3.20" bolt pattern

Includes Spacer, shims and bolts

Note: This spacer kit is for use with the factory balancer.

Remove the three bolts on the front
of the balancer. With a wire brush,
thoroughly clean the 3 counter bores of
the balancer. Additionally, inspect the
face of the dampener for raised lettering
or a “rotation arrow,” which would
interfere with the crank pulley. If present,
sand or grind down the raised lettering.

WARNING: Failure to thoroughly clean
the balancer face can cause pulley
misalignment which will result in thrown
belts.

Attach the crank pulley spacer to the
crank pulley. Insert the bolts through the
holes in the pulley and spacer (from the
pulley side), and place one shim over
the end of each bolt. Loop the drive belt
over the crank pulley and ProCharger
pulley. The idler pulley should be above
the belt in such a manner that it presses
downward on the belt when tightened.

Line up the bolts with the holes in the
balancer and push the crank pulley
assembly up against the balancer. Being
careful that none of the shims have
dropped out, tighten the bolts to a
torque value of 37 ft/lbs.

WARNING: Ensure there is sufficient
running clearance between the bolts
and the distributor (located just behind
the balancer) during installation and
before cranking the engine.
