Pinion Oil Seal and Associated Parts

Removal
1. Remove the rear propeller shaft.
2. Drain the rear axle oil.





3. Check and record preload with an inch pound torque wrench. This will give combined pinion bearing, seal, carrier bearing, axle bearing and seal preload.





4. Remove flange nut and washer by using pinion flange holder J-8614-01 after raising up its staked parts completely.





5. Remove flange by using SST J-8614-1-3.
^ Have a suitable container in place to catch lubricant.

6. Remove oil seal.
7. Remove pinion oil seal slinger.





8. Remove outer bearing by using remover J-39602
9. Remove collapsible spacer.

Inspection and Repair
Make necessary correction or parts replacement if wear, damage, corrosion or any other abnormal condition are found through inspection.
Check the following parts.
1. Seal surface of the flange.
2. Cage bore for burns.

Installation
1. Install collapsible spacer, discard the used collapsible spacer and install a new one.
2. Install outer bearing.

Note: Do not drive in, but just temporarily set in the outer bearing by hand, which should be indirectly pressed in finally by tightening the flange nut





3. By using the seal installer J-37263, install a new oil seal (1) that has grease on seal lip.
4. Install flange.





5. The pinion washer and a new nut while holding the pinion flange with J-8614-01.
^ Tighten the nut until the pinion end play is just taken up. Rotate the pinion while tightening the nut to seat the bearings. Once there is not end play in the pinion, the preload torque should be checked.
^ Remove J-8614-01. Using an inch-pound torque wrench, check to make sure the pinion preload is equal to or slightly over the reading recorded during removal.

6. Install propeller shaft to the range.
7. Install bolt and nut. Tighten the bolt and nut to the specified torque.
