Thanks everyone for your advise on the pump. I'll just replace the whole pump. The existing pump is, according to the previous owner, about 2 years old. Since the pump has the keyway, perhaps it came from Mr. Hervey. I don't really care at this point. The machined pulley looks in great shape. The pump spins freely. The shaft must have been cut off because there is no threaded hole in the end. Everything was working fine until this problem came up. It's just that much less $$ I get to keep when I sell the car. Thanks again, see you all in P.F.
