After my recent issues with destroying a timing gear set, I decided to go with a Jesel Belt drive. I have to say, the kit fit perfectly and was a breeze to install. The problem is, my circulator water pump hits the belt. Before you say go with a cross over, I cant, I run closed cooling. I need 1/2" additional clearance, easy enough to do with either a 1/2" spacer or the long style water pump. BUT, what the hell do I do for my stock Merc serpentine pulley? I looked around at pulley manufacturers and found nothing that would work. I happen to have a pulley from a 575 SC ( thats not mine ) it has a 1 1/2" offset from my pulley. That would work with either a 1 1/2" spacer, or the long style wate pump but Merc gets over $200 for that pulley. Anyone have of a better solution?

Here's Johnny

Use the 575 pully......so what if it's not yours..... oh wait nevermind....... lol.......

Vinny P

Yeah... They're yours. Maybe you wont notice one missing?

Your pully fell off and rolled under that table over there and I can't find it anywhere. Damndess thing I ever saw. Oh here it is, how in the heck did it get get 1 1/2" narrower in that short off a roll. Sh!t happens I guess?

I ran into the same problem. Solved it. Question: What block do you have? GM Dart Merlin other? Do I assume that you have a Hyd roller cam?

Vinny P

I have a Dart Big M , running a solid roller cam. Any help would be great.

Somebody probably has a take off one from an upgrade to a crossover system and more hp.

Vinny, Is there room to move the pulley back 1/2", or will it hit. Say you find a pulley that is 1/2" deeper, or you use the 2" deeper pulley that John loaned you, and you put a 1 1/2" spacer in the pulley, Will the pulley rub on the body of the water pump?? Just a thought.

My combo is a GM block, hyd. roller cam. I thought that I could directly help, but not so. Let's try the long method. Here is the pump that I am using.

I believe that these are the smallest spacers they have. I used these spacers from CV Products. I only needed .200, so using double gaskets would make the .250 spacer even larger. So, I had the .250 CV spacer machined for O rings.
