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.

If purchasing parts separately, use these instructions. Disassemble as far as needed for the parts being replaced.
