Good day guys.
Anyone know if the final drive belt and pulleys widths, have to match?
As in, could I run a 1 1/8" belt on a 1 1/8 trans pulley and 1 1/2" rear pulley?

 

no, but you can keep the stock trans pulley and run a 1 1/8 rear belt and 1 1/8 rear pulley

 

Why couldn't you run a 1.5" rear pulley with a 1.125" belt? There's a little space there anyway. Seems to me like it would work as long as the offset was OK, that is, the belt lined up on the pulley without hitting one side or the other. If the belt is centered, that's only 3/16" on each side.

 

I think the belt needs the proper width at the rear pulley to keep the belt from walking the trans pulley can be left as is

 

Thanks guys.
Looks like I'll be getting a pulley made, to match this wheel.

It's only money,,,,,,,,, right

 

If your present pulley matches your wheel, take a good look at it. Usually the inner flange can be removed. Once you do that it is pretty simple to machine it down. We've done several of them for our customers.

 

Na, going big wide, John. Going from 16 X 3 to 18 x 8.5 with 240 tire.
Have to go 1 1/8 belt, but finding a matching pulley, in 1 1/8th has'nt worked out.
Found the matching pulley on ebay, for <$200 on ebay, but it's 1 1/2". Having one made is over $600.

Already have the wheel

 

You can still machine your stock one down and use it until you can find/afford the right one!!

 

I'd probably buy that $200 one and cut it down..

 

That would be an option there Greg.
I'm sure my stock pulley wont work with the new Performance Machine rim. P.M uses a 2 1/2" hole, for the pulley and rotor to fit into.
