2 - 8 . CLEANING (Contd)
WARNING
Do not use compressed air or a dry brush for cleaning when
working in areas of vehicle where asbestos brake lining dust may
accumulate. Remove asbestos dust and other residue from these
areas using a soft bristle brush or cloth soaked with water.
Breathing asbestos dust may cause injury to personnel.
k. Brake Lining Surfaces. Clean all components where brake lining (asbestos) dust could accumulate
with a wet nonspray process. Bulk oil-based residues can be removed by scraping followed by wiping with
cleaning solvent soaked rag.
2-9. INSPECTION
a. General Instructions. Procedures for inspections will be the same for many parts and components
which make up the vehicle subassemblies. General procedures are detailed in "b" through "q." Dimensional
standards for parts have been fixed at extremely close tolerances, so use specification tables. Use specified
inspection equipment for inspection where cracks and other damage cannot be spotted visually. Exercise
extreme care in all phases of inspection.
b. Castings.
(1) Inspect all ferrous and nonferrous castings for cracks using a magnifying glass and strong light.
(2) Refer to MIL-I-6866, Inspection, Liquid Penetrant Methods, and MIL-I-6868, Inspection Process,
Magnetic Particles.
(3) Particularly check areas around studs, pipe plugs, threaded inserts, and sharp corners. Replace
all cracked castings.
(4) Inspect machined surfaces for nicks, burrs, or raised metal. Mark damaged areas for repair
or replacement.
(5) Inspect all pipe plugs, pipe plug openings, screws, and screw openings for damaged or
stripped threads.
(6) Check all gasket mating surfaces, flanges on housings, and supports for warpage with a straightedge
or surface plate. Inspect mating flanges for discolorations which may indicate persistant oil leakage.
(7) Check all castings for conformance to applicable repair standards.
c. Bearings. Refer to TM 9-214 for inspection of bearings. Check all bearings for conformance to applicable
repair standards.
d. Studs, Bolts, and Screws. Replace if bent, loose, stretched, or threads are damaged.
e. Gears.
NOTE
When gear teeth wear limits are not established, good judgement
is required to determine if gear replacement is necessary.
(1) Inspect all gears for cracks using a magnifying glass and strong light. No cracks are allowed.
(2) Inspect gear teeth for wear, sharp fins, burrs, and galled or pitted surfaces.
(3) Check keyway slots for wear and/or damage.
(4) Check oil holes for obstructions.
