Tools Required
J 38122-A Crankshaft Balancer Holder
- Lubricate the front oil seal and sealing surface of the crankshaft balancer. Use Chassis Grease GM P/N 1051344 or equivalent.
- Install the balancer onto the crankshaft indexing keyway. Tap the balancer into place using a rubber or sand filled mallet.
- Install the retaining bolt and washer.
- Put a mark on the socket next to one of the four marks on the J 38122-A . 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.
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.
Tighten
Tighten the bolt to 175 N·m (129 lb ft).
Use the J 38122-A
to prevent
the crankshaft from rotating.
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.
