4.
Mount the adaptor plate and puller (FIGURE6-4,
page 23), and pull the gear hub. Be sure to use
a shaft protector to prevent damage to the end of
the shaft. Remove the key from the shaft.

5.
Mount the adaptor plate and puller (FIGURE6-5),
and pull the pinion. Use a shaft protector.
Remove the key from the shaft.
6.
If a hydraulic puller is not available, the hub and
pinion may be pulled as shown in FIGURE6 - 6.
Do not use a torch to heat the pinion
to aid in removal. The pinion can be
damaged by concentrated heat.
3.
Place the unit in a horizontal position, on a solid
blocking, so the gear end bearing carrier hangs
free. Drain oil from both carriers. At the gear end
remove the cover, hub retainer plate, gear (slip fit
on hub) and pinion locknut. A spanner wrench
similar to that shown in FIGURE6-3, should be
made to prevent damaging the lock- nuts. This
wrench is especially useful at assembly in saving
time, and, more important, assures proper
tightening of the nuts.
7.
Remove all gear end bearing carrier to housing
screws. With four jack screws in tapped holes in
the carrier flange, FIGURE6-7, page 35, pull
the carrier. This also pulls bearings from the
rotor shaft. Tighten jack screws evenly to prevent
bind- ing carrier on dowel pins and bearings.
Support the carrier so it does not drop and
damage shaft extensions. When the carrier is
free, remove the bearing retainers, bearings, lip
type oil seal and shaft seals. If the bearings are
to be reused, handle with care.
