the journals

Check the journal taper and the profile of thecrankshaft journals. Check these components byinterpreting the wear patterns on the followingcomponents:

• Rod bearing

• Main bearings

Inspect the camshaft for damage to the journals andto the lobes.

Note: If the camshaft is removed for any reason, usethe magnetic particle inspection process to check forcracks in the camshaft.

Inspect the following components for signs of wear orfor signs of scuffing:

• Camshaft bearings

• Lifters

Caterpillar Inc. recommends replacing the crankshaftvibration damper.

Oil Cooler Core

During an overhaul, Caterpillar Inc. recommends theremoval of the oil cooler core. Clean the oil coolercore. Then, pressure test the oil cooler core.

NOTICEDo not use caustic cleaners to clean the core.

Caustic cleaners can attack the internal metals of thecore and cause leakage.

Note: Use this cleaning procedure to clean the oilcooler core.

1. Remove the oil cooler core.

2. Remove any debris from the oil cooler core. Toremove debris from the oil cooler core, turn the oilcooler core onto one end.

3. Flush the oil cooler core internally with cleaner inorder to loosen foreign substances. This will alsohelp to remove oil from the oil cooler core.

Note: Caterpillar Inc. recommends the use ofHydrosolv Liquid Cleaners. Table 15 lists theHydrosolv Liquid Cleaners that are available fromyour Caterpillar dealer.

4. Use steam to clean the oil cooler core. Thisremoves any remaining residue from the cleaner.Flush the fins of the oil cooler core. Remove anyother trapped debris.

5. Wash the oil cooler core with hot, soapy water.Rinse the oil cooler core thoroughly with cleanwater.

96 SEBU8180-01Maintenance SectionRadiator - Clean




6. Dry the oil cooler core with compressed air. Directthe air in the reverse direction of the normal flow.

7. Inspect the components in order to ensurecleanliness. The oil cooler core should bepressure tested. Repair the oil cooler core, ifnecessary. Install the oil cooler core.

For more information about cleaning the cores,consult your Caterpillar dealer.

Obtain Coolant Analysis

The concentration of supplemental coolant additive(SCA) should be checked regularly with test kitsor with S·O·S Coolant Analysis (Level 1). Furthercoolant analysis is recommended when the engineis overhauled.

For example, considerable deposits are found in thewater jacket areas on the external cooling system, butthe concentrations of coolant additives were carefullymaintained. The coolant water probably containedminerals that were deposited on the engine over time.

A coolant analysis can be conducted in order to verifythe condition of the water that is being used in thecooling system. A full water analysis can be obtainedby consulting your local water utility company oran agricultural agent. Private laboratories are alsoavailable for water analysis.

Caterpillar Inc. recommends an S·O·S CoolantAnalysis (Level 2).


An S·O·S Coolant Analysis (Level 2) is acomprehensive coolant analysis which completelyanalyzes the coolant and the effects on the coolingsystem. An S·O·S Coolant Analysis (Level 2) providesthe following information:

• Complete S·O·S Coolant Analysis (Level 1)

• Visual inspection of properties

• Identification of metal corrosion

• Identification of contaminants

• Identification of built up impurities (corrosion andscale)

S·O·S Coolant Analysis (Level 2) provides a report ofthe results of both the analysis and the maintenancerecommendations.

For more information about coolant analysis, seeyour Caterpillar dealer.

i02559063

Radiator - CleanSMCS Code: 1353-070

Note: Adjust the frequency of cleaning according tothe effects of the operating environment.

Inspect the radiator for these items: damaged fins,corrosion, dirt, grease, insects, leaves, oil, and otherdebris. Clean the radiator, if necessary.



The maximum air pressure for cleaning purposesmust be reduced to 205 kPa (30 psi) when the airnozzle is deadheaded.

Pressurized air is the preferred method for removingloose debris. Direct the air in the opposite directionof the fan’s air flow. Hold the nozzle approximately6 mm (0.25 inch) away from the fins. Slowly move theair nozzle in a direction that is parallel with the tubes.This will remove debris that is between the tubes.

Pressurized water may also be used for cleaning.The maximum water pressure for cleaning purposesmust be less than 275 kPa (40 psi). Use pressurizedwater in order to soften mud. Clean the core fromboth sides.

Use a degreaser and steam for removal of oil andgrease. Clean both sides of the core. Wash the corewith detergent and hot water. Thoroughly rinse thecore with clean water.


Severe Service Application - Check

After cleaning, start the engine and accelerate theengine to high idle rpm. This will help in the removalof debris and drying of the core. Stop the engine.Use a light bulb behind the core in order to inspectthe core for cleanliness. Repeat the cleaning, ifnecessary.

Inspect the fins for damage. Bent fins may be openedwith a “comb”. Inspect these items for good condition:welds, mounting brackets, air lines, connections,clamps, and seals. Make repairs, if necessary.

For more detailed information on cleaning andinspection, refer to Special Publication, SEBD0518,“Know Your Cooling System”.

i00151038

Severe Service Application -CheckSMCS Code: 1000-535

Severe service is an application of an engine thatexceeds current published standards for that engine.Caterpillar maintains standards for the followingengine parameters:

• Performance (power range, speed range, and fuelconsumption)

• Fuel quality

• Altitude range

• Maintenance intervals

• Oil selection and maintenance

• Coolant selection and maintenance

• Environmental qualities

• Installation

Refer to the standards for the engine or consult withyour Caterpillar dealer in order to determine if theengine is operating within the defined parameters.

Severe service operation can accelerate componentwear. Engines that operate under severe conditionsmay need more frequent maintenance intervals inorder to ensure maximum reliability and retention offull service life.

Due to individual applications, it is not possible toidentify all of the factors which can contribute tosevere service operation. Consult your Caterpillardealer for the unique maintenance that is necessaryfor the engine.

The operating environment, improper operatingprocedures and improper maintenance procedurescan be factors which contribute to severe serviceconditions.

Environmental FactorsAmbient temperatures – The engine may beexposed to extended operation in extremelycold environments or hot environments. Valvecomponents can be damaged by carbon buildup ifthe engine is frequently started and stopped in verycold temperatures. Extremely hot inlet air reducesengine performance.

Air Quality – The engine may be exposed toextended operation in an environment that is dirtyor dusty, unless the equipment is cleaned regularly.Mud, dirt and dust can encase components.Maintenance can be very difficult. The buildup cancontain corrosive chemicals.

Buildup – Compounds, elements, corrosivechemicals and salt can damage some components.

Altitude – Problems can arise when the engine isoperated at altitudes that are higher than the intendedsettings for that application. Necessary adjustmentsshould be made.

Improper Operating Procedures• Extended operation at low idle

• Frequent hot shutdowns

• Operating at excessive loads

• Operating at excessive speeds

• Operating outside the intended application

Improper Maintenance Procedures• Extending the maintenance intervals

• Failure to use recommended fuel, lubricants andcoolant/antifreeze

i02348493

Starting Motor - InspectSMCS Code: 1451-040; 1453-040

Caterpillar recommends a scheduled inspection ofthe starting motor. If the starting motor fails, theengine may not start in an emergency situation.

98 SEBU8180-01Maintenance SectionTurbocharger - Inspect

Check the starting motor for correct operation. Checkthe electrical connections and clean the electricalconnections. Refer to the Systems Operation, Testingand Adjusting Manual, “Electric Starting System -Test” for more information on the checking procedureand for specifications or consult your Caterpillardealer for assistance.

i02724929

Turbocharger - InspectSMCS Code: 1052-040; 1052

A regular visual inspection of the turbocharger isrecommended. If the turbocharger fails during engineoperation, damage to the turbocharger compressorwheel and/or to the engine may occur. Damage to theturbocharger compressor wheel can cause additionaldamage to the pistons, the valves, and the cylinderhead.

NOTICETurbocharger bearing failures can cause large quanti-ties of oil to enter the air intake and exhaust systems.Loss of engine lubricant can result in serious enginedamage.

Minor leakage of oil into a turbocharger under extend-ed low idle operation should not cause problems aslong as a turbocharger bearing failure has not oc-cured.

When a turbocharger bearing failure is accompaniedby a significant engine performance loss (exhaustsmoke or engine rpm up at no load), do not continueengine operation until the turbocharger is renewed.

A visual inspection of the turbocharger can minimizeunscheduled downtime. A visual inspection of theturbocharger can also reduce the chance for potentialdamage to other engine parts.

Removal and InstallationNote: The turbochargers that are supplied arenonserviceable.

For options regarding the removal, installation,and replacement, consult your Carerpillar dealer.Refer to the Disassembly and Assembly Manual,“Turbocharger - Remove and Turbocharger - Install”for further information.

Inspecting

NOTICEThe compressor housing for the turbocharger mustnot be removed from the turbocharger for inspectionor removed for the cleaning of the compressor.

1. Remove the pipe from the turbocharger exhaustoutlet and remove the air intake pipe to theturbocharger. Visually inspect the piping for thepresence of oil. Clean the interior of the pipesin order to prevent dirt from entering duringreassembly.

2. Check for obvious heat discoloration of theturbocharger. Check for any loose bolts or anymissing bolts. Check for damage to the oil supplyline and the oil drain line. Check for cracks inthe housing of the turbocharger. Ensure that thecompressor wheel can rotate freely.

3. Check for the presence of oil. If oil is leaking fromthe back side of the compressor wheel, there is apossibility of a failed turbocharger oil seal.

The presence of oil may be the result of extendedengine operation at low idle. The presence of oilmay also be the result of a restriction of the linefor the intake air (clogged air filters), which causesthe turbocharger to slobber.

4. Inspect the bore of the housing of the turbineoutlet for corrosion.

5. Fasten the air intake pipe and the exhaust outletpipe to the turbocharger housing. Ensure that allclamps are installed correctly and that all clampsare tightened securely.

Inspection


Arrangement for the V-belts

To maximize the engine performance, inspect thebelts for wear and for cracking. Replace belts that areworn or damaged.

For applications that require multiple drive belts,replace the belts in matched sets. Replacing onlyone belt of a matched set will cause the new belt tocarry more load because the older belt is stretched.The additional load on the new belt could cause thenew belt to break.

If the belts are too loose, vibration causesunnecessary wear on the belts and pulleys. Loosebelts may slip enough to cause overheating.

To accurately check the belt tension, install144-0235 Belt Tension Gauge.

g01003936Illustration 65Typical example(1) Gauge

Fit the gauge (1) at the center of the longest freelength and check the tension. The correct tension fora used belt is 355 N (79.8 lb). If the tension of thebelt is below 250 N (56 lb) adjust the belt to 355 N(79.8 lb).

Note: The correct tension for a new belt or new beltsis 535 N (120 lb). A higher tension is required inorder to compensate for the stretch that is in a newbelt. Only use the higher tension on a belt that hasnot been used. A used belt is a belt that has been inoperation for 30 minutes or a longer period of time.

If twin belts are installed, check and adjust thetension on both belts.

Adjustment

Walk-Around InspectionSMCS Code: 1000-040

Inspect the Engine for Leaks andfor Loose ConnectionsA walk-around inspection should only take a fewminutes. When the time is taken to perform thesechecks, costly repairs and accidents can be avoided.

For maximum engine service life, make a thoroughinspection of the engine compartment before startingthe engine. Look for items such as oil leaks or coolantleaks, loose bolts, worn belts, loose connections andtrash buildup. Make repairs, as needed:

• The guards must be in the correct place. Repairdamaged guards or replace missing guards.

• Wipe all caps and plugs before the engine isserviced in order to reduce the chance of systemcontamination.

NOTICEFor any type of leak (coolant, lube, or fuel) clean up thefluid. If leaking is observed, find the source and correctthe leak. If leaking is suspected, check the fluid levelsmore often than recommended until the leak is foundor fixed, or until the suspicion of a leak is proved to beunwarranted.

NOTICEAccumulated grease and/or oil on an engine is a firehazard. Remove the accumulated grease and oil. Re-fer to this Operation and Maintenance Manual, “En-gine - Clean” for more information.

• Ensure that the cooling system hoses are correctlyclamped and that the cooling system hoses aretight. Check for leaks. Check the condition of allpipes.

• Inspect the water pump for coolant leaks.

Note: The water pump seal is lubricated by thecoolant in the cooling system. It is normal for a smallamount of leakage to occur as the engine cools downand the parts contract.

Excessive coolant leakage may indicate the need toreplace the water pump. Remove the water pump.Refer to Disassembly and Assembly , “Water Pump -Remove and Install”. For more information, consultyour Caterpillar dealer.

• Inspect the lubrication system for leaks at the frontcrankshaft seal, the rear crankshaft seal, the oilpan, the oil filters and the rocker cover.

• Inspect the piping for the air intake system and theelbows for cracks and for loose clamps. Ensurethat hoses and tubes are not contacting otherhoses, tubes, wiring harnesses, etc.

• Ensure that the areas around the rotating parts areclear.

• Inspect the alternator belts and any accessorydrive belts for cracks, breaks or other damage.

• Inspect the wiring harness for damage.

Belts for multiple groove pulleys must be replaced asmatched sets. If only one belt is replaced, the belt willcarry more load than the belts that are not replaced.The older belts are stretched. The additional load onthe new belt could cause the belt to break.

High Pressure Fuel Lines

Maintenance RecordsSMCS Code: 1000

Caterpillar Inc. recommends the retention of accuratemaintenance records. Accurate maintenance recordscan be used for the following purposes:

• Determine operating costs.

• Establish maintenance schedules for other enginesthat are operated in the same environment.

• Show compliance with the required maintenancepractices and maintenance intervals.

Maintenance records can be used for a variety ofother business decisions that are related to enginemaintenance.

Maintenance records are a key element of amaintenance program that is well managed. Accuratemaintenance records can help your Caterpillar dealerto fine tune the recommended maintenance intervalsin order to meet the specific operating situation. Thisshould result in a lower engine operating cost.

Records should be kept for the following items:

Fuel Consumption – A record of fuel consumptionis essential in order to determine when the loadsensitive components should be inspected orrepaired. Fuel consumption also determines overhaulintervals.

Service Hours – A record of service hours isessential to determine when the speed sensitivecomponents should be inspected or repaired.

Documents – These items should be easy toobtain, and these items should be kept in the enginehistory file. All of the documents should show thisinformation: date, service hours, fuel consumption,unit number, and engine serial number. The followingtypes of documents should be kept as proof ofmaintenance or repair for warranty:
