bearings or excessive tilt.
1. Support carrier assembly on its front face.
2. Using a 1/2" diameter drill, eliminate the stake
marks from end of the pinion pin or pins to be re-
placed. 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 fdure would be probable.
3. Using a tapered punch, drive or press pinion pins out
of carrier (Fig. 7E-147).
