REPAIR RAMP WINCH (Continued).
4 INSPECT PRIMARY PLANET ASSEMBLY
a. Inspect and replace snap ring (54), garter spring
(51) and 'O' ring (56).
b. Check the planet hub (45). Inspect the seal
diameter for scores or roughness. Try
removing roughness with extra fine emery
cloth. If roughness can not be removed
completely in this way, replace the planet hub
(45).
c. Inspect the planet pin bores for scores and
bruises which may have been caused in
removing the planet pins (46). Remove the high
spots of any scores or bruises carefully with a
scraper, sufficiently to allow a planet pin (46) to
be pressed into each bore by hand.
d. Inspect the pins (44) for damage. If they are
bent or distorted, discard them.
e. Inspect the planet pins (46) for excessive
wear at the bearing and cam lock areas. If the
wear at the bearing and cam lock areas is
greater than 0.001" on the diameter when
compared with the unworn areas, the planet pins
(46) should be replaced.
f.
Inspect the bore of the planet gears (48) for
ridges in the center area of the bore and for
wear at the center and ends of the bore. If there
are definite ridges at the center of the bore or
wear at any part of the bore greater than 0.001"
in diameter, the gears will require replacement.
The original bore diameter was 1.7852".
