NOTES

INTERVALS

This Lubrication Order (LO) 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 mare frequently to compensate for abnormal or extreme conditions, such as hi h or

law 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) an 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 mode to coincide with

semiannual preventive maintenance service. For this purpose, a lo-percent variation in

specified lubrication point mileage is permissible.

WINCH CABLE

After each day's operation, clean and oil with new OE/HDO. Semiannually, unwind entire

cable, clean, and ail. At semiannual PMCS 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 an drum.

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 far

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.

CRANKCASE BREATHER

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

operating conditions.

MASTER CYLINDER ASSEMBLY

WARNING

Clean master cylinder reservoir filler cap and surroundin

area before removing cap. System contamination can result

in injury to personnel or damage to equipment.

Check or refill fluid level. Check ail level daily, before vehicle operation. Use BFS (MIL-B-

46176). Oil level must be to full line.
