Tools Required

1. Install the bearing onto the pinion shaft using the J 42170  (1), J 42164  (2), and a hydraulic press.



2. Assemble the pinion shaft (5), spacer (3), and bearing (2) into the housing/cage (4).



3. Press the bearing onto the pinion shaft using J 42170  (1), J 42164  (2), and a hydraulic press.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Install the nut onto the pinion shaft using a torque wrench, J 42172  (1), and J 42164  (2).

Tighten
Tighten the nut to 500 N·m (370 lb ft).

5. Using a punch, stake the areas of the nut into the notches in the end of the pinion shaft.
6. Measure the rotating torque of the pinion shaft using the J 42164 . A properly assembled pinion shaft and bearings should have a rotating torque of 1.4-2.8 N·m (12-25 lb in).
