NOTES

1. INTERVALS

This lubrication instruction has been revised with the Department of Army program to extend intervals

to conserve lubricants. This instruction applies only to vehicles in normal operation. Lubricate more

frequently to compensate for abnormal or extreme conditions, such as high or low temperatures, emersion

in water, or exposure to sand or dust. Lubricants which have become contaminated will be changed

regardless of scheduled intervals. Points requiring lubrication at 3,000 miles (4,827 km) on vehicles not

accumulating 3,000 miles (4,827 km) in a six-month period, will be lubricated at time of semiannual (S)

preventive maintenance service. Points requiring lubrication at 6,000 miles (9,654 km) in a six-month

period will be lubricated at least once a year. Points requiring lubrication at 12,000 miles (19,308 km) will

be lubricated annually. When practicable, lubrication services will be made to coincide with semiannual

preventive maintenance service. For this purpose, a 10-percent variation in specified lubrication point

mileage is permissible.

2. WINCH CABLE

At semiannual service, if cable is not generally used, unwind entire cable. Use a brush to clean, and soak

with new OE/HDO. Wipe off excess, and coat with CW before rewinding cable on drum.

3. GEARCASES

NOTE

When a safe level of lubricant within a gear housing is indicated at

time of scheduled lubrication, the lubricant retaining seal is functional,

even though the seal may indicate questionable leakage. Questionable

leaks that may indicate a defective seal will be subject to frequent

observation as a potential problem area. When seepage or leakage of

lubricant adversely affects the proper function of parts within the area;

e.g., brakes, the retaining seal is non-functional regardless of lubricant

level.

Change gear lubricant only when required by maintenance repair action, or if contaminated by water or

other foreign material. Semiannually, check lubricant for proper level and for contamination. Drain only

when unit is hot after operation. At axle differentials, transfer case, and front winch, check level within

1/2 in. (12.70 mm) of level plug opening. Level in winch end housing is 6-7/8 in. (174.62 mm) below filler

plug. Use the full level plug located on the right side on winch worm housing to check lubrication level.

4. CRANKCASE BREATHER

Check and clean crankcase breather and lines every 6,000 miles (9,654 km) under normal operating

conditions.

5. OIL FILTERS

Oil

filters shall be serviced/cleaned/changed as applicable when:

They are known to be contaminated or clogged.

Service is recommended by AOAP laboratory analysis.

Prescribed hard-time intervals are reached.

6. CRANKCASE

NOTE

Submit oil samples as soon as they have been taken.

AOAP does not do away with seasonal oil changes. Make oil changes as

seasonal temperatures require.

a. Sample oil every 60 days or 1,000 miles (1,609 km). Army Reserve Units will sample oil every

120 days or 1,000 miles (1,609 km). Oil will be changed only when directed by oil analysis laboratory.

To check engine oil level, wait at least one minute after shutting down engine to allow oil to drain into

crankcase. Safe operating level is between ADD and FULL on dipstick. Do not overfill.
