GENERAL CLEANING.
Cleaning is very important. All parts must be cleaned well and kept clean during
maintenance. Dirt or foreign matter can cause malfunctions and equipment failure. General cleaning procedures are
detailed in the following steps. Special cleaning procedures are covered in the task relating to the specific part. Clean
after repair and before assembly.
a.
CLEAN EVERY PART.
Clean every part well after disassembly and before assembly or installation. Clean parts
such as housings, covers, and dipsticks before disassembly. Avoid getting dirt and foreign matter in a system.
Inspect and cap all air and fluid openings, lines, and hoses.
b.
HANDLE WITH CARE.
Use care when handling parts during cleaning and maintenance. Nicks, scratches, dents,
and burrs can prevent proper assembly or cause malfunctions after assembly. Keep hands free of grease. Grease
collects dirt. Cover or wrap parts to protect from dirt.
c.
AVOID ABRASIVES.
Except where specially called for in a task, don’t use abrasives, files, wire brushes, or sharp
tools. On some surfaces, finish is important to the operation of close fitting parts.
d.
REMOVAL AGENTS.
Remove gum or old grease deposits by soaking parts in solvent, cleaning compound. Scrub
with a brush. Use crocus cloth to remove minor surface defects.
WARNING
Air pressure in excess of 30 psi (207 kPa) can injure personnel. Do not direct pressurized air
at yourself or others. Always wear goggles.
e.
STEAM CLEANING.
If steam cleaning is used, dry clean parts at once with compressed air. Apply a thin film
of clean oil to surfaces that are not painted to prevent rusting. Never use lye or caustic mixtures that will corrode
or etch metal surfaces.
f.
LUBRICATION OF NEW BEARINGS.
See TM 9-214 for cleaning and lubrication procedures. Bearings that
have been in service should also be lubricated.
WARNING
Air pressure in excess of 30 psi (207 kPa) can injure personnel. Do not direct pressurized air
at yourself or others. Always wear goggles.
g.
CASTINGS.
1)
Clean inner and outer surfaces of casting with solvent, cleaning compound. Dry casting with compressed air.
2)
Remove sludge and gum deposits with a brush.
3)
Blow out all tapped holes and armor mounting inserts with compressed air.
h.
BALL BEARINGS.
Bearings require special cleaning techniques. See TM 9-214 for cleaning and maintenance
procedures for ball bearings.
