0090 00
NOTE
If AOAP laboratory support is not available, notify unit maintenance to drain oil and change
filter element/gasket every 1,500 miles or semi-annually. The hard time interval may be
shortened if equipment is operated under adverse conditions.
Engine and transmission filters need to be replaced every 150 hours/1,500 miles or
semi-annually, even when following AOAP procedures.
Sampling Procedures:
1.
Perform DAILY operation checks and services.
NOTE
DO NOT ADD OIL immediately prior to taking oil samples. When operation checks and
services indicate the need to replenish oil levels, WAIT until after taking samples. New oil
added immediately prior to taking samples or before prolonged operation of components will
adversely affect oil analysis results.
2.
Obtain two sample bottles (NSN 8125-01-082-9697) and two DD Form 2026s from the unit AOAP monitor.
3.
Start engine (WP 0021 00). If required (refer to Sampling Requirements paragraph), operate carrier to bring engine
and transmission up to normal operating temperatures.
4.
Stop carrier and set the brakes.
5.
Place range selector in SL position (steering lock) and keep engine running.
6.
Remove driver's power plant access panel (WP 0040 00).
