Here is a pic. Also figured I would post in this thread. Does anyone have a stock tensioner pulley that would sell me. As you guys know mine was bent a little and I dont want to shread another belt. All i need is the new pulley not the whole tensioner kit. Thanks

It’s tough to visualize from that picture. Know you tossed a belt recently.

How does it appear with the engine running? Does it manifest itself with any untoward tensioner machinations?

hamann69

I think i tossed a belt because my tensioner pulley was slightly bent due to installer error.

If we can assume it’s square and straight with the other pulleys, it could be out in either the ellipsoidal or tangential plane. Since it is already installed, visual observation of its dynamics is a worthwhile diagnostic troubleshooting step.

My evosport dampened ODPS spins up with nary a wiggle. ymmv.

Any competent shop can put a dial indicator on it and tell you if it is bent.
I doubt it is bent though, the larger problem is that the ASP is welded on and so many things can go wrong during this process related to concentric alignment. Also the pulley could be key bound, installation problem.

I would really have reservations about the shop you are using if they bent the tensioner pulley and did not tell you. Then to let you drive the car like that, there is a possibility the SC belt can take out the other belt and wham no power steering, crash. Then they fess up to bending tensioner pulley and they don't replace it WTF. You claim that you were sure they torqued the pulley as per the instructions, are you still sure?

Im gonna bring the car up to renntech and have it checked out.

Are you certain that the tensioner didn't get bent by the belt on its way out?

IMO, the ASP pulley needs to be checked as well. A very small misalignment can cause bis issues.

hamann69

Na I know he bent the tensioner pulley he told me when he took off my old belt he bent it but didnt think it would make a difference. Obviously it did.

I still say it's just that damaged pulley being way out of whack. Wish you didn't have to buy the whole pulley assembly. I say pop a new pulley on ASAP before any more damage is done. Maybe check with Rbrenton like someone else mentioned to see how cheap you can get it.

Yacht Master

Wise move, Ask them to check the run-out and alignment on the ASP and tell them the story. I would take the Stock pulley with you in case they find a problem with the ASP. That way you will have a choice, stock or Renntech.

BTW they do have the special tool to torque the crankshaft bolt.

hamann69

Im not sure about a special tool to torque it down but he says it was torqued to spec. I know they had to bring in a special pulley puller than they did.

Looks like the section where the larger ring meets the OEM pulley seems warped/wavy... is the rubber damper filling not perished or torn? Does not look right to me.

You need to see how she behaves under load ... sometimes spinning it in neutral does not reveal the problem.

Another thing is how do you damage the tensioner pulley? That takes more than some brute knuklehead effort...

hamann69

They used a prybar on it to get the old belt off. Under big load there is still some viabration I feel. Tomorrow im having a MB mechanic look at it.

vrus

A prybar???

Why not just lift the tensioner up with a wrench and pull the belt off by hand?

THat pulley is damaged.. Dont use it.

hamann69

My asp pulley is damaged or the tensioner pulley? They used the prybar on the tensioner pulley.

vrus

The ASP Pulley is damaged.. How did the lip bend like that? Its almost like it was damaged before install (dropped or something) and then put in the car.

The picture you posted is of the ASP pulley so that is the only thing I was commenting on.

hamann69

Wow well that explains alot then. It defently is bent I can see it by just look at it. I guess that might be causing the viabration im feeling.

Were are you located in Fla . I might know of a competent shop , GOD I could have done better on my Garage floor, Oh well ,the damage is done lets not do a repete performance. Lets see if I can help. Regards ___PTEngineering.

With that bad of an install Hamann, I would be keeping fingers crossed and/or be offering up some prayers that those idiots did NOT damage that crank key or you just bought yourself a brand new bottom end.

Only way we'll know is when they pop off the crank pulley.

PTE is the man. He'll hook ya up.

hamann69

I really hope they didnt damage anything that would be horrible. What what they have had to do in order to damage the crank key? Is it an easy thing to damage?

hamann69

update- I had my car checked out today by a certified MB mechanic and he says the pulley is install fine and it looks like there not wobbling or anything. I showed him the viabration I was getting and he felt it. When we got back to the shop he checked my motor mounts and turns out one of them is completly shot and leaking. Also the tranny mounts are worn aswell. So I guess that is whats causing the viabration I was feeling.

Jakpro1

Thank youuuuuu!! Thank youuuuu!!! (jakpro1 bowing)

Still think you need to replace that bent up and fixed pulley though bro.

If you get the new mounts and she shreds another belt, you gotta pay the cash and get the new part.

MRAMG1

You the man

GOOD call

See yeah
