Clutch Shudder

Hey boys, I seem to have a major problem with my newly installed T5 conversion. When in first and moving from stand still my clutch is shuddering pretty badly. I cant think why as ive had a complete new clutch kit installed. It appears to shudder more if i increase rpm. If i let it idle and release the clutch real slowly, it doesnt happen. All i can think of is maybe the flywheel might need machining. Any ideas???

Brent

Re: Clutch Shudder

There was a thread recently about the firewall cracking, thats what it sounds like to me, though I don't have much mechanical knowledge.

Good luck, hopefully it's just something minor.

Re: Clutch Shudder

I assume the clutch kit included a new pressure plate so it has to be the flywheel. Even .005" of runout will cause the clutch to shudder. It never hurts to take the extra time to pull the flywheel and have it machined to ensure you don't have to do the job twice.

Re: Clutch Shudder

also you should drive it nice and gently for at least 500km after you put it in - its the same as if you were bedding in brake pads - you didnt thrash it straight out of the box did you?

Re: Clutch Shudder

Probably needed maching but it will do this if there is any oil or grease on the contact surface area. It MAY go away...Or get better ...

Re: Clutch Shudder

I will assume it is not a pbr clutch as they no longer make for xr8's. Therefore if you installed a Daiken clutch then you will possibly have shudder problems. I have had shudder problems with a recently fitted clutch with the flywheel machined. Daiken have admitted having problems with clutch shudder for xr8's. They actually have sourced another clutch kit to solve the problem and thus you need to find out if you got the old or new type. Apparently in the past they used an asbestos coating which can no longer be used - having trouble with alternate materials. Should machine flywheel always with new clutch kit.

Re: Clutch Shudder

when you installed the gearbox did the imput shaft rest on the cluch plate
if so the cluch plate may be warped (bent) and will never get any better
the gearbox should be fully supported untill its bolted inplace
if you let is rest when its not bolted it may ward he clutch plate
ask a pro about it and see what they say
i have never fited a t5 before

Re: Clutch Shudder
