Clutch shuddering

[Mateusz]

Hello everyone,

Just got a quick question about my newish clutch that I hope someone can help me with. I got my clutch replaced about 2 months ago and since replacement there has been shuddering on take off. It's not major and I can only feel it when I take off with low rev, about 1500rpm, and only when the car has warmed up, after about 10 mins of driving. The clutch is perfect when cold but shuddering begins once it warms up. I did ask the mechanic about it and I was informed that the shuddering should disappear after about 2 weeks as the clutch wears in and might not be exactly aligned, if that makes sense.

I got the flywheel machined as well so could it be that it's not done properly and causing the shuddering? Now I'm not sure whether I should just wait and see if it does eventually disappear as it wears in as I am generally gentle on the clutch. Also, just one last thing, there's vibration in the clutch pedal when I press it down very lightly during driving in every gear. Does it seem like it could be a flywheel alignment/balance problem or clutch or something else? What do you guys think?


Cheers,

Matt

Try bleed it there might be air trapped in there somewhere.

Mine shudders a little and I am guessing clutch has been replaced

I wonder if it was factory dual mass (never shudder) and has been replaced by normal flywheel and clutch - can do a little shudder

What clutch got put in.? Brand

It may be a flywheel machining issue, clutch plate/pressure plate issue, or bearing issue. Maybe a part was faulty but not recognizable visually.

If they did change to a single mass flywheel (obviously not since you paid for machining of the existing flywheel not for a whole new one) then it would be the most likely cause.

Other than that I would say something was not refitted correctly/ done up to the correct torque.

welcome to exedy non oem from japanese warehouse only replacement.

Deal with it. or replace with stock pressure plate.

Most probably if the replacement clutch was an Exedy they have been getting some bad reports as to shuddering and vibrations. It seems that they have some quality issues that were not there a few years back.

If the flywheel has been machined and no other changes have been made to the OEM setup I would be looking at the clutch assembly, namely pressure plate, clutch plate etc.

Hope this helps.

I had shuddering with my old, worn out original clutch.
I have NO shuddering at all with my new Exedy HD clutch.

no shudder from my tough as nails Jim Berry uint

could be fluid/ oil on the flywheel.

when it happens, do a couple of hard, slippy launches and see if it clears/ burns off the oil.

my old GT Fozz did the same thing from a weepy rear-main seal.
I'd just launch the thing a couple of times and it was fine for another hundred km's

Cheers for the responses. The clutch I got put in was a standard one. I think I'll just leave it for now and see if it does eventually stop because it's nothing serious. Again, thanks everyone, I appreciate it.
