Removal & Installation




NOTE
The inertial weight section of the crankshaft balancer is assembled to the hub with a rubber type material. The correct installation procedures (with the proper tool) must be followed or movement of the inertial weight section of the hub will destroy the tuning of the crankshaft balancer.

  1. Remove the drive belt.
  2.  
  3. Remove the right front tire and wheel.
  4.  
  5. Remove the right engine splash shield.
  6.  
  7. Install the jack stands to the frame.
  8.  
  9. Loosen the left frame bolts and remove the right side frame bolts.
  10.  
  11. Using the jack stands, lower the right side of the frame to access the crankshaft balancer.
  12.  
  13. Remove the torque converter cover.
  14.  
  15. Install the J 43442 tool to the flywheel to prevent flywheel rotation.
  16.  
  17. Remove the crankshaft balancer bolt and the washer.
  18.  
  19. Using the J 41816 tool, remove the crankshaft balancer.
  20.  

To install:

  1. Apply sealant, GM P/N 12378521 (Canadian P/N 88901148) or equivalent to the keyway of the balancer.
    NOTE
    Do NOT use a power-assisted tool with the special tool in order to remove or install this component. You cannot properly control the alignment of this component using a power-assisted tool, and this can damage the component.

    NOTE
    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.
