For some reason after my clutch job during which the flywheel was resurfaced and a Spec Stage 2 clutch installed, my car vibrates more at idle and if I am standing still and raise rpms to 800 it vibrates even more. What can be the problem.

 

Help.

I just had a new oem clutch installed and am experiencing the same weird vibration, that i never noticed before. I was considering that maybe a motormount was installed incorretly....

 

where did you get this installed? in brooklyn or at jeff's? would like to know since I'm going in for a clutch install later today.

 

It doesnt sound like an exhaust rattle does it? I just installed a new oem clutch, and something is rattling. While it was rattling at idle, i just touched it with a screw driver. It made it stop, so im assuming its exhaust.

 

Not exhaust rattle, I did this in Brooklyn for 290 with resurfaced flywheel.

 

If the clutch wasn't centered with the alignment too properly, it will vibrate noticeably. If all the flywheel mounting bolts weren't used, it will likewise not be balanced, but to a lesser extent. Sometimes, if you don't actually pull up on the clutch alignment tool, the clutch sinks with gravity and is not centered, even though the tool is through the center.

 

I wonder if they balanced and centered the clutch

for 290 you could have done it yourself....I WOULD....well, my friend and I are doing that on his MX-6

 

I dont have a place to do it or the tools. I will go back next week and tell them to redo the work.

 

Since I am going back to make them redo the work, I want to make sure its not the mounts and that they installed the clutch disk wrong. If I had bad mounts would hte car just vibrate bad while standing at all rpms while reving or only at low rpms?

 

Why would mounts just all of the sudden get shot after a clutch job? Doesn't make sense. Moreover, the motion of the engine/tranny is distributed over 4 mounts. I don't really think that the vibration would exacerbate with rpm like a non-centered clutch would. With both, it is possible to feel vibration at idle.

 

i think its possible that the mounts could go bad after the clutch job. if they were marginal before and when the tranny was dropped more stress was put on the front and rear mounts...its a long shot but it IS possible. Maybe the tranny mount is only finger tight? anyways, i dont think the clutch disc not being centered would be the cause of problem at this point cause the tranny is on already. it would cause more probs bolting the tranny up.

 

Well I have one front mount that has been polyfilled ready to go in.

 

I kinda question the theory that the clutch is not centered. When everything is together, the clutch is supported by the input shaft of the tranny. The purpose of the clutch alignment tool is to keep the clutch centered to you can slide the input shaft in without trying to putz with it when putting the tranny back on. Plus the input shaft is splined, the clutch isn't allowed anyway to shift around.

The engine mount theory is actually quite plausible. When doing a clutch job, you have to lower the center beam that supports the motor. This puts a ton of stress on the engine mount near the passenger side strut tower, and if the motor wasn't supported right, this can ruin the mount after a little bit of time. That could explain the vibration. However since you mentioned a resurfaced flywheel...there could be a possiblity the flywheel wasn't resurfaced properly, or it could be slightly warped. The other things could be the clutch disc itself is not balanced, or the pressure plate isn't balanced.

My suggestion is since you had a shop do it, take it back to them and explain what's going on. They should warranty thier work, and should fix it.
