This happen a while ago, maybe a year ago, I have been out of town and had no access to a computer. I will post a picture of the pulley as soon as I can soon. What happen was I was driving down the street then out of no where a heard a loud metalic noise and nothing worked all of a sudden. power steering etc. I am very glad I was on the street. I pulled over looked in my engine bay and noticed my CRANK ODPS pulley had shattered. I had the power steering pulley shatter years ago and evo sport took care of the problem. This time I had the car towed to evo sport, they informed me it "was do to the age of the pulley" i was in shock. the told me the would fix the problem, for a price. when i came to pick up the car I was handed an invoice for around $1200.00 dollars. Which I had no choice but to pay. Simon offered me a new dampened pulley at a discount... which i believe was $700 Installed (dont quote me on that because i do not remember exactly what the quote was, but it was something around that) I still even though it has been a while since the incident, when ever I think about it I am in shock and stunned about what I paid for the issue and how the matter was taken care of, which I believe should have been taken care of by evo themselves. I will not play the name game but I have had other people (former employes) tell me the same thing and it was a metal defect problem. Till this day I have never heard of a pulley SHATTERING due to age like this, which by the way i believe the first set of pulleys went on my car 8 years ago. which again was replaced after I had the other pulley shatter on me while driving a while ago , which they took care of. come to this about it other than me , i have never heard of a pulley shattering into pieces. I mean in no way to put anyone down by posting this , but i feel I should let other people atleast know the possibility.

 

To this day I feel I should not had to pay for the problem. Or EVO Sport needs to tell everyone of their customers with the odps system on their car it can brake and they will be held liable for any costs from damage there after and they will not stand behind their product.

 

That's pretty bogus IMO. How on earth can a pulley shatter?

 

Did Evosport install the odps? If not, the installer may have over torque the crank pulley as Evosport specifies the solid crank pulley to be torque to 85 ft. Lbs.

I never heard a crank pulley shatter either.

 

Evo did install it. I just moved, I'll find it asap and post a picture. If you don't believe me, feel free to ask EVO
, and this is the second pulley shatter. Try the search feature for the first one

 

I saw one of the AMS pulley shuttered last year, sure it may happen, its some kind of bad install or losing screws or not seated

properly, i hate it when i saw it, soooo HORRIBLE......!!

ZAYED,,

 

I believe you. Wasn't being sarcastic, just never heard of a solid Evosport pulley shatter, my ignorance.

I wonder if it was metal fatigue due to the undamped nature of the solid pulley due to resonances.

 

Never heard of Aluminum getting old either. If this is the case then no one should be manufacturing pulleys out of it. I would like to see a picture as well.

I know the waterpump or ps pulley was recalled because it was designed with too many lightening holes that it was not structurally sound from new. The crank pulley is solid.

 

^ Aluminum DOES get old. Not old in terms of age, but in terms of fatigue. Materials Engineering 101.

I'm surprised they didn't use steel, which DOES have an endurance limit (stress threshold below which it basically lasts forever)

http://en.wikipedia.org/wiki/Fatigue_limit

 

Aluminum pulleys do not last all that long, they are not as good at standing the wear. It is one of the downsides. A proper dampened steel pulley will last forever. I do agree if they made a faulty product they should honor it.

 

+Agreeeed.......

ZAYED,,

 

Yes and no............my stock crank pulley failed with only 47K miles earlier this year. Lucky I caught it before the belt came off and did some read damage. Harmonic balancer was toast, caused the pulley/belt to move 1/2" forward.

 

Maybe the aluminum will wear faster on the belt surface but aluminum should not fail from fatigue when it is not flexing. No aluminum pulley should ever be sold if they will eventually fail.

 

Absolutely zero trouble from my dampened Evosport ODPS crank pulley after 40,000+ miles.

Replaced a few idler, guide and tensioner pulleys along the way, but they’re known consumables.

 

Anything and everything can fail. Not many people have aluminum pulleys, almost everyone has a dampened steel one. The % of failures is negligible for the oem pulleys, the % of failures for the aluminum ones is also very small but much much higher in comparison. I am sure hundreds of people on the boards have never had any problems with them. The fact is the risk of failure is higher and most people are fine with that. If I chose to buy one I would happily accept that risk and enjoy the benefits they give while hoping for the best.

 

Good input,,

why missing with a heart of the Crank balancing...!?!,, i think no one need to spend $$$ with risky & headache.......!!!

ZAYED,,

 

NMM, was your crank pulley the solid design or did it have a hole pattern milled in it? Just curious as mine is the first set they ever made in 2002 and it is solid with no holes.

 

it was the solid design I believe second gen, I am sorry i have not been home yet to take pic's , i will as soon as i can

 

Sorry someone near me died. I will post pictures asap
