Well, I'm in a jam here. I'm changing my power steering pump. I've got the pump out but I can't figure out how to get the tang that's on the pump shaft off the pump I took out to then put on the new pump. It obviously fits over the shaft; there's an internal hex in the shaft but there are no external threads on the shaft. Is the tang part pressed on the shaft? Should I get a new tang and how would I install it on the new pump? I appreciate any help.
