GENERAL MAINTENANCE INSTRUCTIONS - CONTINUED
Refer to torque limits (WP 0335 00) for appropriate torque specifications of fasteners. Unless directed otherwise, always
tighten fasteners when installing them.
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.
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.
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:
Do not remove dowel pins or studs unless loose, bent, broken or otherwise damaged.
Do not pull out bearings or bushings unless damaged. If you must access parts behind them, pull out bearings or
Replace all gaskets, seals, O-rings, cotter pins, spring pins, self-locking nuts and lockwashers.
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic
material. However, It may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition.
Improper cleaning methods and use of unauthorized solvent cleaning compound may injure personnel
and damage equipment. Refer to TM 9-247 for correct information.
Fire extinguishers should be placed nearby when using solvent cleaning compound.
Cloths or rags saturated with solvent cleaning compound must be disposed of IAW authorized facilities'
Eye shields must be worn when cleaning with a wire brush. Flying rust and metal particles may cause
injury to personnel.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may result in
serious injury or death. Make sure air stream is directed away from user and other personnel in the area.
To prevent injury, user must wear protective goggles or face shield.
Cleaning instructions will be the same for the majority of parts and components.
The importance of cleaning must be thoroughly understood by maintenance personnel. Great care and effort are
required in cleaning. Dirt and foreign material are a constant threat to satisfactory maintenance. The following
should apply to all cleaning, inspection, repair and assembly operations.
