xantia hdi clutch

Hi All
My xantia had the clutch changed a few months ago ever sense has had a bad clutch judder worse when cold, recently i have noticed that the biteing point seems worse when cold and juddering once warmed up i dont notice the judder hardly.
the clutch that was fitted is LUK i was told.
also the clutch pedal is about an inch hugher than the brake pedal,was before the clutch was changed.
Do you think i could have a hydrolic fault causing the judder ?

Hmmmmm HDi 110bhp, they are Hydraulic as you say and also a PULL type - similar to the ole XUD TD...

The clutch pedal should be level with the brake, but not sure what would cause it to come higher then that...

I would have thought a failling slave cylinder would cause a pedal to drop - not lift..

Sorry I cant actually answer your Q... theres some Activa/2,1 td drivers here, these engine's useing the same clutch setup, they could answer you better..

1" higher than brake pedal is normal for a Xantia clutch pedal. Need to know if 90 or 110 BHP to confirm hydraulic or cable actuation.... TBH I doubt this is having any bearing on clutch judder. Was a complete new clutch fitted not just a pressure plate, and was it a new clutch, not a recon one? Sounds to me like there's a fault with the clutch, or it got contaminated with oil or diesel during fitting. Who fitted it? Not a high street chain with name Mr "drive-disengagement-device"

was it???

Im YET to see a Exclusive 90bhp Richard, Im certain ALL were 100bhp's

It seems the owner is sure its hydraulic too asking if he has a hydraulic problem.

Of course, I can still be prooved wrong..

FWIW, (probably not a lot) when I bought my 90Hdi it had full service record and the previous owner had told the (main dealer) garage that he thought the clutch was duff. Their written comment was that it needed a new clutch. Instead he traded the car in.

21000miles later, still seems ok to me. Only comment is that it seems a little stiff. I am aware that I should keep an eye on the clutch clip, but I'm reluctant to fiddle with it.

Should the 90Hdi clutch be ultra-lght?

the 90bhp is a CABLE operation, so you will have cable drag, and release arm nylon bush wear, as it uses cable and Push clutch...

I dont think it should be ultra light, but it cant be as light as a 110bhp hydraulic one...

Hi
the car is 110bhp xantia with hydrollic clutch !
It has had a complete clutch kit as i said its supposed to be a LUK i got the old clutch back as i had never seen a pull clutch and was interested !
The old clutch was a LuK,the old clutch was worn out and the edge in particular was worn badly ?
the bloke who fitted the clutch says my flywheel is warped causingthe judder.

Did it judder before the clutch change? (Maybe it's not centralized properly?), but I'm sure it would be worse at speed..the judder.

And, if the clutch fitter noticed the flywheel was warped, why not change it,while it's in bits? Be like bunging some warped brake disks on, and wondering why the brake pedal's pulsing,surely!!!

Can't see it being the hydraulic side,it's quite simple,unless the pushrod isn't seated in the cup,(in the bellhousing), properly?.

"also the clutch pedal is about an inch hugher than the brake pedal"

I'll check mine later,(the wife's out in it now..) and post back.

Hi
The mechanic has only said the flywheel is warped after i went back to him saying how bad the judder was,it didnt judder before it was changed but the bite was right at the top of the pedal.
i am concerned the clutch will wear far too quickly due to the bad judder, when the car is cold the judder is really bad but once warmed up properly the judder is 95% gone !
I did wonder if it could be maybe the input shaft oil seal leaking ?

Unfortunately there is probably only one way to find out what the problem is, and that involves removing the gear box again....

If it was't doing it before then it seems unlikely the flywheel is 'warped' (I can't see how it can be anyway - have you seen how thick it is!??!!). Possibly the face is not flat, but that should have caused judder on the old clutch. I guess there's a possibility that the old clutch wore a bit funny (you said it was worn on the outside) and that the mating face of te flywheel is not flat, hence causing the clutch to grab a bit.

Sorry for the delay,

been busy with xbox 360's / x clamps!

I've checked my pedals,HDI 110 1999:

The clutch pedal is indeed around an inch higher than the brake pedal,
and the accelerater/gas pedal is around a quarter inch higher than the brake pedal. Been like that since I fixed it,(new clutch),ie,fine.

Oil leakage sounds like an idea,as mentioned, could a seal have been damaged,getting the 'box back on? (I'm no clutch/gbox expert).
Can't see it being the flywheel; as said,bit thick aren't they...do they wear out?!!
Not that DMF jobby is it...as the 110's don't have one?

Hope you get it sorted,and please report back if you have, informing us of the cause/cure.

Dave.

The bite point on the hydraulic clutch is pretty much right at the top (one thing I don't like about it).

Ask the clutch guy what gearbox oil he used.

Hi
I have written the part about the flywheel wrong what i should say is the guy said the flywheel probably needs re facing as its no longer flat.
I am really ot sure what to do as i cant afford to do it all again and i dont want to do it myself either !
i have the old clutch as i said i think the top of it is worn more than the rest maybe i could put a pic up if i can work out how !

there's a thread on how to post pics, basically upload them somewhere like flickr and then put the link to the pic in [img ] [/img ] tags.

I would like to see a picture of the worn clutch plate as I don't understand what you mean by its more worn at the top?

Forget warped flywheels & needing refaced, I think a cheap or defective clutch has been fitted.
