Belt rubbing water pump

danielb927 said

I guess my real question is, do I need to worry about the alternator pulley, or will it be close enough? Since the alt works, as far as I know, I'd rather not have to buy a new one just to get the right pulley, but I don't have easy access to a press to change just the pulley either. So if I swap everything else and leave the double pulley, can I shim the mounting a bit to get things aligned?

I've seen many people run the double pulley without the A/C hooked up. The belts are slightly off front to rear, but will still work. It may wear the belt more with the extra side load, but you may be able to get away with it.

I think that you should get the proper double groove pulley at least to get the diameter smaller for the pulley around the crank to help your clearance with the water pump.
