New clutch is "pulsating" on friction point.

Postby Willstar » Fri Jul 13, 2012 9:51 am

Morning!

I've finally got my '01 NB8B back together.

I've installed a new clutch (Exedy MZK-6964HD) & rear main seal, and had the flywheel machined. Everything was scrubbed clean and (Almost) everything was torqued back up.
It grabs nicely on acceleration, but it has a vibration/shudder when slowly releasing it, like when slowly reversing.

I've done plenty of clutch changes on other cars, and never felt this before.

Someone please tell me that it is more likely to be the new clutch bedding in, and not a high spot on the flywheel or a warped plate. I havent got enough skin left on my knuckles to pull it all out again! :cry:

Mine did that (exedy HD) for a while after install. It's imperceptible now after a few hundred km.
