I was able to move the IP sprocket by taping on it lightly with a hammer and die. The IP sprocket did move when I applied tension to the belt.

Good. We should still try to see if the IP internals can rotate thru at least a few cycles. Can you walk the belt off? And then try rotate the IP shaft via a wrench on the sprocket pulley nut? I wouldn't use a hammer and punch to try to move it further, seems like too much of a shock.
