Intervals (on condition or hard time) and related man-hour times are based on normal operation. The man-hour time specified is the time you need to do all the services prescribed for a particular interval. On Condition (OC) oil sample intervals shall be applied unless changed by the Army Oil Analysis Program (AOAP) Laboratory. Change the hard time interval if your lubricants are contaminated or if you are operating the equipment under adverse operating conditions, including longer-than- usual operating hours. The hard time interval may be extended during periods of low activity, If extended, adequate preservation precautions must be taken. Hard time intervals will be applied in the event AOAP laboratory support is not available.

Intervals shown in this lubrication instruction are based on mileage and calendar times. An example of a mileage and calendar lubrication is 3/S, in which 3 stands for 3,000 miles and S stands for semi-annually. The lubrication is to be performed at whichever interval occurs first for the vehicle.

On ancillary equipment, the hours interval is estimated hours of operation, not actual engine hours that appear on the hourmeter.

Dotted arrow points indicate lubrication on both sides of the vehicle or equipment.

CLEANING. Clean fittings before lubricating. Clean parts with dry cleaning solvent (SD) type II or equivalent. Dry before lubricating.

LEVEL OF MAINTENANCE. The lowest level of maintenance authorized to lubricate a point is indicated by one of the following: Operator/Crew (C); and Organizational Maintenance (O).

LUBRICANTS. Lubricant types and operating temperature ranges are given within the key on Cards 2 and 3. When changing or applying lubricants, be sure to follow the recommended temperature ranges for those lubricants.

AFTER FORDING. Lubricate all fittings below fording depth and check submerged gear boxes, engine, and transmission for the presence of water.

AFTER HIGH PRESSURE WASHING. Lubricate all grease fittings and oil can points outside and underneath vehicle.

LOCALIZED VIEW. A reference to the appropriate localized view is given after the lubrication entry in most cases. Localized views begin on Card 14.

NOTES

1. Cold Temperature Operation. When operating equipment in temperatures below 0°F (-18°C), remove lubricants prescribed for temperatures above 0°F (-18°C). Relubricate with lubricants specified for temperatures 0°F to -50” (-18°C to -45°C). Refer to Cards 2 and 3 for lubricant temperature ranges.

2. Crankcase. Check oil level with truck parked on level ground and the engine off and cool. Do not overfill.

3. Change oil every 3,000 miles or semi-annually until expiration of warranty. After expiration of warranty, change oil only when directed by an oil analysis lab or at the above hard time interval if oil lab support is unavailable. For oil analysis, obtain a sample of engine oil every 25 hours of operation or 30 days, whichever comes first. Obtain this sample through the engine dipstick opening for non-A1 vehicles. For LVSA1 series vehicles only, obtain this sample from the engine oil sampling valve. Send this sample to the nearest oil analysis laboratory. See TB 43-0210 for instructions on use of sampling pump as well as the nearest oil lab location. Drain crankcase only when hot after operation. See local view M for drain location and view N for fill location. See view AV for sampling location of non-A1 vehicles and view R for sampling location of LVSA1 series vehicles.

4. Engine Oil Filter. After installing new filter element, fill crankcase, operate engine 5 minutes, and check housing for leaks. Shut down engine, check crankcase oil level, and bring to full mark.

5. Transmission. Operate engine 1 minute at 1,000 RPM, then idle until engine temperature reaches 60-120°F (16-49°C). With engine idling, check transmission dipstick. If oil level is on or below COLD RUN line, add oil. Approximately 1 quart (0.9L) of oil is required to bring oil level from bottom of COLD RUN line to middle of COLD RUN line.

6. Transmission Internal Oil Filter. Change at overhaul.

7. Change oil every 3,000 miles or semi-annually until expiration of warranty. After expiration of warranty, change oil only when directed by an oil analysis lab or at the above hard time interval if oil lab support is unavailable. For oil analysis, obtain a sample of transmission oil every 25 hours of operation or 30 days, whichever comes first. Obtain this sample through the transmission dipstick opening for non-A1 vehicles. For LVSA1 series vehicles only, obtain this sample from the transmission oil sampling valve. Send this sample to the nearest oil analysis laboratory. See TB 43-0210 for instructions on use of sampling pump as well as the nearest oil lab location. See local view AW for sampling location of non-A1 vehicles and view R for sampling location of LVSA1 series vehicles, and see view Q for fill location. See local view S for transmission drain location.

8. Transfer Case. First oil change must be performed between 500 (800 km) and 1,000 (1,600 km) miles thereafter.

9. Axle Differentials. Change lubricant in new or rebuilt axles within 1,000 miles (1,600 km), but no sooner than 500 miles (800 km).

During all lubricant changes, remove metal particles from magnetic drain and filler plugs. Clean the lube pump filter screen in No. 3 axle.

Fill differential housings to a level even with bottom of CHECK and FILL plug hole.

When filling No. 1 and No 3 differentials, add 1 qt. (.91L) of lubricant through fill hole in top of power divider. To fill No. 1 axle power divider, remove lube line at top of power divider.

Coat all axle plugs with Loctite 242 and tighten securely.

CARD 27 of 30

LI 2320-12/9 LO 9-2320-297-12

10. When filling No. 2, 3, and 4 differentialsforthefirsttimeorafteramajor overhaul, fill to bottom of CHECK and FILL plug hole, then raise one end of axle 12 inches (305 mm) to allow lubricant to flow out to wheel bearing. Leave axle raised for five minutes Lower the axle and refill. Raise other end of axle the same way, then lower and refill again.

11. First oil change must be performed between 500 (800 km) and 1,000 (1,600 km) miles thereafter.

12. Purging of Lubricant. When using a grease gun, apply lubricant to the fitting until clean lubricant squeezes out of the part being lubricated.

CAUTION

Rotate universal joint to obtain access to the fitting. Forcing the grease gun onto the fitting can result in broken or damaged fitting.

13. Universal Joints. Use the proper lubricant to purge all four bearing seals of each universal joint. This flushes abrasive contaminants from each bearing and assures that all four bearing are filled properly. Pop the seals. These seals are made to be popped. More than one grease fitting may be installed in a universal joint. Apply grease to one fitting only.

14. If any seals fail to purge, move propeller shaft from side to side while applying gun pressure. This allows greater clearance on thrust end of the bearing that is not purging.

15. By the design of the universal joint seal, there will occasionally be one or more bearing seals of a joint that may not purge. In such cases, seal tension must be released. The procedure for releasing seal tension is as follows:

Loosen bolts holding unpurged bearing assembly. It may be necessary to loosen bearing assembly approximately 1/16-inch (1.587 mm) minimum. If loosening does not result in purging, remove bearing assembly to determine cause of blockage. When you are sure of proper lubrication, run bolts down until bearing plates are flush to yoke races, then back off slightly. Retighten to torque specifications. If present, bend lock tabs against sides of bolt heads to lock bolts in place.

NOTES (Continued)

CAUTION

In cold winter months, activate the slip joint by driving the vehicle. This will cause displacement of the grease before it stiffens. Otherwise the slip joint plug may be forced out due to hydraulic pres- sure.

16. Drive Shaft Slip Joints. When lubricating spline end of propeller shafts, apply grease to spline fitting until lubricant appears at seal.

CAUTION

When pillow block is being relubricated, avoid excessive grease pressure, which may cause damage to the bearing seals.

17. Pillow Block. Lubricate fittings with manual type grease gun. Do not use an air powered type grease gun.

18. Cooling System. Refer to TB 750-651 for use of antifreeze solutions, cleaning compounds, and testing.

19. Front Wheel Bearings. See TM 9-2320-297-20 for bearing removal and installation.

20. Fifth Wheel. Clean and recoat the parts more often when the vehicle is operated in sandy or dusty conditions.

21. Winches. Change oil after the first 10 hours of operation, and every 50 hours thereafter.

22. No. 3 Propeller Shaft is not on MK 16.

23. Engine Oil. First engine oil change must be performed between 500 (800 km) and 1,000 (1,600 km) miles.

24. Must be performed at Direct Support, Third Echelon level.

25. Inspect sides of stabilizer beams and extension booms for scuff marks. If scuff marks are present, lubricate those points also.

26. The 50 hour interval is based on actual crane operating hours. The hours can be tracked by the operator and recorded in the logbook. The crane should be lubricated on a monthly or 50 actual operating hour interval, whichever comes first. Crane must be fully unstowed to properly lubricate.
