I just had my clutch replaced 2 days ago with an ACT HD pressure plate and street disk. The first thing I noticed is that as soon as my foot touches the clutch pedal, there is vibration right up until the clutch is disengaged. The other thing I noticed is that there was tons of chatter and I had to rev it almost to 2K rpm to get it to even start out without shaking the car. Well I put about 200 easy miles on the clutch and the chatter is still there, but it's not as bad. The vibration hasn't gone away though.

Anyone know what is wrong, if anything, and what should be done to correct it? Please only professionals or people with first hand experience with this problem, I don't want a thread full of guesses

Thanks!

 

i just got the act install last week.i only put about 150 miles on it so far.the pedal vibrants a little when first engage.i also thought i hear some chatting but i think i'm triping.hope this shaking of the pedal goes away.bump for same question

 

I did notice a slight faint rattle in first gear after ACT clutch install on mine. Now it's all good. Drivetrain noise or throwout bearing noise increased though. No vibration though.

 

I need tips and I also have aluminum flywheel so please help me..

 

I was using the act for a while, however i used the 4 puck

Chatter and vibration were the worste ive ever heard

drivability of the clutch sucked

lead to the destruction of my transfer case


conclusion: get the best clutch you can, supersoft on your driveline is the best way to go......besides, you have enough traction

 

I contacted ACT's tech support, as well as having the clutch shop inspect my car.

ACT said the chatter should subside with time. They were confused about the pedal vibration, and said maybe it's torrisional? vibration. They said so long as the shop torqued the bolts down correctly in the correct pattern, I probably have nothing to worry about.

The clutch shop said I probably just have to change my shifting habits to avoid the chatter (slightly higher rpms from starting). They said all my motor/tranny mounts were fine, and if ACT didn't think there was anything wrong, then it should be fine. I'm going to consider this problem as solved unless I have more trouble down the road.

Thanks for the input!

 

Iodine23 had the same problem... I forget, but I think the PP was not torque down properly.

 

Sounds like a job for RRE's no-name clutch.

 

I've used ACT in the past with Honda/Acura's. Never get racing clutch's on stock tranny. I've blown many trannies with ACT. I personally think chattering is a norm for ACT clutch's.

 

Never used the ACT, but maybe it needs to break in a little?

 

My biggest concern with the lumpy pedal feel is that the release bearing may not be clipped in properly or damaged the retainer crown (or whatever you call it) upon installation. We issued a new tech bulletin a few months ago (similar to Exedy's) that warns of this. If you are also having disengagment problems that cannot seem to adjust out at the pedal I would be even more suspicious.

 

maybe the clutch need to break in a little more. i noticed the same vibration problem in my uncle's car to. maybe the release fork or throwout bearing is rubbin on something

 

Was the flywheel resurfaced?

yes it was resurfaced with zero step with a diamond cutting lathe.

 

Wow ok I wasn't worried, but now the president of ACT is posting on my thread so maybe I'm worried again. I have no disengagement problems, but the chattering isn't getting any better with time. The pedal vibration is still there. The chatter mellowed down a little from the initial severe chattering, but it is still there. Can you please point me to your TSB? I didn't run across it when visiting your site in the troubleshooting section.

Thanks for the input, that's why I went with ACT. It is a very rare company indeed that is going to have the president posting on your thread when there is a problem
