Installation Procedure

Tools Required

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

    Object Number: 41361  Size: SH
  1. Lubricate the seal surface with engine oil.
  2. Install the crankshaft balancer.
  3. Notice: This bolt is designed to permanently stretch when tightened, and therefore MUST be replaced anytime it is removed. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.

    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. Install the balancer bolt. Hold the flywheel with the J 37096 .
  5. Tighten
    Tighten the bolt to 150 N·m (111 lb ft). Use the J 36660-A in order to rotate the bolt an additional 76 degrees.
