4-3 GENERAL INFORMATION.
a. Before beginning a task, find out how much repair, modification, or
r e p l a c e m e n t 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
d a m a g e d or broken parts.
b . All tags and forms attached to the equipment must be checked to learn the
reason for removal from service. Check all Modification Work Orders (MWO) and
Technical Bulletins (TB) for equipment changes and updates.
c . In some cases a part may be damaged by removal. If the part appears to be
good, and other parts behind it are not defective, leave it on and continue the
procedure. Here are a few simple rules:
(1) Do not take out dowel pins or studs unless loose, bent, broken or
otherwise damaged.
(2) Do not pull out bearings or bushings unless damaged. If you must get at
parts behind them, pull out bearings or bushings carefully.
(3) Replace all gaskets, seals, and packings.
