Ring Gear and Differential Housing Assemble

Ring Gear and Differential Housing Assemble

^ Tools Required
- J 42162 Side Gear Compressor
- J 42170 Bearing and Race Installer
- J 42173 Differential Holding Fixture





1. Important: Friction discs and separator plates develop specific wear patterns. During disc and plate installation, the components must be installed in the specific order in which they were removed.

Install the right clutch pack to the right case.
^ Install the separator plates (4).
^ Install the friction discs (3).
^ Install the friction disc - thick (2).
^ Install the Belleville washer (1).





2. Install the right output shaft and gear (3), side gears (1), and washers (2) to the right differential case.





3. Using the J 42162 and a hydraulic press, compress the Belleville washer and clutch pack in order to install the cross pin to the right differential case.





4. Using an M8 bolt for alignment, properly position the cross pin into the right differential case. The hole in the pin (2) must align with the hole in the case. During final assembly of the case halves, the pin retaining bolt (1) must be able to pass through the hole in the cross pin.
5. With the pin and case aligned, release the pressure from the press and remove the J 42162 and bolt.





6. Install the gear to the left output shaft.





7. Install the C-clip to the left output shaft.





8. Using the J 42170 and a hydraulic press, install the left side bearing to the differential.





9. Important: Friction discs and separator plates develop specific wear patterns. During disc and plate installation, the components must be installed in the specific order in which they were removed.

Install the left clutch pack to the left case.
^ Install the separator plates (1).
^ Install the friction discs (2).
^ Install the friction disc - thick (3).
^ Install the Belleville washer (4).





10. Install the left output shaft and gear to the left case.





11. Assemble the case halves.

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

Install the case bolts.
^ Tighten the bolts to 55 Nm (41 ft. lbs.).





13. Using the J 42170 and a hydraulic press, install the right side bearing to the differential.





14. Install the ring gear (1) to the differential. Use several bolts to properly align the ring gear to the case. A hammer and brass punch may be used to aid in seating the ring gear onto the differential case.
15. Install the NEW ring gear bolts (2).





16. Position the differential assembly onto the J 42173.
^ Tighten the ring gear bolts to 195 Nm (144 ft. lbs.).
