Part 4- more Australian Muscle Parts (AMP) Belt drive cam timing kit. Mock-ups

I was checking the crank pulley installation, and noticed it would not go on all the way. My Callies 4.500” crankshaft has a large 2.150” OD at the location in this picture. Several people checked other crankshafts and some were about 2.00” OD and some were 2.15” OD. Most factory Chrysler crankshafts were about 2.00x” OD. If you have a crankshaft with the large dimension, the AMP crank pulley won’t clear and won’t go on all the way since it’s recess is 2.045” ID. I put the pulley in a lathe and bored the recess larger (2.163” ID) to clear my 2.150” crank. The outside of this part of the pulley is only for the AMP lip seal.
