removes the windup in the drive line and allows for a greater clearance on the thrust end of the U-joint.
Because of the U-joint seal's design, there will occasionally be one or more bearing seals of a joint that may
not purge. If any bearing seals do not purge, notify Unit maintenance.
(c)
Drive Shaft Slip Joints. When lubricating spline end of drive shafts, apply grease to spline fitting until
lubricant appears at pressure relief hole. Cover hole with finger and continue adding grease until it appears
at sleeve yoke seal.
(d)
Severe Operating Conditions. When vehicle is operating under severe conditions, lubricate drive shafts
and U-joints every 50 hours.
(3)
ENGINE, TRANSMISSION, HYDRAULIC SYSTEM.
(a)
Transmissions. Operate engine 1 minute at 1,500 RPM, then idle until transmission reaches normal
operating temperature. With engine idling, check transmission dipstick. If oil level is on or below LOW line,
add oil. Approximately 1 qt. (0.9 L) of oil is required to bring oil level from bottom of LOW band to desired
level between LOW and FULL band. See Para 3-6.
(b)
Crankcase. Check oil level with vehicle parked on level ground and the engine off and cool. Do not overfill.

and Para 3-8 for additional information regarding the AOAP for the IHMEE.
After expiration of warranty, active Army units will send an engine oil sample to an AOAP laboratory for analysis every 100
hours of operation or 90 days, whichever occurs first. Reserve and National Guard units will send an oil sample to an AOAP
laboratory for analysis every 100 hours of operation or 180 days, whichever occurs first.
Intervals for sampling as well as draining and refilling lubricants may be changed by an AOAP laboratory.
If AOAP laboratory support is not available, drain and refill crankcase oil every 3,000 mi. (4 800 km) or every 6 months,
whichever comes first; and drain and refill transmission oil every 6,000 mi. (9 700 km) or annually, whichever comes first.
Drain and refill hydraulic reservoir every 6,000 mi. (9 700 km) or annually, whichever comes first.
1
After the engine's initial warranty period, crankcase oil will be changed only when directed by an oil
analysis laboratory. When AOAP laboratory support is not available, change oil and filter element(s) at
prescribed hardtime intervals, 3,000 mi. (4 800 km) or 6 months, whichever occurs first.
2
After the transmission's initial warranty period, transmission oil will be sampled every 90 days or
1,000 mi. (1 600 km), whichever occurs first. Reserve and National Guard units will sample every 180
days or 1,000 mi. (1 600 km), whichever occurs first. Transmission oil will be changed only when
directed by an oil analysis laboratory. When AOAP laboratory support is not available, change oil each
6,000 mi. (9 600 km) or 12 months, whichever occurs first.
3
Hydraulic reservoir oil will be sampled every 12 months. Oil will be changed only when directed by an
oil analysis laboratory. When AOAP laboratory support is not available, change oil every 6,000 mi.
(9 600 km) or 12 months, whichever occurs first.
4
The lower ball joints should be given 10-12 strokes with a grease gun through existing grease fitting.
(4) OILCAN POINTS. Every 1,000 mi. (1 600 km) or monthly; lubricate doors, side panels and engine cover hinges,
locks, mirror swivels, and latches.
(5)
CV JOINTS. Only 2 fittings per wheel should be lubricated.
(6)
BACKHOE. The backhoe must be fully extended and lowered to the ground before lubrication.
