1.
Refer to torque limits (WP 0335 00) for appropriate torque specifications of fasteners. Unless directed otherwise, always
tighten fasteners when installing them.
2.
Before beginning a task, find out how much repair, modification or replacement is needed to fix the equipment as
described in this manual. Sometimes the reason for equipment failure can be seen right away and complete teardown is
not necessary. Disassemble the equipment only as far as necessary to repair or replace damaged or broken parts.
3.
All tags and forms attached to the equipment must be checked to learn the reason for removal from service. Check all
Modification Work Orders (MWOs) and Technical Bulletins (TBs) for equipment changes and updates.
4.
In some cases, a part may be damaged by removal. If the part appears to be good, and other parts behind it are not defec-
tive, leave it on and continue 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 pull out bearings or bushings unless damaged. If you must access parts behind them, pull out bearings or
bushings carefully.
c.
Replace all gaskets, seals, O-rings, cotter pins, spring pins, self-locking nuts and lockwashers.
