So I did exactly what your not supposed to do and tried turn the motor with the belt. A few days later I received my new crank pulley but the collars were different. Not a big deal I machined it to mach but why are they different? The 2 tangs are opposite of the pulleys I see available from suppliers. Mine I would call a "male" and the suppliers a "female".

There are many different aftermarket crank pulleys made--- the model A was a big market for "improved",and cheaper parts, the originals are all one piece, the 2 piece ones are for quick fix

Your broken one is an aftermarket one.

The die cast one that broke is the cheapest one, some had die cast sleeve too, they wore out quickly, I have one of those pulleys on my smiths compressor-- it broke, I got a replacement the same from 1$ pile

Several years ago we did a review of the pullies and none of the two-piece ones were good. I think Snyder's is having a better one made now but we found the one piece was the way to go for the fewest problems.

There's a 2 piece pulley, that screws together with a L/H thread & looks stock. I've used them.
Just slide out the old pulley, cut it off with a Saws-All, pop on the new pulley & you're DONE!
