New Clutch Judder

[marinabrid]

hi all,

mk 1 s reg 98 tdi

had new luk brand clutch and slave cyl fitted by very good mechanics after doing 145,000

fitters said its fine now, driving home form cold start i noticed some judder in 1st gear and a little in 2nd

as got hotter after around 7 miles judder seemed to dissapear,

do new clutches take a bit of time to bed in ? or why would it judder just when cold.

i checked the roll restrcitor, seemed fine , all bolts ok,.

thanks ,

I bet they didnt skim your fly wheel? its like fitting new pads ono damaged disc, you get feed back and takes a while for them to bed into shape.

As your car had 145k on old clutch and is diesel i would be 100% confindent your fly wheel would not be as smooth as it should be. It should wear in but may reduce life of new clutch. I would take it back and get them to skim fly wheel and refit clutch.

if that is the reason then i will have to hope it beds in, the fitters were two diesel fitters at the bus depo who im pals with, they did it as a favour for

Just hold the car on a hill for a few seconds using the clutch. Has worked for me in the past.

I would give it a day or two before I would start to worry. There are a few reasons why it may be juddering, they are: damaged or faulty springs in the driven plate, the driven plate sticking on the splines, a faulty dual mass flywheel (not that one is fitted to your car), oil contamination on the faces and a sticking release bearing (unlikely).

 

I have never had to re-face a flywheel, so I doubt that is the problem, but a clutch does have to bed in a bit.

Certainly sounds like a bit of oil on the plate. New cover probably had a thin coating to prevent corrosion. Should just burn itself off.

thanks for all advice, 4 days on it seems to have stopped juddering, wonder if this clutch will do 145,000 , the same.
