GENERAL MAINTENANCE INSTRUCTIONS
GENERAL
NOTE
Refer to WP 0120 00 for Electrical General Maintenance Instructions.
1.
These general maintenance instructions contain general shop practices and specific methods you must be familiar with
to properly maintain the M878A2 Yard Tractor. You should read and understand these practices and methods before per-
forming any Unit Maintenance procedures.
2.
Before beginning a task, find out how much repair, modification or replacement is needed to fix the equipment. Some-
times the reason for equipment failure can be seen right away and complete teardown is not necessary. Disassemble
equipment only as far as necessary to repair or replace damaged parts.
3.
In some cases, a part may be damaged during removal. If the part appears to be good, and other parts behind it are not
defective, leave it in place and continue with the procedure. Here are a few simple rules:
a.
Do not remove dowel pins or studs unless loose, bent, broken or otherwise damaged.
b.
Do not remove bearings or bushings unless damaged. If you need to remove them to access parts behind, carefully
pull out bearings and bushings.
c.
Replace all gaskets, lockwashers, locknuts, seals, cotter pins, and o-rings.
4.
All tags and forms attached to the equipment must be checked to learn the reason for removal of equipment from ser-
vice. Modification Work Orders (MWOs) and Technical Bulletins (TBs) must also be checked for equipment changes
and updates.
WORK SAFETY
1.
Before beginning a procedure, think about the safety risks and hazards to yourself and to others. Wear protective gear
such as safety goggles or lenses, safety shoes, rubber apron or gloves.
