J 36660-A Torque Angle Meter

1. Install the flywheel to the crankshaft. Align the flywheel-to-engine marks.

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 (1).





Notice: Refer to Fastener Notice (Fastener Notice).

3. For vehicles equipped with an automatic transmission, install the flywheel retaining bolts (1-8) to the crankshaft.

Tighten the 8 flywheel retaining bolts in the sequence shown for automatic transmission to 83 N.m (61 lb ft).





4. For vehicles equipped with a manual transmission, install the flywheel retaining bolts to the crankshaft and torque the bolts in 2 steps.

Tighten the eight flywheel retaining bolts in the sequence shown for manual transmission to 49 N.m (36 lb ft).





5. Perform the final torque on the manual transmission flywheel retaining bolts.

After the proper torque of 49 N.m (36 lb ft) has been reached, use a J 36660-A and tighten the flywheel bolts an additional 90 degrees.
