PINION REPLACEMENT PROCEDURE
(Reaction Camer Shown)
1. Support camer assembly on its front face.
2. Using a 1/2" diameter drill, remove stake marks
from end of the pinion pin or pins to be replaced. This
will reduce the probability of cracking the carrier when
pinion pins are pressed out.
CAUTION: Do not allow drill to remove any stock from
the carrier as this will weaken the part and future failure
would be probable.
3. Using a tapered punch, drive or press pinion pins
out of camer (Fig. 7E-119).
4. Remove pinions, thrust washers and roller needle
bearings.
5. Inspect pinion pocket thrust faces for burrs and
remove if present.
