UNIT PREVENTIVE MAINTENANCE CHECKS

AND SERVICES (PMCS) INTRODUCTION

GENERAL

To ensure that the M915 Family of Vehicles are ready for operation at all times, they must be lubricated and inspected on

a regular basis so that defects may be found before they result in serious damage, equipment failure or injury to person-

nel.

The KEY in this work package lists the types, amounts, and temperature ranges of the lubricants required for specified

intervals.

Lubrication Charts at the end of this work package show all lubrication points.

Table 1 in WP 0023 00 contains systematic instructions on lubrications, inspections, adjustments, and corrections to be

performed by Unit Maintenance to keep the tractor in good operating condition and ready for its primary mission.

Tables 2 and 3 at the end of WP 0023 00 list PMCS mandatory replacement parts, by interval.

For information on Corrosion Prevention and Control (CPC), refer to WP 0001 00.
