Repairing the Pinion
NOTE: Refer to Fig. 10 except where noted.
NOTE: A hydraulic press is required if you purchase
the pinion parts individually. Otherwise, use Repair Kit
No. 240162, which includes the shaft and bearings
pre–assembled and lubricated.
If using Repair Kit 240162, follow Steps 1 to 5, below.
1. Remove the small ring (19m**) from the hub (19j)
and the large ring (19k) from the bearing recess of
the pinion housing (19a).
2. Push on the front of the shaft (19g**) to force the
bearing and hub assembly out of the housing
(19a).
3. Install the new shaft assembly into the pinion
housing; push it to the shoulder of housing (19a).
4. Install the ring (19k) and then the ring (19m**).
5. Go to Reassembly, page 25, step 7., or continue
on page 20.

(19h) and press the shaft through the hub and
bearing. See Fig. 11.
5. Apply lubricant to the parts as shown in Fig. 10.
