Harmonic Balancer - Crankshaft Pulley



Important: Make sure that the teeth of J 42386-A mesh with the teeth of the engine flywheel. The used crankshaft balancer bolt will be used only during the first pass of the balancer installation procedure. Install a NEW bolt and tighten as described in the second, third and forth passes of the balancer bolt tightening procedure. The crankshaft balancer installation and bolt tightening involves a four stage tightening process. The first pass ensures that the balancer is installed completely onto the crankshaft. The second, third, and forth passes tighten the new bolt to the proper torque.

Install the used crankshaft balancer bolt.

Tighten the USED bolt to 330 Nm (240 ft. lbs.)

Remove the used crankshaft balancer bolt.







Important: The nose of the crankshaft should be recessed 2.4 - 4.48 mm (0.094-0.176 inch) into the balancer bore.
