Tools Required

J 38122-A Harmonic Balancer Holder

1. Lubricate the front oil seal and sealing surface of the crankshaft balancer. Use Chassis Grease GM P/N United States 1051344, GM P/N Canada 993037 or the equivalent.
2. Install the balancer onto the crankshaft indexing keyway. Tap the balancer into place using a rubber or sand filled mallet.

Notice: Do not use the J 36660 Torque Angle Meter to rotate the retaining bolt an additional 90 degrees. The torque capacity of the tool will be exceeded and damage to the tool will result.

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: Use the J 38122-A to prevent the crankshaft from rotating.

3. Install the retaining bolt and washer.

Tighten

•	This mark will represent the zero point or 0 degrees.

•	Tighten the bolt by rotating the socket clockwise 90 degrees.

•	At 90 degrees the socket indexes with the next mark on the tool.
