Tools Required

J 35271 Flywheel Holder

1. Align the flywheel-to-engine marks and install the flywheel (3) to the crankshaft.

Notice: Apply the proper amount of the sealant to the fastener when assembling this component. Excessive use of the sealant can prohibit the component from being assembled properly or allow the fastener to loosen. A component or fastener that is not assembled properly can loosen or fall off leading to extensive engine damage.

2. Apply GM P/N 12345493, Canadian P/N 10953488 or the equivalent, to the flywheel retaining bolt threads.




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.

3. Install the flywheel retaining bolts to the crankshaft. Use the J 35271 to lock the flywheel.

Tighten
