Tools Required

J 24420-C Crankshaft Pulley/Hub Puller/Gear Puller

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Notice: The inertial weight section of the balancer is assembled to the hub with a rubber type material. The correct removal procedure must be followed or movement of the inertial weight section of the hub will destroy the tuning of the balancer.

Tools Required

J 29113 Crankshaft Balancer Installer

Notice: The inertial weight section of the balancer is assembled to the hub with a rubber type material. The correct removal procedure must be followed or movement of the inertial weight section of the hub will destroy the tuning of the balancer.

1. Coat the front cover seal contact area with engine oil.
2. Apply sealant to the crankshaft key. Apply sealant to the crankshaft keyway. Use GM RTV sealant P/N 1052917 or the equivalent.



3. Place the balancer into position over the key in the crankshaft.
4. Install the J 29113 onto the crankshaft.
5. Pull the balancer into position.
6. Remove the J 29113 from the balancer.

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.

7. Install the balancer retaining bolt. Have an assistant keep the flywheel from turning.
