    • J 44538 TORX® 30+

    Object Number: 48237  Size: SH

    Important: Do not use any type of adhesive or sealer when assembling the gaskets. You may use J 36850 or equivalent as an aid.

  1. Install the case cover upper gasket (430) and the case cover lower gasket (429) on the case.

  2. Object Number: 1818448  Size: SH

    Important: Be careful to not move the gaskets.

  3. Use J 36850 or equivalent in order to retain the fourth clutch shaft thrust washer (432) and the drive sprocket/case cover thrust washer (514) to the case cover (400).
  4. Important: Rotate the internal mode switch (IMS) (802) all the way to the left as seen in the illustration. The tab on the IMS (802) has to be under the case cover or the manual shift detent assembly will not install properly.

  6. Object Number: 48203  Size: SH

    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.

    Important: Do not use an impact wrench.

  7. Finger start all transaxle case cover bolts (433-436) into the locations noted.
