FIGURE 6-5
The adaptor plates shown are designed for a jaw type hydraulic puller, FIGURE 6-4 and
FIGURE 6-5. Other type pullers are available, and if used, suitable adaptor plates should be
provided.
Pulling directly on pinion teeth will damage teeth making timing difficult and will cause gear
wear. Pulling directly on the gear hub flange will distort the flange causing gear run-out..
3. Place the unit in a horizontal position, on a solid blocking, so the gear end bearing carrier (4)
hangs free. Drain oil from both carriers. At the gear end remove the cover (15), hub retainer
plate (13), gear (8) which has slip fit on hub (9) and pinion locknut and lockwasher (33, 35). A
spanner wrench similar to that shown in FIGURE 6-3, should be made to prevent damaging the
locknut. This wrench is especially useful at assembly in saving time, and more important,
assures proper tightening of the nuts.
4. Mount the adaptor plate (FIGURE 6-2) and puller (FIGURE 6-4), and pull the pinion (7). Be sure
to use a shaft protector to prevent damage to the end of the shaft. Remove the key (41) from the
shaft.
5. Mount the adaptor plate (FIGURE 6-1), and puller (FIGURE 6-5), and pull the gear hub (9). Use
a shaft protector. Remove the key (41) from the shaft.
6. If a hydraulic or mechanical puller is not available, the hub and pinion may be pulled as shown in
FIGURE 6-6.
