997S.1 Clutch Mechanism Question

[ianwallwork]

Hi everyone,

I'm hoping someone (maybe with access to a Porsche parts system) can help me with a problem relating to the clutch release mechanism on my 997S.1.

I'm currently having the gearbox replaced on my car ('05 997S.1) due to my the original 'box breaking a tooth on 1st gear. Whilst there's no 'box on the car, I'm having a couple of bits and pieces sorted. This includes new RMS and Intermediate shaft seals as both were 'weeping'. The biggest and most irritating problem we're loking to address, however, was a squeaking clutch. Every time the clutch got warm it squeaked at the gearbox end of things as you depressed or released the pedal.

My local Porsche independent has got the clutch in pieces on the bench and for the life of us, we can't find any reason why this should be happening. The cluch plate, cover, release bearing (do you colonials call that a throw-out bearing? :-) ) and slave cylinder were all new about 5000 miles ago. The only thing that looks 'odd' to me is where the slave cylinder engages a 'dimple' in the clutch release arm. This looks like metal to metal contact - the nose of the slave cylinder seems to sit in the 'dimple' with nothing but a blob of grease to lubricate the interface between the two.

So my questios are:

1) Is it correct that the metal 'shaft' of the clutch slave cylinder should engage the metal 'dimple' of the release arm directly or is there supposed to be some sort of hardened plastic part to keep them apart and take the load?

2) Does anyone have the exploded diagram of the clutch release mechanism to confirm?

3) If the above is normal, does anyone have any idea what might make the clutch mechanism squeak?

Hope you can help

I would check the pedal in the interior of the car. A little

shot of WD-40 should help the squeak disapear.
