Removal Procedure

Tools Required

    • J 36660-A Torque Angle Meter
    • J 37096 Flywheel Holding Tool

    Object Number: 74285  Size: SH
  1. Remove the transaxle. Refer to Transaxle Replacement in Automatic Transaxle On-Vehicle Service.
  2. Remove the eight bolts attaching the flywheel to the crankshaft flange and discard them. Use the J 37096 in order to prevent crankshaft rotation.
  3. Remove the flywheel.

Installation Procedure


    Object Number: 74285  Size: SH
  1. Install the flywheel.
  2. Install the new flywheel bolts. Use the J 37096 in order to prevent the crankshaft from rotating.
  3. Tighten
    Tighten the flywheel bolts to 15 N·m (11 lb ft). Use the J 36660-A in order to rotate the bolts an additional 50°.

    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.

  4. Use the following procedure to measure flywheel runout:
  5. 3.1. Install a dial indicator on the engine block and check the flywheel runout at three attaching bosses.

            Important: The crankshaft end play must be held in one direction during this check. Runout should not exceed 0.38 mm (0.015 in).

    3.2. If the runout exceeds 0.38 mm (0.015 in), attempt to correct by tapping the high side with a mallet.
    3.3. If the condition cannot be corrected, replace the flywheel.
  6. Install the transaxle. Refer to Transaxle Replacement in Automatic Transaxle On-Vehicle Service.
