need some help here guys/EVOsport,

on my way home yesterday and all the sudden the battery/alternater warning came on, lost the power steering, and watched the water temp quickily overheat. I pulled off the freeway thinking "WTF" and guess what I found? The idler pulley to the lower left of the supercharger broke off and the belt came off.

Now I didn't buy this kit new of course, so I'm not asking to replace this part for free cuz you guys probably wouldn't do that anyway. The previous owner had it on his car for 20k miles and I had it on mine for 25k miles. This lead me to question the quality of the part, or I'm just unlucky with a faulty bearing. I do need to purchase another idler pulley ASAP (Sunday), so I can get my car back on the road. Right now the car is sitting at a local firestone shop near the freeway exit I exited last night (thank god someone my parents know owns the shop).

so whoever at EVOsport sees this please contact me asap. I will also give you guys a call tomorrow.

here are couple pictures

wonder if this will happen to me...hope you get this fixed soon.

Vadim @ FD

Looks like bearing seized up.

Frank go to any auto part store and get a 70 mm outside diameter, 17 mm inside diameter 6-rib flat tensioner pulley. If they have 7-rib in stock even better. This will work until new one gets to you from evosport.

If you have any other questions call me until 8 pm.

FrankW

thanks Vadim for the quick response. I'll check out the auto parts store before I can get a hold of evopsort on monday (looks like they're not open on sunday as I thought they did anymore).

another member that's had a problem with the Evosport ODPS...

makes me wonder about the quality of these...

FrankW

the grinding noise on the supercharger clutch bearing just started recently as well. at least I have the extended warranty and a good service advisor for that.

How did the belt look after the pulley failing? Do you have to replace that also?

FrankW

the belt looks fine from what I can see. I'll probably replace it anyway tho.

BIGjohnny

Have Evosport look at it. They should replace the part, might cost you an arm and a leg for labor. I'd be ****... do some *****ing =)

Moviela

From the picture it looks like the bearing cage failed. Looks like it is simple to install, just one bolt. I am curious Frank, looks like I can see the inner race, and there is not a speck of grease or oil. How did that happen? Did the seal fail?

Is it possible that the grinding noise from the clutch caused this backside idler to be overloaded?

FrankW

no idea. should the bearing even dry up that's up to evosport to answer. from the looks of it after the shop took it off the bearing is dry and no grease is present.

FrankW

I highly doubt that. the charger clutch bearing only has the grinding noise when it's not engaged, so when it's engaged the tensioner/idler pulley should work properly as it spends more time engaged then not.

as to why the bearing seized up it may have been due to it is dried up, but this leads back to my earlier question: should a quality bearing even dry up and causing this?

Cappa26

EVOsport you should replace it if not, charge you for a fraction of the price a new one to replace it.

But yeah, labor is gonna hurt.

Are these the greasless bearings and I still thought all bearings had a cycle life on them no matter what.

Eurocharged Rick

why is everyone so worried about the labor?

it is one bolt to change the idler pulley and a couple more to get the belt back on...should take all of 5 minutes

FrankW

picked up the idler pulley. took it to the shop. waiting to see what happens. new idler pulley looks different and slightly larger. Simon at evosport said it'll be fine. we'll see.

itsmeek

do you guys have any idea what you're talking about with the labor? or are you just posting here to post? it's a simple fix- the labor will cost .99 cent.

MB_Forever

It will NOT cost you a lot of labor. Should be NO MORE THAN 10-15 minutes.

Main cost is in the part. Evosport should replace it for you...

Hello all, Dale from evosport here. The pulley that was on Franks car was from version 1 of our kit. We have since updated the pulley and have had no issues.

Like any evosport product there is a full warranty to the original owner of our products.

The labor to change the pulley is about a half hour. It involves simply lossening the tensioner, removing the belt and unbolting the idler pulley and then reversing the process.

Good luck Frank I hope all went well

hope my UDPS is alright...

FrankW

thanks for Dale for the help. new tensioner pulley is now on the car. runs fine. the car is off to the dealership for other stuff.

the only thing I'm wondering is that what was the reason for making the newer tensioner/idler pulley slightly larger?

TopGun32

I had the same problem and I had to replace the water pump cover at $400, since the bad pulley stripped and broke off.

I never really made a bid deal about it.



Evosport gave me a new water pump pulley, but I decided to not use the ODPS again.

I also bought the kit used.. so its a matter of time.

Moviela

The larger idler pulley might be to make up the track length so the belt tension is within specs of the belt manufacturer. I am still curious about the lack of visible lubrication. Is the bearing a "greaseless" type?

Eurocharged Rick

yes, they are greaseless...

Vadim @ FD

The difference in pulley sizes is very small.

It is now available from OEM manufacturer vs. being custom made.

That is all it is.
