Lightweight Crank and Alternator Pulleys
 

Ok, heres the background info first. ;)

I'm currently designing a 2.2 Ecotec pulley for my J-Body community. This will also work on HHR's & Cobalts. I currently have a 2.0 Cobalt SS pulley. I have been told that the only difference between the two are the number of ribs for the belts. I agree with this, but would like to get my hands on a 2.2 ecotec pulley to confirm other dimensions. With out taking it of my HHR. The alternator pulley is currently in production since it is the same as a 2.4L twin cam "quad 4 motor." :smile:

I just really want to know if I can get my hands on a 2.2 crank pulley. Does anyone have one or can obtain one... :poke:

Any comments or remarks are welcomed.

My first option would be to try checking your local junk yard.

Local yards have NONE. :confused:

"Dealer Item" - just buy one from your local dealer (he'll most likely need to order it).

That's what we do when designing new parts. :thumb:

Yeah I can just do that I just do not want a part that I am never going to use again. But worse comes to worse I'll just buy one. :(

It's pretty much the only way with a new vehicle like this, we have had to buy shocks, struts, rotors, rear beauty bar, - all just to get parts to prototype off of. Hopefully you will make your money back in the end...

Got one off a 2004 cavalier. I'll take my fender well lining off to make sure it is the same as the HHR. Hope to have it completely designed by the 4th. :beer:

Ecotec Preliminary update :) Finally NJHK thanks for the pulley :)
