Gearbox noise dissapears when pressing clutch pedal [UPDATE]
-> Solved 206 Problems

As title says.
Rattling noise (ball-bearing?) but my mech recons it's not the clutch release as that would make noise when pressing pedal.
It was also replaced along with the clutch plate/disk about a year ago (genuine pug).

So what is it exactly?
Cheers.

Mine did this for ages, and my gearbox went Monday.

OK, where exactly is that?
Is that on the crank-shaft?

same as the release bearing, mine does it too. and used to to it on my 106 until i couldn't bare it anymore so had the clutch and release bearing changed.

Damn.
Not pleased if it's this as it was fitted new and genuine about a year ago.

It's logical to expect the clutch release bearing to make most of the noise when depressing it as that's when it's under load but it can rattle in its cage when fully up and can squeal when worn and under very light load when pedal is fully up

Sometimes if you pull the clutch lever on the gearbox even fuller back from the rest position and the noise stops then you know what it is for certain

So are you saying it could be the release bearing even though it stops when pedal is pressed?

Not pleased if it's this as it was fitted new and genuine (Valeo) about a year ago.

Yes, especially a loose rattling in its cage or a squealing when cold which lessens as it warms up

A rattling or chattering is just that though and they have been known to stop doing it on their own as the release bearing is just catching at the rest position. Try pulling the lever back a bit further and see if it stops then you'll know and you can show your mechanic

How can I pull the lever back if the clutch cable is preventing it?

Also, it only stops when fully depressing pedal and only does it 3 out of 5 times at varying level of noise.

Cheers for replies all.

The cable should never be pulling so tight that there is no slack at all at the lever when pedal is fully up

206 clutch cable

OK. 'Will check. Thanks.

Clutch cable are self adjusting due to the design of it (self adjusting mechanism) U better dun touch it, once u remove it, will be pain in the butt to put it right again.

I am sure will be the bearing for the clutch cause i have similar problem and it gone when i replace with complete clutch kit.

After u warm up the car or drive for some distance will it get better?

Now don't make the guy paranoid Very Happy
No one said anything about removing cables, just checking for the 5mm or so of slack which the self adjusting cable should automatically put into the system. It's how you check that the cable's been installed and adjusting correctly

my bad... i worry he will remove the cable

Thz for the info on checking the self adjusting cable.

You're right though that if you disconnect and release these new type cables then it's game over and a new cable is required

OK, checked makes no difference.

I'm now thinking, could the fork be not sitting on the two 'notches' on the release bearing
and allowing it to move-around?
This would make some sense as I think it started doing it when the clutch kit was fitted,
and mabe there was a slip-up on re-assembly.

The clutch works but feels a bit different compared to Mrs.V9977 (exact same kit fitted)
Like there is a gap where it suddenly bites. Confused

[SOLVED]

By far the biggest (/expensive) problem I had with the pug.
Horrible noise (like a helicopter on some occasions), making me look and feel like a total prat in the car.

Gearbox re-conditioned due to suspected primary shaft bearing about to go.
Clutch was fitted perfect. - Twice (second time replaced the whole set inc. release bearing)
None of the above made the slightest difference.

The problem was the bolt guide bushes (collars) between engine and gearbox were distorted,
so when the gearbox is fitted, it is not perfectly aligned (input shaft) with the disk and
consequently the flywheel > crankshaft.
Also the left-hand side transmition rubber-mount was tightened to prevent weight of the box 'pulling down' on the engine as it were. (there was slack in the middle bolt which has no spacer tube unlike BE4 boxes)

Worst part was replacement guides were included in the MA overhaul kit, but we did not think to use
all of them (on the engine-gearbox join).. Stupid.

The problem is described in this Valeo document ( www.valeoclutches.com/...edalUp.pdf ) section 2.

Seabook came up with it a day after problem was pin-pointed and solved. Evil or Very Mad
Lee (even though no-one likes him) relentlessly sent info-flash and Pegeot documents helping a great deal as usual. Smile

[UPDATE]

Having now addressed a crankshaft issue ( www.206info.co.uk/Foru...art=0.html ), it seems that this was very much the main cause of this problem as the remaining small noise has suddenly completely disappeared. This makes absolute sense if you read the post immediately above regarding crankshaft-flywheel-clutchplate centering.

What a waste of time/energy/money this has been..
