Default Clutch Saga

DW10ATED RHS 2.0 307

I had a new clutch fitted last week, and I've been having a problem with it since. It's been a ball-ache of an episode, I'll briefly explain;

- Bought a clutch kit from ECP, told mechanic I bought correct kit for my car and DMF

- Mechanic took everything apart, only to find flywheel had been replaced with the SMF conversion kit

- Found clutch kit for SMF conv. flywheel

- Put everything back together.

Now, as I took the car away, when the car is stationary, the engine/gearbox judders significantly as the clutch bites, and it's much worse when facing up hill (or downhill when in reverse).

Took the car back to the garage, and he said that it could be the driveshaft.

I needed the car for work, so I took it home and had a mate look under the bonnet whilst the clutch was at biting point. He was saying that the engine was jumping back and forwards when the clutch was biting.

Took back to the garage the next day and asked the mech to have a look, and to check the mountings. He said it was fine, but the O/S driveshaft was on it's way out, and that he thinks the juddering could be the flywheel. I was told to persevere and allow the new clutch to bed in with the flywheel.

Before the clutch was replaced, there wasn't any juddering or violent shaking. The SMF was running true with the old clutch, as there are no signs of uneven wear on the old clutch plate. The only issue was the friction material was glazed slightly.

The juddering and shaking has settled slightly since I first took the car back, but it's still there.

I'm not convinced that a driveshaft is causing the shaking, which was the mechanics first diagnosis. I could only think that if it was, the splines would be jumping out of the grooves in the clutch plate, but that surely wouldn't cause the engine to rock?

If the flywheel is warped, then would this show on the old clutch? And should it not have been spotted when the clutch was taken off (I work on Boeing aircraft and rule of thumb is to inspect mating parts when removing components)?

It's bothering me now, and I need to get it fixed. When starting off from stationary and facing up hill, the clutch struggles to engage as it feels like it's bouncing off the flywheel, and I need to give it close to 2,500 revs when facing uphill to get going.

Any ideas?

i did ask before what kit you had.

there is something about wearing them in but with this engine you can tell if theres a problem. i would be looking at the release bearing it will make the mounts go wild

heres mine

Because I didn't know the car had previously been converted from DMF to SMF, I left the mechanic to source a kit for the flywheel, he said he used a Valeo kit, based on what he took off.

I agree that the symptoms feel like the bearing or pressure plates, but because I'm asking myself loads of different questions, I'm tying myself up in knots. I've still got the old bearing, and that looks OK to me, so I wonder if the input shaft is making a meal of the new bearing.

I'll have a look through your thread now Monty, cheers mate

In fairness, the clutch feels beautiful when the car is in motion, it's so much smoother and happier going through the gears. Just setting off from standing makes me cringe!

I keep thinking if it is the right clutch, but he's claiming he did a like-for-like swap. I've got the old clutch, so I can always compare if it doesn't clear up once it's all bedded in.

Having read through your thread, the general consensus is the release bearings are questionable - although yours was a LuK...

I'll give it a bit longer and see what happens.

This is the old bearing after a good old clean, I notice a bit of wear where the fork sat, but it still runs freely and clean. I also notice it's identical to the standard bearing in your thread - I wonder if the new bearing differs from this and is causing the issues?

If there is a judder when the clutch starts to bite and takes up drive its the clutch plate or pressure plate at fault.Why? could be a number of things,faulty manufacture of the pressure plate diaphragm spring?,bent clutch plate? wrong size clutch? it needs removing for inspection.
Its nothing to do with the release bearing,all that does is operate the clutch.
A faulty drive shaft would only vibrate under load,when the car is being driven in gear under power.
Trouble is jimmy all this is non standard,a recognised conversion yes.I cant help feeling though what should have been done is to have fitted a DMF and clutch listed for that model so getting the car back to its original Peugeot specification.

Are you sure he sourced a valeo kit? only asking as I have mine to do after getting stuffed like a thanks-giving turkey by Mister bloody Auto. I have sourced a Valeo kit, its the KIT4P it even comes with a sticker to apply in engine bay to inform you a that a conversion kit fitted.

I believe you must replace like for like with these conversion kits (so I read) they don't like you swapping parts around so having said that it might be worth insisting on the proof of purchase?

I also read that a crankshaft seal can cause judder if its getting oil onto the clutch?

I'm not sure what I can help with as Im out of my depth here as I'm yet to do my own so might have to be paying for Monty's time when I drag him over to do mine

good luck
