Today I was told that aluminum pulleys will 'glaze' a belt. Apparently the aluminum wears onto the belt when the pulley gets hot and leaves a 'shiny' glaze on the belt which causes it to slip an ruins the belt.

Anyone ever had this happen?

is PSP's pulley aluminum?
JDM?
JL's?

THanks.

 

I haven't had it happen to me, and I have run JDM old style and now his new style pulley.

I can't speek for the other pulleys, but JDM's are anodized alluminum

 

Belt is fine here, too...

 

Isn't anodizing more just to color it? Or does it actually change the strength of the pulley?

Does JDM offer a non-interchanable pulley? (less $$$???)

 

Don this is a JDM pulley... What does it look like it is made of? Steel?

 

what in the world did you do to that pulley?

I can't see that causing the belts to go bad cause allot of the big superchargers out there come stock with aluminum pulleys now.

I haven't had that trouble with my PSP or upper metco pulley .

If anything what we should do is get the pulleys media blasted so they grip better, thats what I want to do to mine next.

 

Slippage, not the pulley material will cause the belt to glaze. I've got 20,000 miles on my PSP aluminum pulley, and neither show any wear.

 

I've got a Metco 1lb upper and a Razors Edge 4lber and I'm still using the original belt with 38k miles on it. Doesn't slip or squeek.

BTW....I do carry a spare.

 

Belt "glazing" is cause front extreme heat and friction....caused by slipping. This is what causes the "glazing". But.....consistant slipping with cause premature wear on an aluminum pulley and a steel pulley. A worn pulley will cause premature belt wear which leads to slipping and glazing. It's a vicious cycle!!!

Jay wins!!!!

 

All of our tuner lower pulleys are made of aluminum. Aluminum, in and of itself, won't cause glazing. If your OEM type belt is slipping, gat a Goodyear poly Gatorback belt and then don't worry about slipping or glazing.

Good Year x 2 = no slippage & no sqealing.


Jeff's Lightning,

JDM's interchangeable pullies have anodized ALUMINUM rings.

 

SVTmoonshine,

Anodization is actually an Al oxide layer (which will occur naturally), but done in a controlled environment. Also, Al oxide is much harder than bare aluminum (its actually a saphyr crystal layer). So, the surface hardness can be determined by the anodizing process (how thick). Dyes can also be added during the process.

I'm not sure to what extent our tuners are anodizing thier pullies. But, like you, I suspect its mainly for aesthetics.

Any tuners want to respond?

That pic ture is not an interchangeable. Notice the rust on the pulley?

 

Thanks for pointing out the obvious.

 

Your welcome..
