NOTES:
1.
ARMY OIL ANALYSIS PROGRAM (AOAP).
For Active Army units, obtain samples from engine
and automatic transmission every 500 miles
(805 km) of operation or 60 days (whichever comes
first). Reserve and National Guard activities will use
500 miles (805 km) or 120 days as the prescribed
sample intervals. Reserve and National Guard
equipment in frequent use during active training
period will adhere to the schedule for Active Army
units. As a minimum, one sample from each item of
equipment will be submitted for each units’ two
week active training period. Send these samples to
the nearest AOAP laboratory. Refer to TB 43-0210 for
sampling instructions. When or if AOAP laboratory
support is unavailable, hard time intervals will apply.
NOTE
l
Do not hold ON samples. Submit oil
samples as soon as they have been taken.
l
Seasonal oil changes will be made due to
expected temperatures (see Key).
2.
FOR OPERATlON OF EQUIPMENT IN
PROTRACTED COLD TEMPERATURES BELOW
-10°F (-23%).
Remove lubricants prescribed in
Key for temperatures above -10°F (-23%).
Relubricate with lubricants specified in Key for
temperatures below -10°F (-23%). If OEA lubricant
is required to meet the temperature ranges
prescribed in the Key, OEA lubricant is to be used in
place of OE/HDO-10 lubricant for all temperature
ranges where OE/HDO-10 Is specified in the Key.
3.
OIL CAN POINTS.
Each 2500 miles
(4023 km), lubricate transmission remote control
linkage, pivot pins, sliding surfaces, accelerator
linkage, door hinge pins, cab latch, pedal-to-brake
valve linkage, butterfly-type hood hinge, and all
exposed adjusting threads with OE/HDO-10.
NOTE
When OEA oil is used, oil level should be
checked more often.
4.
ENGINE OIL LEVEL HOT OR COLD CHECK.
Cold engine, oil level should be at “H” (high) mark
on dipstick. Hot engine, oil level must be between
“H” (high) and “L” (low) marks on dipstick (allow to
set five minutes before checking).
5.
ENGINE CRANKCASE.
Oil is to be changed
each time an engine oil change is directed by AOAP
laboratory. When AOAP laboratory support is not
available, change oil every 1000 miles (1609 km).
Drain when lubricant is warm.
6.
ENGINE FULL FLOW OIL FILTER.
Filter
element is to be replaced each time an engine oil
change is directed by AOAP laboratory. After
installing new filter element, fill crankcase, operate
engine for five minutes, check housing for leaks,
check crankcase oil level, and bring to “H” (high)
mark on dipstick. When AOAP support is not
available, install new filter element each 1000 miles
(1609 km).
7.
ENGINE AUXILIARY OIL FILTER.
Filter
element is to be replaced each time an engine oil
change is directed by AOAP laboratory. After
installing new filter element, fill crankcase, start
engine, and loosen vent plug in cover. Tighten vent
plug when oil appears at plug. Operate engine for
five minutes, check housing for leaks, check
crankcase oil level, and bring to “H” (high) mark on
dipstick. When AOAP laboratory support is not
available, install new filter element each 1000 miles
(1609 km).
8.
POWER STEERING PUMP FILTER.
Each
10,000 miles (16,090 km), drain power steering
reservoir, remove cover plate, filter element, and
clean inside of reservoir with lint-free cloth. Install
new filter element and replace cover. Fill reservoir to
indicated level or 1½ in. (3.8 cm) below top of filler
neck on reservoir. With engine running, turn wheels
from left to right and continue filling until the proper
level is maintained. When operating in dusty areas,
replace filter element more often.
9.
AIR
CLEANER
STRAINER
(AIR
COMPRESSOR).
Each 2500 miles (4023 km),
remove strainer from air cleaner. Clean strainer, oil
lightly with OE/HDO-30, and install in air cleaner.
When operating under extreme dusty conditions,
service strainer more often.
10.
WATER PUMP AND FAN HUB.
Each 10,000
miles (16,090 km), remove pipe plugs, install
fittings, lubricate with a shot (tablespoon full) of
GAA, and install pipe plugs.
11.
FORWARD-REAR AND REAR-REAR AXLE
WHEEL BEARINGS.
Each 10,000 miles
(16,090 km), remove wheels, clean and inspect all
parts, and replace damaged or worn parts. Repack
bearings, assemble, and adjust bearings.
12.
FORWARD-REAR AND REAR-REAR AXLE
BRAKE CHAMBER.
Each 5000 miles (8045 km),
add 2 oz (59 cc) of OE/HDO-10 through air inlet port
at each brake chamber to lubricate seal.
