Jesel belt drive
Anyone running a Jesel belt drive on there big block!
I need to know how much the balancer is moved outward from the block because of the thicker crank gear "belt drive gear" if at all, for belt and pulley alignment.
I called Jesel and he said he thinks its 1/8 inch but I need to know exactly how much, not to good of tech if you ask me.
Thanks :
Tom

I have one on my BB but not gm block. I don't know exactly how much the damper sits out. But I did have to space the water pump out by .120 to clear the back of the mech. mezier pump.
If it helps I could measure from the face of the block to the front of the damper? The damper is a ATI unit. Or a more useful dimension?
Running a March serpentine setup. The alt. is mounted where most have their power steering pump at. Down low, drivers side.

Do you have a mechanical pump, if so then I assume that the .120 also includes how much of a spacer you added to the lower pulley for belt alignment?

A measurement would be great, I have a Dart block and a summit racing supercharger damper. I also have to shim out the water pump a little, waiting on my summit racing order to see how much.

Mine measured 3.122 +/- .010 from the face of damper to the front of the block's machined surface.

Hope this helps....or even makes sense.

I have the Jesel and had to make 1/8" spacers for the water pump to block and behind the lower pulley. A waterjet works great for cutting the spacers. I may have the file I created for the waterjet to use to cut them if you need it...no guarantee though.

THANKS, it must be close to 1/8 inch as said by Jesel.
Thanks d555 for those measuements, yes they help.
I will call The Blower Shop and tell them the specs to get my blower ordered
