INSPECT FINAL PLANET ASSEMBLY
a. Inspect the planet pin bores In the planet hub
(59) for scores or bruises which may have been
caused in removing the planet pins. Remove
the high spots of any scores or bruises carefully
with a scraper, sufficiently to allow a planet pin
to be pressed into each bore by hand.
b. Inspect the planet pin (58) for excessive
wear at the bearing area. If wear exceeds
0.001" on the diameter, the pins should be
replaced.
c. Check the planet gears (60) for wear and
damage on the gear teeth. If wear is excessive,
replace the planet gears (60).
d. Inspect the ball bearings (61) for wear and
pitting at the balls and ball grooves. Replace
bearings if worn or pitted.
ASSEMBLY
1. ASSEMBLE FINAL PLANET ASSEMBLY.
a. Install the snap rings (62) in the bore of the
planet gear (60). Press the ball bearings (61)
into the final planet gear (60) so that the ends of
the bearings shoulder against the snap rings
(62).
b. Place the final planet gear (60) into the final
planet hub (59) so that the bore of the bearing
lines up with a planet pin hole.
c. Install a final planet pin (58) in the final planet
hub (59) so that it passes through the ball
bearings (61) in the planet gear and the drilled
hole in the final planet pin lines up with the hole
in the rim of the final planet hub.
