(1)
Check all bushings and bushing-type bearings for secure fit, evidence of overheating, wear, burrs,
nicks, and out-of-round condition.
(2)
Check for dirt in lubrication holes or grooves. Holes and grooves must be clean and free from damage.
g. Oil Seals.
Oil seals are mandatory replacement items.
h. Core Hole Expansion Plugs.
Inspect for leakage. Replace plugs when leakage is present.
i. Machine Tooled Parts.
Inspect for cracks, breaks, elongated holes, wear, and chips.
j. Machined Surfaces.
Inspect for cracks, evidence of wear, galled or pitted surface, burrs, nicks, and
scratches.
k. Mated Surfaces.
Inspect for remains of old gasket, seal, evidence of leakage, pitting, and secure fit.
1. Rusted Surfaces.
Inspect for pitting, holes, and severe damage.
m. Oil Bathed Internal Parts.
Inspect for cracks, nicks, burrs, evidence of overheating, and wear.
n. Air-Actuated Internal Parts.

2-10. REPAIRS
a. General Instructions.
Repair of most parts and components is limited to general procedures outlined
in applicable maintenance instructions and the following procedures, “b” through “h.”
CAUTION
Repaired items must be thoroughly cleaned to remove metal chips
and abrasives. Metal chips and abrasives can enter working parts
of vehicle and cause damage to equipment.
b. Castings.
(1)
All cracked castings will be replaced.
(2)
Only minor repairs to machined surfaces, flanges, and gasket mating surfaces are permitted. Remove
minor nicks, burrs, and/or scratches with:
(a)
Fine mill file.
(b)
Crocus cloth dipped in cleaning solvent.
(c)
Lapping across a surface plate.
(3)
Remachining of machined surfaces to repair damage, warpage, or uneven surfaces is not permitted.
Replace castings.
(4)
Repair damaged threaded pipe plug and/or screw threads with a tap. Repair oversize holes with
threaded inserts.
c. Bearings.
Refer b TM 9-214.
d. Studs.
Replace all bent and stretched studs. Repair minor thread damage with a thread die. Replace
studs having stripped or damaged threads as outlined below:
(1)
Remove using a stud remover. Back studs out slowly to avoid heat buildup and seizure which can
cause stud to break off.
CAUTION
Refer to TM 9-237, Welding Instructions, to avoid damage to
castings if welding method is used.
(2)
If studs break off too short to use a stud remover, use a stud extractor to remove, or use “welding
method.”
