Found it!1. Crankshaft Fit Internal diameter has been honed to a minimum OEM tolerance. In many instances, this will create an excessively tight press fit. Carefully measure your crankshaft snout diameter and hone the bore of the damper to give a .001/.0015 press fit. This operation must be performed with the utmost care as too loose a fit will cause the damper to move and damage the keyway and too tight a fit may cause the damper to gall and weld itself to the crank. We highly recommend the use of an anti-seize compound since the steel hub is not as forgiving as a stock cast iron hub.
