Drive Pinion Assemble

Drive Pinion Assemble

^ Tools Required
- J 42164 Pinion Gear Holder
- J 42170 Bearing and Race Installer
- J 42172 Bearing Race Installer/Spanner Wrench





1. Important: The spacer is specific for the bearing set and must be used in order to achieve the proper bearing preload. The pinion bearings, spacer and housing/cage must be replaced as a set.

Install the inner bearing cup into the pinion housing/cage using the J 42172 and a hydraulic press, if required.





2. Install the outer bearing cup into the pinion housing/cage using the J 42170 and a hydraulic press, if required.





3. Install the bearing onto the pinion shaft using the J 42170, J 42164, and a hydraulic press.





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





5. Press the bearing onto the pinion shaft using J 42170, J 42164, and a hydraulic press.





6. Notice: Refer to Fastener Notice in Service Precautions.

Install the nut onto the pinion shaft using a torque wrench, J 42172, and J 42164.
^ Tighten the nut to 500 Nm (370 ft. lbs.).
7. Using a punch, stake the areas of the nut into the notches in the end of the pinion shaft.
8. 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 Nm (12 - 25 inch lbs.).
