Cleaning
a.
General.
The following procedures shall be
applied in all maintenance work:
(1
) Clean all parts before inspection, after repair,
and before assembly.
(2
) After cleaning, cover all parts or wrap them in a
suitable covering as protection against dust and dirt.
b.
Castings
(1
) Clean the inner and outer surfaces of castings
and all areas subject to oil and grease with a dry-
cleaning solvent or mineral spirits paint thinner.
(2
) Remove sludge and gum deposits from castings
using stiff brush.
WARNING
Particles
blown by compressed air
arehazardous.
Make certain the air
stream is directed away from the user
and any other persons in the area.
(3
) Blow out all tapped holes with compressed air
and dry castings, after cleaning with compressed air.
c.
Oil passages.
All oil passages must be clean
and free of obstructions.
(1
) Clean passages with wire or probes to break up
any sludge or gum deposits.
(2
) Wash passages by flushing with dry-cleaning
solvent or mineral spirits paint thinner.
(3
) Dry passages by blowing them out with dry,
compressed air.
d.
Oil Seals, Electric Cables, and Flexible Hoses.
Clean seals, cables, and flexible hoses with soap and
water.
CAUTION
Do not allow dry-cleaning solvent or
mineral spirits paint thinner to be in
contact with seals, cables, and flexible
hoses. These cleaners cause leather,
rubber, and synthetic materials to dry
out, rot, and lose pliability, making them
unserviceable.
e.
Ball Bearings.
Refer to TM 9-214 for information
on care and maintenance of bearings.
2-6.
Inspection
a.
Castings.
(1
) Inspect all ferrous (cast iron, steel, etc.) castings
for cracks with magna-flux equipment. Inspect all non-
ferrous
(aluminum)
castings
for cracks using a
magnifying glass and a strong light. Carefully check
areas adjacent to studs, pipe plugs and threaded inserts,
also check sharp corners and fillets.
(2
) Inspect machined surfaces of castings for nicks,
burrs, or raised metal, and mark damaged areas for
repair.
(3
) Check all mating flanges on housings and
supports with straight edge or surface plate for warpage.
Inspect mating flanges for discoloration which may
indicate persistent oil leakage.
(4
) Inspect all pipe plug and cap screw tapped
openings for damaged or stripped threads.
