A couple of the members of the ML forum have used the Launch X431 pros mini to adjust the clutch. I just bought one but haven't used it yet.

Buy an SD reader you can't set the clutches KIS and PIS points up without it.

Thank you for this friendly advice.

This would be maybe a solution. Also easymas if it will be avaiable during winter or I could also bring the car to dealer after I´m finished.

So what about my partlist? Anything missing?

Google Craig Waterman as he used to do them on the floor on his back in the USA.
Mind he is fit and did a Great write up on his website.
I can second Launch X431.

Looking at my invoice for clutch job (amongst other things)....

223982 - Gasket £28.90
234953 - Thrust Bearing £354.45
230426 - Flywheel £223.55

As a matter of interest labour for clutch and setup was £1350.00

Total bill was £7991.40 - Jesus......

So, I´m still thinking about doing the clutch job by myself.

So which parts I would need from this drawing?

1, 9, 38

Should no 8 also been replaced?

I would machine the surface of the flywheel and not buying a new one.

What else should be done while I´m doing this job?

When I did mine (on axle stands in the winter) I just replaced the Flywheel and the clutch. I didn't bother with the spigot bearing because it was fine and the thrust bearing appeared ok so I didn't bother changing that either. Five years on, it's still ok.

Unless you know someone who can skim the flywheel, it's much easier to fit a new one.

I bought a Texa system so that I could adjust the PIS point and bleed the clutch. Not sure if the clutch really needs bleeding as it's a quick release / dry break but I wanted to make sure no air was in there.

A lot of bolted on P clips so a longer job than a mass produced car. The biggest issue I had was when tilting the engine to get the torque tube on / off, it pulled the MAF hose off at the bottom (looked ok from the top) so I didn't notice when it was all back together. The car would start, run and then stop pretty much straight away. The helpful Bosch ECU would detect a problem with the metered air entering the engine and stop it without throwing a code. Took a while to track down.

When the shop did my clutch they also replaced the pilot bearing on the crankshaft 235062 (04 coupe) but not the no. 8.

Thank you for this information. Makes absolut sense.

If it fails you have to do a clutch job again.

Was is not possible to move the gearbox or rear axle backwards to detach the tube in front?

228738 is the clutch part # for the MC Strad, the 4200 uses part #196335 which retails for £870 on Eurospares. I’m not sure if there’s a difference in quality or longevity to make the premium worth it.

The point still stands that the clutches for these are way overpriced.

You can recondition your old clutch for £400-500 max and it'll be as good as new if not better

I think this will be of interest to a few people, however there was a big but. Mad Dog used to refurb them but only for manual cars as, I believe, the frictional properties of the new linings meant it didn’t work with CC boxes. Do you know of someone who has done this successfully?

Certainly no one has ever come back publicly and said 'behold my wondrous, reconditioned CC clutch'. Although many have said 'It'll be fine'....

And then never said anything again! But we do know that MD would refuse to refurb a CC clutch.

I’ve seen ads on eBay of a Turkish company i believe called PEGA who will redo them, but that’s as much as I know about it.

I had a quick google, the Lambo forums don’t seem to be big fans of these, but some direct feedback would be useful as they are very cheap compared to OEM.

You need to move the gearbox back to get the back disconnected, the tilting was to make it easier / for clearance at the engine end IIRC

I've done it with mine one. So far 12k miles with no problems.
I have to admit that my engine is mated with manual gearbox but the clutch itself and thrust bearing is from Granturismo F1 .
I've paid around £250 for reconditioning which included
Flywheel skimming
New friction plates
Skimming of the pressure plate
Dynamic balancing
It was done abroad but here in the UK for the same job I was quoted 495 + Vat by Clutchfix LTD
And one more thing my car is slightly more powerful at 480hp and lighter at 1300kg then a standard Granturismo

Yeah, I don't think anyone is disputing it's fine on manuals. The human leg is smart enough to work out the difference. Sadly the CC TCU appears to struggle with anything that does not have exactly the same friction properties.
I say appears because there's not a single know case of someone successfully installing a re-furbished clutch in a CC car. There might be thousands of them driving around, but the owners are very very quiet ;)
