    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.

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

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

    3. Object Number: 58612 Size: SH
  3. Using the J 42162 and a hydraulic press, compress the bellville washer and clutch pack in order to install the cross pin to the right differential case.

    4. Object Number: 354426 Size: SH
  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.

    11. Object Number: 58600 Size: SH
  11. Assemble the case halves.

    12. 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.

  12. Install the case bolts.

    13. Tighten
    Tighten the bolts to 55 N·m (41 lb ft).
