Can't figure out why I keep tossing belts. Looks like my water pump pulley is pressed in too far. What do you think?

Check it out here

I was seeing that right, it looks like the crank pully is what is in too far. You could put a spacer behind the crank pulley (you'd have to make it) or you could get a different w/p pulley that sits back a little further.

The pulleys must line up!! That is why you are tossing belts.

Question

I think I have read where rebuilt waterpumps tend to not have the pulley mount plate pressed on to the CORRECT or FACTORY depth which makes this pulley alignment problem.

You can press it farther in or out to fix it or space your pulley's whichever one is easiest to do..

Isn't there something like three factory length waterpumps b/c of the outlet leg lengths and the pulley plate being different?? I know there is short and long legged ones...

yeah the z28 has a short water pump, but maybe i can pull the pulley out a bit. or i might just make a spacer - don't feel like removing the water pump again

Yes, there are three lengths -- short, long, and Corvette

Years ago I used the set from Mr. Gasket (is this 'Spectre' now?) and I think the ones Speedway - http://www.speedwaymotors.com/xq/asp...qx/product.htm - sells are the same.
Canton Racing also used to sell misc. spacers for many applications.

Once a belt gets thrown, even if you fix the alignment issue, it will keep coming off. You have to get a new belt. That's how it was with me anyway. Dacco Top Cog belts are by far the best I have used.
