Hydraulic hoses and tubing must beinspected on a daily basis for leaks, cuts,abrasions, damage and improperclearance along any mounting frame forhidden damage before the unit is put intoservice. Replace damaged hoses or hosesyou suspect are damaged before thesystem is returned to service! Hoses mustbe replaced every two years. Failure toproperly inspect and maintain the systemmay result in serious injury.
Hydraulic systems are hot. DO NOTTOUCH! Serious personal injury mayresult from hot oil. When you havecompleted working on the hydraulicsystem, thoroughly clean any spilled oilfrom the equipment. Do not spill anyhydraulic fluids on the ground. Clean anyhydraulic fluids from your skin as soon asyou have completed maintenance andrepairs. Dispose of used oil and systemfilters as required by law.
Use correct hoses, fittings, and adapterswith the correct SAE rating whenreplacing hoses to prevent possibleserious injury. Always replace hoses,fittings, and adapters with replacementsthat have a proper, suitable, workingpressure rating. Replacement hoses mustbe of the correct length and must complywith the hose manufacturer’s andOilgear’s installation guidelines andrecommendations.
Hydraulic hoses have the SAE ratingsmarked on the hose to assist you inselecting the correct hose. The same manu-facturer must supply any replacementhydraulic hoses and fitting assemblies. Asan example: Brand “X” hose and brand “Y”fitting will not normally be compatible. No“Twist” is allowed in the hydraulic hoses.“Twist” may result in premature hosefailure. This can cause serious injury.Please contact Oilgear for assistance whenrequired.
Hydraulic cylinders can be holding afunction in a certain position whenthepump is OFF. An example of this is afunction being held in the lift or partial liftposition by the cylinders. If a hydraulicline is removed or the hydraulic circuits orcontrols are being worked on, gravity mayallow the function being held in position todrop. All workers and personnel mustremain clear of these areas when workingon or operating the hydraulic system.Block and secure all devices andfunctions which apply before beginningwork or operation. Failure to comply withthis can result in serious injury or death.
Any hydraulic pipe which is replaced mustconform to SAE J1065 specifications. Ifincorrect hydraulic pipe is installed, thehydraulic system may fail, causingserious injury. Damaged or leakingfittings, pipes or hoses must be replacedbefore the system is returned to service.
DO NOT heat hydraulic pipe. The carboncontent of this steel tube is such that ifheated for bending, and either water or airquenched, the pipe may lose its ductilityand thereby be subject to failure underhigh-pressure conditions. Serious injurycan result. Damaged or leaking pipes mustbe replaced before the system is returnedto service. Please contact Oilgear if yourequire assistance or have questions.
All hydraulic pressure must be relievedfrom the hydraulic system prior to removingany components from the system. Torelieve the hydraulic pressure from thehydraulic system, turn off the motor andoperate the control panel with the key in theON position. Failure to comply can result inserious injury. If you have any questionsconcerning relieving the hydraulic pressurefrom the system, please contact Oilgear.

Installing an incorrect test gaugecould result in serious injury if the gaugefails. Use properly rated hydraulic hosesto allow the test gauge to be read awayfrom moving parts and functions.
Increasing hydraulic pressure beyond therecommendations may result in seriousdamage to the pump and system orserious personal injury and may void theOilgear Warranty. If you have questionsconcerning hydraulic pressures or testingprocedures, please contact Oilgear beforeattempting the test procedures or makingadjustments.
An Oilgear pump or pump control mustnot be modified in any way withoutauthorization from Oilgear. Modificationsmay not comply with safety standards,including ANSI safety standards, and mayresult in serious personal injury. Pleasecontact Oilgear if you require assistance.
DO NOT enter under hydraulic supportedequipment unless they are fully supportedor blocked. Failure to follow this procedurecan result in serious injury or death.
Any Oilgear pump safety decals must bereplaced anytime they are damaged,missing, or cannot be read clearly. Failureto have proper decals in place can resultin serious injury or death. (If you requiresafety decals, please contact Oilgear forreplacement safety decals, at no charge.)
Be sure everyone is clear of the areaaround the hydraulic system beforeoperating after servicing. Remain attentiveat all times when operating to check yourwork until you are completely sure it issafe to return to service. Failure to heedthis warning may result in seriouspersonal injury or death.
Wear the proper protective clothing whenoperating, servicing or maintaining thehydraulic system or the Oilgear pump. Wearthe correct protective gear, safety glasses,gloves, and safety shoes. Serious injurycan result without proper protective gear.

PREPARATION AND INSTALLATION
MOUNTING
Pump Without Reservoir - The pump can bemounted in any position. But, the recommendedmounting position is with the drive shaft on ahorizontal plane and the case drain port 1 on thetop side. Secure the pump to a rigid mountingsurface. Refer to the referenced Oilgear PipingInformation Bulletin 90011.
Pump With Reservoir - These pumps are usuallyfully piped and equipped. It may be necessary toconnect to a super-charge circuit when used.Mount reservoir on level foundation with thereservoir bottom at least 6 inches (152 mm) abovefloor level to facilitate fluid changes.
PIPING AND FITTINGS
Refer to the referenced Oilgear Piping InformationBulletin 90011 and individual circuit diagram beforeconnecting the pump to the system. Inlet velocitymust not exceed 5 fps (1,5 mps). Inlet should beunrestricted and have a minimum of fittings.
DO NOT use an inlet strainer.
Arrange line from “case drain” so the case remainsfull of fluid (non-siphoning). Case pressure must beless than 25 psi (1,7 bar). For higher casepressures and the special shaft seals required,contact our Customer Service. Each drain linemust be a separate line, unrestricted, full sized andconnected directly to the reservoir below the lowestfluid level. Make provisions for opening this linewithout draining (siphoning) reservoir.
Running the pump in NEUTRAL position(zero delivery) for extended periodswithout a supercharge circuit can damagethe pump. The system and pump must beprotected against overloads by separatehigh-pressure relief valves. Install bleedvalve(s) at the highest point(s) in system.
POWER
Power is required in proportion to volume andpressure used. Motor size recommendations forspecific applications can be obtained from TheOilgear Company. Standard low starting torquemotors are suitable for most applications.
DO NOT start or stop unit under loadunless system is approved by Oilgear. Itmay be necessary to provide deliverybypass in some circuits.
DRIVE
Verify rotation direction plate on the pump's housing.Clockwise pumps must be driven clockwise andcounterclockwise pumps must be drivencounterclockwise. Use direct drive coupling. Sizeand install coupling per manufacturer's instructions.
DO NOT drive the coupling onto the pumpdrive shaft. If it is too tight, it may benecessary to heat coupling for installation.Refer to manufacturer's instructions.
Misalignment of pump shaft to driver's shaft shouldnot exceed 0.005 inches (0,13 mm) Total IndicatorReadout (TIR) in any plane.

FILTRATION
Keep the fluid clean at all times to ensure long lifefrom your hydraulic system. Refer to the referencedOilgear Filtration Recommendations bulletin 90007and Oilgear Contamination Evaluation GuideBulletin 90004. Oilgear recommends use of a filterin the pressure or return line. Replace filterelement(s) when the filter condition indicatorreaches change area at normal fluid temperature.Drain and thoroughly clean filter case. Usereplacement element(s) of same beta 10 ratio(normally a ratio of 4 with hydraulic oils).
FLUID COOLING
When the pump is operated continuously at therated pressure or frequently at peak load, auxiliary cooling of the fluid may be necessary. Fluidtemperature should not exceed limits specified inthe referenced Oilgear Fluid RecommendationsBulletin 90000.
AIR BREATHER
On most installations, an air breather is mountedon top of fluid reservoir. It is important for thebreather to be the adequate size to allow air flow inand out of reservoir as fluid level changes. Keepthe breather case filled to the “fluid level” mark.About once every six months, remove cover, washscreen in solvent and allow screen to dry, cleanand refill case to level mark and install screen.Refer to the manufacturer's recommendations.
FLUID, FILLING AND STARTING RECOMMENDATIONS
Refer to instruction plate on the unit, reservoir,machine and/or reference, fluid recommendationsbulletin. Fire resistant fluids and phosphate esterfluids can be used in accordance with fluidmanufacturer's recommendations.
1. Pump all fluid into reservoir through a clean(beta 10 ratio of 4 or more) filter. Fill reservoirto, but not above, “high level” mark on the sightgauge.
2. Remove case drain line and fill pump casewith hydraulic fluid.
3. Turn drive shaft a few times by hand with aspanner wrench to make sure parts rotate.
Table 1. Torque to Turn Shaft
With pump under “no load” or with pump control atNEUTRAL:
4. Turn drive unit ON and OFF several timesbefore allowing pump to reach full speed. Thesystem can usually be filled by running thepump and operating the control.
5. The fluid level in the reservoir should decrease.Stop the pump. DO NOT allow the fluid level togo beyond the “low level.” If the level reachesthe “low level” mark, add fluid and repeat step.
With differential (cylinder) systems, the fluidmust not be above “high level” when theram is retracted or below “low level” whenextended. Bleed air from the system byloosening connections or opening petcocksat the highest point in the system. Closeconnections or petcocks tightly when solidstream of fluid appears.

PRINCIPLE OF OPERATIONThe illustrations show the pump driven clockwise(right hand) from the top (plan) view.
Figure 2. Cut-a-way of a Typical “PVWJ” Pump with Typical Control
Position B, Pump During Full Delivery FROM PORT B - Figure 3
Rotating the drive shaft (301) clockwise turns thesplined cylinder, which contains the pumpingpistons (102). When the cylinder rotates, thepistons move in and out within their bores as theshoes ride against the angled (C) swashblock(201).
As the cylinder rotates, the individual piston boresare connected, alternately, to the crescent shapedupper (port A) and lower (port B) in the valve plate.While connected to the upper side (suction) port A,each piston moves outward OUT, drawing fluidfrom port A into the piston bore until its outermoststroke (D) is reached. At this point, the piston borepasses from the upper crescent port A to the lowercrescent port B.
While rotating across the lower crescent, eachpiston moves across the angled swashblock faceand then each piston is forced inward IN. Eachpiston then displaces fluid through the lowercrescent to port B until its innermost stroke (D) isreached. At this point, the piston bore passes fromthe lower to the upper crescent again and the cycleis repeated.

Position B/2, Pump During One Half Delivery FROM PORT B - Figure 4
This illustration shows that the angle (E) of theswashblock determines the length of the pistonstroke (F), (the difference between outermost andinnermost position) which determines the amountof delivery from the pump. In this case, the strokeangle (E) is one-half of the stroke, which means thepiston stroke is one-half and the pump delivery isone-half.
Position N, Pump In Neutral, No Stroke, No Delivery - Figure 5
Neutral position results when the controlcenters the swashblock. The swashblockangle (G) is now zero and swashblock face isparallel to the cylinder face. There is noinward or outward motion of the pump pistonsas piston shoes rotate around the swashblockface. With no inward and outward motion orno stroke (H), NEUTRAL no fluid is beingdisplaced from the piston bores to thecrescents in the valve plate and there is nodelivery from pump ports.
Illustration reference numbers match thepart item number in the parts list.

TESTING AND ADJUSTING
PISTON PUMP
To check for a worn piston pump, make a leakmeasurement test from the case drain while thepump is under pressure. After the unit is warm,either install a flow meter in the drain line or havethe flow from the drain line directed into a largecontainer or reservoir. The pump case must remainfull of fluid during this test.
Shut the pump OFF and release pressurefrom the system before disassemblingcomponents. Failure to comply with theseinstructions could result in personal injuryor death. Blocking the pressure linebetween the pump and the system (orpump) high-pressure relief valve willresult in damage and could result inserious personal injury.
With an accurate high-pressure gauge in thepressure line, start the pump and stall (or block)output device to raise system pressure tomaximum (as set by system relief valve). Read themeasurement on the flow meter or time andmeasure the case drain flow used to fill a knownsize container and calculate the flow rate in termsof cubic inches per minute (cipm). The leakageshould conform to Table 4.
DO NOT run a pump on stroke against ablocked output unless it is protected by ahigh-pressure relief valve and then run nolonger than necessary to check slip. Limitdischarge to prevent dropping reservoirfluid below low level.
Increasing shaft speed or a decrease influid viscosity will increase leakage.Manually or mechanically de-stroking thepump has a negligible effect on leakage.
Additional leakage indicates wear, butdoes not become critical until it impairsperformance.
If testing a unit with a pressurecompensator control, make sure thecompensator setting is at least 500 psiabove the pump outlet pressure to assurethe pump is at full stroke.

VALVE PLATE GROUP
Inspect the valve plate (401) surface which mateswith the cylinder barrel (101) for excessive wear orscoring. Remove minor defects by lightly stoningthe surface with a hard stone which is flat to within0.001 inches (0,025 mm).
Be sure to stone lightly. Any excessivestoning will remove the hardened surface.If wear or damage is extensive, replace thevalve plate.
ROTATING GROUP
Inspect cylinder barrel (101) piston bores and theface which mate with the valve plate for wear andscoring. Remove minor defects on the face bylightly stoning or lapping the surface.
Inspect the cylinder bearing (202) for damage andreplace if necessary. Check all piston and shoeassemblies (102) to be sure they ride properly onthe swashblock.
Be sure to stone lightly. Any excessivestoning will remove the hardened surface.If wear or damage is extensive and defectscannot be removed, replace the cylinderbarrel.
See Figure 7. Check each shoe face for nicks andscratches, and the shoe for smooth pivot action onthe piston.
If one or more piston/shoe assembly needsto be replaced, replace all the piston/shoeassemblies. When installing new piston/shoe assemblies or the rotating group,make sure the pistons move freely in theirrespective bores.
Figure 7. Piston and Shoe Inspection
(A) All shoes must be equal within 0.001 inches(0,025 mm) at this dimension.
(B) All shoe faces must be free of nicks.
End play should not to exceed 0.003inches (0,076 mm) when new or 0.006inches (0,152 mm) when worn.
SWASHBLOCK GROUP
Inspect the swashblock (201) for wear and scoring.If defects are minor, stone the swashblock lightly. Ifdamage is extensive, replace the swashblock.
Check the small hole in the face of theswashblock. The hole provides “porting” for thehydrostatic balance fluid of the piston/shoeassembly to be channeled through the swashblockto the face of the saddle bearing, providingpressure lubrication.
Compare the saddle bearing (204) thickness in aworn area to thickness in an unworn area. Replacesaddle bearings if the difference is greater than0.015 inches (0,4 mm).
Check the mating surface of swashblock for cracksor excessive wear. The swashblock movement inthe saddle bearings must be smooth. Replace ifnecessary.
Be sure to stone lightly. Any excessivestoning will remove the hardened surface.If wear or damage is extensive and defectscannot be removed, replace if necessaryor if you suspect them of being bad.

AFTER SALES SERVICESAt Oilgear we build products to last. It is the natureof this type of machinery to require propermaintenance regardless of the care we put intomanufacturing. Oilgear has several serviceprograms in place to help you.
STAY-ON-STREAM SERVICE
By signing up for Oilgear's Stay-On-Streamprogram, you can prepare for problems before theyhappen. Certain field tests such as fluid testing,slip testing and electronic profile recordingcomparisons can be performed by our field servicepeople or your own factory trained personnel.These tests can indicate problems before theybecome “down-time” difficulties.
SERVICE SCHOOLS
Oilgear conducts training to train your maintenancepersonnel. “General” hydraulic or electronictraining is conducted at our Milwaukee, Wisconsinplant on a regular basis. “Custom” training,specifically addressing your particular hydraulicand electro-hydraulic equipment, can be conductedat your facilities.
SPARE PARTS AVAILABILITY
Prepare for your future needs by stocking Oilgearoriginal factory parts. Having the correct partsand necessary skills “in-plant” enables you tominimize “down-time.” Oilgear has developedparts kits to cover likely future needs. OilgearField Service Technicians are also ready to assistyou and your maintenance people in trouble-shooting and repairing equipment.
