PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
To ensure the 966H Wheel Loader is ready for operation at all times, it must be inspected on a regular basis so defects
may be found and corrected before they result in injury, damage, or equipment failure.
Table 1 in WP 0020 00 contains systematic instructions on inspections, lubrications, services, tests, and corrections to be
performed by Unit Maintenance to keep your equipment in good operating condition and ready for its primary mission.
Table 2 in WP 0020 00 lists mandatory replacement parts, by interval, for the loader.
The KEY, located with General Lubrication Procedures immediately after Table 2, lists the types, amounts, and temper-
ature ranges of the lubricants required for specified intervals.
The Lubrication Chart following the KEY shows all Unit Maintenance level lubrication points for the 966H. Localized
views follow the Lubrication Chart.
For information on Corrosion Prevention and Control (CPC), refer to WP 0001 00 in Volume 1.
