Would you explain the difficulties a bit KiWi? I've got the Van Pelt rebuild kits and have started taking mine apart. It will take a good bit of soaking just to get one of the springs to slide out. The other wasn't too bad. I'll have my son press the pulleys off at his shop and press the new shafts in. It seems like the threaded body part should slide off leaving just the shaft in the pulley, but mine don't want to come off. I'd hate to miss something critical.

I just discovered a cutaway view of the pump that explains why the pulley, shaft, and housing all have to be pressed.
