Belt rubbing water pump

Appreciate the pics kuda. The double-groove alt pulley - this was an AC engine but the PO removed the AC and I guess just hacked together a pulley set-up that would work. Sounds like that's a common thing people do.

Also, clearly my alt. mounting is NOT the same as what you have, so I'll probably replace that. Mine just has a single pivot on the "engine side" of things, which means there's really no way it can be tight enough without a ton of deflection.

So my question is, is it worth it to just replace all of the pulleys and brackets to have the right set-up? I assume the water pump isn't bad but how tough is it to swap out a crankshaft and alternator pulley on the car?

It's not that bad at all (to change the crank pulley). Sometimes the pulley sticks to the damper, but a few good whacks with a rubber hammer will break it loose after the bolts are out. 6 bolts and the center bolt will get it off.


I bought repro alt brackets and alt from Mancini. they carry the alt, alt brackets, and pulleys. As I cautioned before, check the water pump pulley for flatness on the back surface right out of the box if you order one new.

Price check the brackets and pulleys between Mancini and bouchilon performance.

I liked the Bouchillon bracket set as it comes with all of the bolts and spacers. I think that mancini racing doesn't have all the bolts like bouchilon.
