I bought this use crank pulley for my car but it doesnt seem to match up with the original. I posted in the forsale thread looking for a F22b1 crank pulley. The crank pulley part number seems to be the same for F22B and F22A but correct me if I'm wrong. the problem is that my alternator belt does not fit snuggly around the new as it does the old.

if any can identify what crank pulley the one on the right is, then that would be quite helpful in moving my project along.

 

It appears that they are different pulleys.
Check the larger diameter area where the belt rides.
your original pulley appears to be a 6 groove pulley, your replacement appears to be a five.
Using a narower belt may keep you going, but it is NOT an exact replacement.
