ASP Idler pulley saved me big $$$$$.
As many of you have experienced , our S/C idler pulley`s blow out a lot! The larger S/C crank pulley ,also speeds up the process, by spinning the stock idler a lot faster than stock.. This idler is held on by one long bolt, and must flex some under load..
If this pulley breaks, you are SOL.. You loose both belts and car will be un-able to drive.. At best, parts fall on the ground and do not sling threw the hood of the car or cause other damage.. Most of all, this idler pulley is sold as a set by MB for close to 400.00 bucks!!
Signs of a bad idler are squeeking noise at start up and wobbling when you twist it with your hand..
I sent by stock pulley to ASP and they machined up a new heavy duty Idler pulley out of billet aluminum. They said bearings are now Z rated wich can handle higher RPM than the stock bearings.. I left mine clear coated silver but custom colored anodizing can also be done..
PIC 1 ASP idler pulley with stock bolt cap
PIC 2 Stock pulley and ASP pulley
PIC 3 Install pulley
BTW, this is a 10 minute install or Re/Re.. It is that easy!
Cost $125.00 for a one off but should come down as more order..

Exotic-metal55 bro...I flipped this thread (and the link with the pics) to my mechanic/fabricator friend whose been working on these cars for a while ...he said "It looks like a quality made part. Now for the bad... If you look closely at the the stock pulley, there are small directional blades built into the inside of the pulley. The sole purpose of this, is to direct airflow over the pulley bearing of the S/C idler and the main idler pulley directly behind it. This air flow is crucial to the longevity of both bearings and pulleys... I think with some more machining put into the part, it could be a great part. The next thing to check for is if they used the ISO specs for belt grooves and depth..." ...do you have a point of contact at ASP I can get a hold for more details? I am also interested in the tensioner you mentioned in your linked thread, that can be a point of weakness with time I would suspect...
thanks for your help...and your innovative thinking!
