These general maintenance instructions contain general shop practices and specific methods you must be
familiar with to properly maintain the equipment. You should read and understand these practices and methods
before performing any maintenance procedures.
Before beginning a task, find out how much repair, modification, or replacement is needed to fix the equipment.
Sometimes 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.
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:
Do not remove dowel pins or studs unless loose, bent, broken, or otherwise damaged.
Do not remove bearings or bushings unless damaged. If you need to remove them to access parts
behind, carefully pull out bearings and bushings.
Replace all gaskets, lockwashers, locknuts, seals, cotter pins, and O-rings.
The following "Initial Setup" information applies to all maintenance procedures:
Resources are not listed unless they apply to the procedure.
"Personnel Required" is listed only if more than one mechanic is required to complete the procedure.
