Great. Now I've got it jammed on tight! Stupid me. Never thought to check the measurments before I put it on. Cleaned both surfaces with fine sandpaper and started winding it on. Probably damage it trying to pull it off. Hmmmmmm.
Bought the new pump from PSC and it turns out to be a '73 and up deal. So no keyway and bolt to hold it on, just a press fit deal. Then had to get a new pulley as well. You know the routine!
