4200 F1 Clutch - buy a new one or try a remanufacture?

[Jezbraker]

So a euro spares clutch is going to run me around £1,100 it seems.
Taking my existing one and having it remanu'd is £650 - including the flywheel skim.

Been digging though the forums and apart from the PEGA stuff doesn't seem anyone's tried just a stock remanufacture.

As I'm a DIY'er I'll be doing the swap myself so if it I did go the reman route and it didn't work out I'd be out of pocket the £650 and some scraped knuckles rather than this plus the k or so labour costs... so with that in mind shall I have a punt and see if a reman one is a real option?

As far as I know rebuilt clutches are not reccomended for cambiocorsa/F1 - every rebuild I know of has failed... Probably because the actuator is too savage with the clutch.

Rebuilt clutches are a lot less likely to fail in manual cars unless you regularly track it and have a 200 shot of nitrous oxide running through your drive train like a certain forum member does lol

My personal view is go for new. Tangs on some batches have been known to fails and given the time it takes to do a clutch would you really want to save a few pounds that would hardly cover a weekend away.

If you want to invest some time into this, try kicking Valeo's door in and getting them to supply the OEM part direct but good luck with that, seems the Maseraffia have still got their knackers in a vice!

Buy a new one you tight g1t . Or refurbish your old one and then replace it with a new one when the spring tangs fail .

I have a refurbished unit on my Cerbera/Maserati . I bought used unit and refurbished it, now 20k mls later no problems.
I've done the same on my 4200GT btw and so far so good.

Both manual cars, right? I’ve not heard of a CC car that has had it done and worked well. Mad dog clutches who did them previously wouldn’t touch a CC clutch to my understanding.

It's exactly the same unit just the way it's operated is different. One is hydraulic operated by foot and the other hydraulic operated by TCU

What I'm trying to say is they're both manual. CC and manual I mean

You are right, it comes down to the adaptability of a human foot / leg vs a computer program. When a computer does it, it expects a certain amount of friction for a given movement of the release bearing. When a human does it, there is a feedback loop in the drivers brain that changes the rate of engagement to suit. The challenge as I understand it is how much slip occurs as the clutch engages.

Is this how thread drift starts.....?

I guess someone would have to give it a go and see on CC car. If it won't work due to electronic brain being not able to use it , that refurbished unit can be reused on a manual car.

If you read the thread- the sense is this..
It has been tried in CC cars , and it has never been seen to succeed...
Draw your own conclusions...

 

[FIFTY]

There are a few threads on here and ML about people who tried and failed

Also I know of a failed restored MC shift clutch on a Granturismo.

 

[Wack61]

IIRC it'll have to be trailered to somebody with an SD3 to set it up once it's fitted so I'd make sure they're willing to do that if you're planning on fitting it yourself

There are several people over the years who've thought it would be a good idea, and should be easy. None of them stuck around to demonstrate success. Nor did their sponsors. Of course that may because they were so ****** off with us all saying 'It won't work'

Or not

You're not the first. I'm sure you won't be the last

Aye. Quite a lot of work to get the re-furbed one in. Then quite a lot to get it out and a working one in.

Maybe fine if your labour is 'free' otherwise roughly £5600 for a CC clutch change with a used spare for a manual.....

I've seen these fail over time, (at for example 50% wear) often due to diaphragm breaking, I've had one in that broke the internal springs of the plates too. (cracked inward towards the spline-shaft)
This is the reason non of the bigger parts suppliers or experienced specialists recommend them.

That said often customers aren't aware they've had refurbished clutches fitted, I've encountered that a few times here in the shop. (i'll not point fingers)
So yes fun idea, major pain if the clutch fails halfway trough.

Same is true for resurfacing flywheels, they are very light and thin from the factory this isn't a normal setup.
I've had shops send over cars for clutch calibration with "refinished" flywheels and having to add extra PIS with SD3 to compensate, that's just asking for ether a warped flywheel with a year or two or having it go "beyond **** point"
