Hi all,

 

I am venturing under the z tomorrow to see if I can find a reason for my clutch riding (sticky linkage perhaps) before I commit to a clutch change. I wondered if anyone had any top tips of places to check?

 

Cheers

Rob :cry:

I need to re-familiarize with clutch operation, when the pedal is depressed, hyd fluid transmits force to clutch plates separating them and when released the springs pull the plates back together? So if the clutch slips with the pedal released then its plate and springs that are worn or perhaps a linkage preventing release. However if it were a sticky linkage I would feel something through my foot and once it has freed it shouldnt slip the clutch again until I depress the pedal again (pls no comments that its you I'm depressing).

I could do with some confirmation of this train of thought since money is a little short.

The car had a new clutch 20k miles ago.

clutch surface by the sounds of it

 

it wont be a sticky linkage, does the clutch smell when driving hard, and does it slip all the time or in a particular gear

 

signs of worn clutch are normally

 

slipage at high rpm/ if low rpm then its shafted

gears crunching especially 1/2

burning smell

high clutch bite

 

as chris said you could try ajusting the pedal so master cylinder pushrod is longer this in turn with apply more pressure through the hydraulic systym thus adding more energy to the clutch fork. But i think by the sound of it the clutch is knackered

Thanks,

its any gear, give it too much gas at low rpm and it rides, has got rapidly worse, no gear crunching mind. I tend to take it easy to prevent the slip but yes it will smell if I let it ride. Regards High clutch bite, not that Ive noticed but I'll investigate.

20k out of a clutch? I've only put 2k on the clock so can not say how it has been driven really but Is that a reasonable figure for a clutch? What about hydraulics? Is there any way that air ingress can cause the same symptoms only I experienced a little clutch ride about 1500 miles ago and after bleeding the clutch I had no further problems although I did put the ride down to a lazy left foot at the time (a little weight left on the clutch pedal), I have to agree though, the writings on the wall and an order from Smithy is around the corner.

if its slipping, no matter if there is is some air in the line. I would almost 100% say the clutch is fubard, 20k is not alot but perhaps the flywheel was not skimmed and it may eat a clutch plate much sooner!

 

also might be worth checking the rear oil seal is not leaking and spraying on to the clutch/flywheel as this can also cause a slipping clutch

The service history states the flywheel was skimmed and it was a £243 clutch kit in 2002 (whether that is a indication of a good/bad/mediocre clutch I dont know).

 

If the rear oil seal is leaking would it find its way out of the bell housing?

 

Rob

there is a small access hole between the bellhousing and the engine, you will know if the seal has gone, as the bottom of the gearbox will be wet with engine oil

 

and £240 sounds like either a cheap paddle clutch or an OEM kit, id be happy with 20,000 miles on a clutch TBH but average life should be 40-60k miles
