On-Vehicle Service

REMOVE OR DISCONNECT
- Tools Required:
- J 8614-01 Companion Flange Holder






1. Bolts and retainers.

Important: It is essential that the positions of all driveling components relative to the propeller shaft and axles be observed and accurately reference marked prior to disassembly. These components include the propeller shafts, drive axles, pinion flanges, output shafts, etc. All components must be reassembled in the exact relationship to each other as they were when removed. Specifications and torque values, as well as any measurements made prior to disassembly, must be followed.

- Accurately mark the installed position of the propeller shaft and pinion flange so they can be reassembled in the same position.
2. Propeller shaft from the pinion flange.
A. Use a piece of tape to hold the bearing caps.
B. Secure the propeller shaft up and out of the way so as not to put unnecessary stress on the universal joints.
C. Make an accurate alignment mark on the pinion stem, pinion flange, and pinion flange nut. Also record the number of exposed threads on the pinion stem for reference.





D. Measure, using an inch-pound torque wrench, the amount of torque required to turn the pinion. Record this measurement for reassemble. This will give combined pinion bearing, seal, carrier bearing, axle bearing, and seal preload.
3. Pinion flange nut and washer.
- Use J 8614-01 to hold the pinion flange.
4. Pinion flange.
- Have a suitable container in place to catch lubricant.
5. Oil seal using a seal removal tool.
- Do not damage the carrier.

Inspect
1. Seal surface of the pinion flange for tool marks, nicks, or damage such as a groove worn by the seal. Replace the flange if necessary.
2. Carrier bore for burrs that might cause leaks around the outside of the seal.

INSTALL OR CONNECT
- Tools Required:
- J 8614-01 Companion Flange Holder
- J 23911 Pinion Oil Seal Installer






1. New seal using J 23911.
2. Seal lubricant to the outside of the pinion flange and the sealing lip of the new seal.
3. Pinion flange.

Important: Do not attempt to hammer the pinion flange onto the pinion stem.

4. Washer and nut.
- Tighten:
A. The nut on the pinion stem as close to the original marks as possible without going past the mark. Use the reference mark and the thread count as reference.
B. The nut a little at a time and turn the pinion flange several times after each tightening to set the rollers.

Measure
- Using an inch-pound torque wrench, the torque required to rotate the pinion. Compare this with the required rotating torque recorded earlier. Continue tightening and measuring a little at a time until the same preload is achieved.

Important:
- If the original preload torque value was less than 3 inch lbs. then reset the torque specification to 3-5 inch lbs.
- Align the propeller shaft with the alignment marks made previously.
- Use J 8614-01 to hold the pinion flange.

5. Propeller shaft to the pinion flange.
6. Bolts and retainers.
- Tighten bolts to 45 Nm (33 ft. lbs.).
