I bought a remanaacured pump and the press on pully that came off my old one is to big , it slides right on, no need to press it on. This is the second one like that, how can i get it to stay? i just put the pulley in the freezer hoping it will shrink, but i figure it will expand again as soon as it gets hot, any ideas guys?

Thanks John


Oh btw its a late 70`s gm pump.
