CAUTION
Do not remove bushings and bushing-type bearings unless
replacement is necessary and authorized. Removal usually
damages these parts.
If necessary to cut bushing, use care not to damage housing
bore.
b. Remove bushings and bushing-type bearings using puller or press when possible. Bushings in blind holes
may require removal by sawing or by using narrow cape chisel.
c.
Inspect thrust washers for wear, distortion, scores, and burrs. Minor defects may be corrected with crocus
cloth or soft honing stone. Parts that are worn, scored, or deformed must be replaced.
2-32. OIL SEALS, PREFORMED PACKINGS, AND GASKETS.
a. Inspect hook-type metallic seals rings for wear, distortion, cracks, and broken hooks. Ensure that edges of
hook rings are square.
b. Inspect composition-type seals, rings, and packings for wear, brittleness, cracks, cuts, deformation, and
deterioration. Replace defective seals.
CAUTION
Removing seal will usually damage it. If removal is necessary,
inspect seal thoroughly before using.
c.
Inspect lip seals for cracks, wear, cuts, and brittleness. Inspect springs and seal shells for deformation and
cracks. Replace defective seals.
d. All Preformed packings and gaskets should be replaced, if removed, and not reused.
2-33. SPLINED PARTS.
a. Inspect splined parts for burrs, wear, and twisted, cracked, or broken splines.
b. Remove burrs using soft honing stone. Replace parts that are excessively worn or have twisted, cracked, or
broken splines.
2-34. THREADED PARTS.
a. Inspect all threaded parts for burrs and stripped or damaged threads.
NOTE
If possible, chase threads with used tap or die. New tap may cut
oversize, while new die may cut undersize.
b. Replace all parts that have stripped threads. Replace parts that cannot be repaired by chasing threads with
used tap or die. Replace parts that cannot be repaired by installing helical coil inserts.
