TM 9-2350-261-10 PREVENTIVE MAINTENANCE CHECKS AND SERVICES — Continued 0075 00 Frequency of AOAP Sample: Every 60 days obtain samples of engine and transmission oil and send to the nearest AOAP Laboratory (TB 43-0211). Take samples as near the prescribed interval as possible. If sampling at the prescribed interval is not possible, a 10 percent variance before or after the scheduled interval date or miles is permissible. The need for on-condition oil changes will be determined by the AOAP Laboratory. 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 level, 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 0026 00). If required (refer to Sampling Requirements paragraph above), operate carrier (WP 0028 00) to bring engine and transmission up to normal operating temperatures. 4. Stop carrier and set the brakes. 5. Shift range selector to N (neutral) and keep engine running. 6. Remove driver’s power plant access panel (WP 0048 00). 0075 00-5
