Well, these have lasted longer than the previous ones, but none the less...are ready for changing again...
This will be my 4th set...
First time was basically the lower one that sits behind the large ATI supplied aluminum bracket being reduced to a "V" shape...
Second time was both upper and lower bearing failure, of which the upper had the snap ring break and pulley started walking back and forth on bushings...
Third time which are my current pullies...the lower, again, is wearing out quickly...upper not bad at all...
When I installed this set, which was over a year ago, I also changed my stock idler and tensioner assembly as well as using new ATI idler bushings, which seemed to cure the problem...until lately...
Anyone have any insight on why this one in particular gives me problems? I have read all the threads here and elsewhere...I know others have had similar issues, but is there still no good fix?

 

I never had any problems with mine. Maybe I was just lucky and got good parts?

 

Haven't had any real isues w/ mine. Probably 70k mi on them. My belt is wearing on the engine side though. My ATI idler pullies do show some pretty good wear. Deffinately time for new ones. I think my issue is coming from the crank though. I'll have that fixed soon enough though.

 

No problem here.

 

SCIV...you have a D1SC though right? Is it an 8-rib set-up?

WJ MARK...which ProCharger do you have and is it a 6-rib or an 8-rib set-up?

I don't believe they make an 8-rib upgrade for the truck P1SC...maybe that's the real problem...it being a 6-rib that is...

 

P1SC, I think its a 6 rib, But Id have to go look. Oh yeah I sold it. Its off the Truck now and on its way to Texas to another member on here. I think they all are 6 rib, other wise you have to change all your pulleys on the Truck.

 

P1, 6 rib.

 

problem "solved"...for now...
AWESOME customer service from ATI ProCharger...
