This is what happens when bad mechanics try to remove a panhead oil pumpwith out taking the key out of the shaft! Obviously the pump would have less pressure since there would be a gap between the feed and return sides of the pump.


Here it is with some metal put back in it. I didn't have time to machine it out today. I dropped it off to get painted on my way to straighten out a 46 and a 48 frame, and a whole mess of front ends. I will post more pics of the set up and finished product later.
