I've had an exedy clutch and lightened flywheel fitted and I'm experiencing bad clutch judder when setting off and down shifting. Done about a 1000 miles in it and it's still no different.
Anybody got any ideas, is it clutch, could it be fitment??

 

Ive got a tiny bit when pulling away but nothing on downshift or anywhere else, its an exedy organic on a 99 type r. Standard flywheel btw.

 

I think its a feature mine does it too

 

This is an archive thread from my local forum, hope it helps
Clutch Judder - Surrey Scoobies

 

see if this helps///// CLUTCH judder refers to the vibration that is felt throughout the vehicle chassis at the point when the clutch takes up drive. Often the sensation is a violent vibration, so aptly described as a judder. The clutch is a mechanism used to gradually apply engine power to the driving wheels.

The clutch consists of two friction surfaces that are gradually brought together so that as the friction between the two surfaces is gradually increased, the amount of power transmitted is also increased as a result. Eventually sufficient pressure is applied to both surfaces that no more slip occurs and all engine power is transmitted to the driving wheels.

The clutch consists of three major components – the clutch bearing, pressure plate and the friction plate. The bearing bears on the pressure plate; the job of the latter is to gradually apply pressure on the surfaces of the friction plate and the flywheel.

Judder occurs when one or more of the clutch components have worn, failed or become misaligned. When this happens, “slip” is not constant, but rather the surface of the friction plate engages the flywheel at certain points along its periphery, hence creating the juddering effect.

 

As it's only 1000miles old, there could well be a fair bit of "new clutch" friction disc dust impregnated onto the friction surfaces. Have you been quite gentle with the clutch up to now? Give it a couple of fast starts using around 3000rpm to burn off the deposits.

^^^^^^^^agreed........worked wonders for mine

 

hi mate i'm experiencing exactly the same as you. i've done about 4 k miles and still no better. I need to pull like 3k revs everytime i pull away which is rediculous, and also does it on the down shift. been told its because i've got the 6 spring clutch plate and the 4 spring is the one to have...bit hacked off, got no choice but to buy another unit although this time i will be doing direct through the garage rather than supplying myself! i've found you can minimise it by blipping the throttle on the down shift ....still a pain though

 

It does make a diiference if you launch it a few times, and i mean proper launch........

How long it will stay not juddering is anyones guess

 

Whay car is it on? I have an 06 2.5 and mine judders unles I set off at about 1800 rpm and it judders a bit in second if its below 2000 rpm when I shift.

 

If a couple of 'proper' launches does not cure it it may be the clutch was not aligned correctly when fitted.

 

as above mine juddered until i launched it a few times, been fine ever since.

 

Hi ya,

Can someone tell me exactly how to do a good set off to eliminate clutch judder. I tried a 3000rpm in first gear and dumped the clutch and the just joted off lol.

 

5500rpm or higher and then dump the clutch that should do it.

 

Slip the clutch or full out?

 

full out! slipping the clutch will only glaze it and kill the flywheel

 

i have the same problem with my subaru,its terrible especially when sitting in traffic

 

I will try the dumping the clutch at 5000 rm on the way home tonight, it wont damage the transmision will it?

 

lol yeah, only had the car a few days and it feels wrong reving to 5000 and just dumping the clutch lol

 

If it will clear the problem I will do it lol, guess it will be a lot of smoke and a lot of noice lol

 

Didnt get chance to do the 5000 set off but did do a lot of pumping the clutch in 3rd gear at 20 mph and its 70% better.

 

Mine deffinately was aligned as i used an old input shaft.

Plus the flywheel was skimmed

 

Yep mine does the same.

excedy clutch. judders on pull away and shifting down..

 

Just have a big jolt going into second now like the engine mounts arnt good enough

 

did you people supply your own clutch or get the garage to supply and fit?

 

Fitted my own, seems to me like it depends where its sourced, as my mate got one from a different place to me and it feels totally different.
