IMPORTANT:

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 fourth passes tighten the
NEW bolt to the proper torque.

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
fourth passes of the balancer bolt tightening procedure.
