5-117.1
INSPECT BEARING
CAUTION
Replace swashplate assembly if any
of the conditions in step 4 are found.
NOTE
Do not attempt to clean or wipe
the grease from bearing prior to
performing the next step.
4.
Visually inspect grease for debris and bearing (9)
for damage. Use a flashlight or other suitable
light source. Inspect for orange/red pieces of
debris. The lower grease seal is elastomeric
orange/red in color; therefore this type of rubber
debris may be indicative of damage to the lower
seal. Inspect the bearing ball separator cages
(10) for damage, such as raised, overlapping,
or broken cage segments, or multiple adjacent
uncaged ball bearings.
WARNING
Do not use cloths or rags to clean
the bearing area as this may snag or
catch on the bearing cage.
5.
Using fingers, wipe away excess grease in cavity
and repeat instructions in step 4 above.
CAUTION
Replace grease seal if crack is found.
6.
Inspect grease seal (2 or 6) for nicks, scratches,
gouges, distortion, and cracks around bolt/stud
holes.
a.
Blend out minor nicks, scratches, and gouges
with abrasive paper (E14).
b.
Apply alodine (E65) with brush (E86) to
repaired area of grease seal (2 or 6). Wear
gloves (E184.1).
c.
Apply one coat of epoxy primer (E292.1) to
repaired area of grease seal (2 or 6). Allow
primer to dry for 30 minutes. Wear gloves
(E184.1).
