UNIT MAINTENANCE PREVENTIVE MAINTENANCE CHECKS

AND SERVICES (PMCS) INTRODUCTION

GENERAL

To ensure that the D7F Tractor is ready for operation at all times, it 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 personnel.

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

intervals.

The Lubrication Chart at the end of this work package shows all Unit Maintenance level lubrication points for the D7F

Tractor.

Table 1 in WP 0009 00 contains systematic instructions on lubrications, inspections, adjustments and corrections to be

performed by Unit Maintenance to keep the D7F Tractor in good operating condition and ready for its primary mission.

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

NOTE

The WARNINGs and CAUTIONs appearing in your PMCS table should always be observed. WARNINGs

and CAUTIONs appear before applicable procedures. These WARNINGs and CAUTIONs must be

observed to prevent serious injury to yourself and others or to prevent your equipment from being dam-

aged.

Procedure Column. This column gives the procedure you must perform to check or service the item listed in the Item

to Check/Service column, to know if the equipment is ready or available for its intended mission or for operation. You

must perform the procedure at the time stated in the interval column.

GENERAL LUBRICATION PROCEDURES

NOTE

Lubrication instructions contained in this PMCS are MANDATORY.

Dashed leader lines used in illustrations of lubrication points indicate that lubrication is

required on both sides of the equipment.

Recommended intervals are based on normal conditions of operation, temperature, and humidity. When operating under

extreme conditions, such as high or low temperatures or exposure to sand or dust, lubricants should always be changed

more frequently. Lubricants that have become contaminated will be changed regardless of interval. When in doubt,

notify your supervisor.
