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