Default Vibration after clutch/flywheel install - 06-20-2016, 06:47 AM

Hey guys,

I just had a new clutch (Spec 3+) and SMFW (mfactory) installed in my 335i and I'm getting some unexpected vibrations around 1250-2250RPMs. The vibrations happen in every gear. All of this has been putting around town as I'm still breaking in the clutch. Is this normal? Has anyone else experienced this? Is there some kind of solution?

LOL, welcome to the club. I do not think this will improve, I have vibrations 1800-2600rpm, that are bearable and vibrations on 5th gear, from 2800-3400rpm, that are unbearable. No solution so far.

You should get the clutch and flywheel balanced as an assembly before installing.

This is why on some all-in-one clutch and flywheel packages, like an Exedy multi-disc, there will be markings to show a proper orientation for install.

I've read of people having this issue after a clutch job. Oftentimes the center bearing was spun around 180 deg during the install, causing the vibration. You can spin it back to the right orientation and the vibration will go away if this is your issue.

How will we know the correct orientation?
