M. Reed, I will try to explain how to make a puller like a friend has. He lives in Tn. so I can't get dimensions for you but maybe I can explain how its done. Take a hollow steel tube with an inside diameter large enough to go over the pulley hub with the setscrews removed. Mark and drill the end of the steel tube to match the setscrew holes in the hub.You should be able to reinstall it on the hub and put short bolts into the setscrew holes. Weld a piece of steel on the other end of the tube, drill and tap a hole for a jackscrew probably 1/2" or larger will be fine. Install on crankshaft pulley, put bolts in both setscrew holes, not tight enough to touch crankshaft. The pulley should come off with no problem. If this is not clear enough Email me your phone # and I will call and try to explain it another way.
