1. INTERVALS

This LO has been revised with DA program to extend intervals to conserve lubricants. This

instruction applies only to vehicles in normal operation. Lubricate more frequently to

compensate for abnormal or extreme conditions, such as high or low 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 (4,800

km) on vehicles not accummulating 3,000 miles (4,800 km) in a 6-month period, will belubricated at time of Semiannual (“S”) Preventive Maintenance Service. Points requiring

lubrication at 6,000 miles (9,600 km) in a 6-month period, will be lubricated at least once a

year. Points requiring lubrication at 12,000 miles (19,300 km) will be lubricated annually.

When practicable, lubrication services will be made to coincide with the vehicle “S” Preventive

Maintenance Service. For this purpose, a 10 percent tolerance (variation) in specifiedlubrication point mileage is permissible.

2 . CRANKCASE BREATHER

Check and clean crankcase breather and lines every 6,000 miles (9,600 km) under normaloperating conditions.

3 . FUEL FILTERS

Drain primary fuel filter. If fuel filter contains dirt or water, drain secondary and final filters. ifdirt or water is found in final filter, notify organizational maintenance. Replace primary and

secondary filter elements and gaskets every 3,000 miles (4,800 km), 3 months, or 300 engine

hours, whichever occurs first, or at the discretion of the Maintenance Officer, as local conditionswarrant. Change final fuel filter during engine overhaul/rebuild or during troubleshooting.Do not drain filters completely.

4 . OIL FILTER

Oil filters will be changed only when directed by the oil analysis laboratory. Remove filter drainplug and elements; clean inside of case, and reinstall drain plug, new elements, and gaskets.

5 . CRANKCASE

a. Sample oil every 60 days or 1,000 miles (1 ,600 km). Army Reserve Units will sample

every 120 days or 1,000 miles (1 ,600 km). Oil will be changed only when directed by oil analysislaboratory.

NOTE

Submit oil samples as soon as they have been taken.

AOAP does not do away with seasonal oil changes. Make

oil changes as seasonal temperature requires.
