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?

Cant you mashine a spacer for the pulley you have and space out everything 1/2 inch ?

SS 1/2 inch round and drill it so it fits between the crank and pulley ????

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

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

At least not until May.......lol....... call me in the office when you get a chance.....

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?

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.
