Clutch problems
Discussion
I just sold my Cerbera today to a really nice chap from Birmingham - hi Martin, by the way, if you're reading!
Anyway, typical bl
dy TVR, after virtually 4 years worth of sterling service, only broken down once, it actually breaks down once he's got it home!
Apparently the clutch pedal is quite easy to press, and it's impossible to get it in gear. The car has always made a bit more noise when the clutch was disengaged (foot down) versus engaged, and the current theory is that this was a bearing which has just given up the ghost.
Any ideas chaps/chapesses? I feel really embarrassed, especially since I just sold him the car today! Any advice would be appreciated!

We had a similar thing happen when the slave(might have been master - cant remember)?? cylinder seal went. Have a look at the clutch fluid for the usual tell tale signs, cant remember the costs involved but at the time our car was under warranty. Perhaps it might be worth contacting Joospeed? Although hes quite busy at the moment (sorry Joolz!!) he might know of a fix.
Good to have another Cerb in Birmingham - it'll be the fourth car AFAIK in a similar colour. Why is Birmingham so blue????

Thanks for that - funnily enough when he called me tonight I guessed maybe it was something to do with the master/slave cylinder. Not that I know anything about how clutches work, you understand! But for it to completely fail, made me think that something had suddenly gone rather than the clutch actually expiring.
Anyway, i've recommended that he give Joolz a call in the morning anyway. What he doesn't know about Cerbs isn't worth knowing; i'm sure he'll have an idea. And there's an easy way to beat the waiting list - Jaffa Cakes and blackcurrant i've heard, but shhhhh, keep it quiet!

Ours just went overnight, it was its usual heavy self but five or six hours later when dad got in to go to work the pedal was just really really light and it wouldnt get into gear!
Will remember that queue jumping tip, although we tend to just book it in months in advance! Have been known to bribe him with a Smart drive in the past too
Poor Joolz is pretty overworked most of the time, I guess its his own fault for being the superb specialist he is. Check my thread from a few weeks ago.

If theres oil/fluid near your pedals, then it'll be the master cylinder and not expensive to repair. If theres oil under the car, then its the slave. If neither, then it could be broken fingers on the diaphram spring. As was with mine.

I know what the noise is on your car marc (sorry, ex car) .. it's the floating flywheel bit between the two centre plates, the three spring clips aren't strong enough to hold it firm after the relined friction plates went in it .. that's not the problem here though. sounds like BCA said, fluid loss overnight. bummer. will calm the new owner down and try to gte him sorted asap for you.
PS ben .. did you go M1 way from my workshop the other night? .. trying to work out if it was your smart I went past at (insert big number)mph teehee.

Can you clarify the situation on early clutches.
I always hear they are expensive and parts hard to get,
How true is this and why?
Go create some weather...

Sorry to hear about your troubles Marc.
Must admit its something that bothers me every time I take the car out now. I know Joolz changed the slave seals on my Cerb prior to me taking delivery so hopefully...
Appears to be topic of the month at the mo.
Out of interest Joolz, do the seals fail due to a scored cylinder or just down to the fact that the slave cylinder's the weakest link in the chain (or a combination of both)???

As I understand it:
You cant get 4.2 clutches anymore so you need to move to a 4.5 style which includes new bell housing? Therefore expensive.
I believe that some people have managed to just get the clutch plates re-lined.
But I could be totally wrong.
I think that's about the gist of it. All I know is that it cost a fraction of the cost of upgrading to the new style clutch, and it's been perfectly fine for the last year or so -up until now
. But it sounds like the problem with my (old) car may be unrelated to the old/new clutch question.

the slave cylinder seals are all the same, so if it's the seals you've no probs, just the labour involved.
sometimes the cylinder itself is scored and that requires a new cylinder.
you can't get early clutches anymore, you have to fit the later deep clutch basket with friction linings that have drivline vibration cushioning springs in them. because the clutch is deeper you need a shorted slave cylinder, sometimes you need a new bellhousing on early cars, and the flywheel needs to be the latest version with extra depth machined into it's centre to clear the friction plate springs.
so:
all cars on early clutches that have worn friction linigs can have linings replaced, no guarantees given though on that.
cars with early clutches and broken pressure plate fingers must have complete new clutch, flywheel and slave cylinder.
cars with leaking slave seals and good cylinders can have seals replaced.
cars with early short slave cylinders which are scored need later cylinders, clutches and flywheels (ouch) unless you're lucky and find an ealry slave somewhere.
Later cars just need the relevant broken bit replacing since all later car clutches are interchangeable.
for this purpose early cars are pre 1999.
and car made 1995, 96, 96, 97 and some of 98 are on early clutches.
all first 4.5 cars are on early clutches, changeover sometime in late 98, exact date unknown.
all SP6 cars on the later clutch AFAIK.
hope that helps.

Nah, wasnt me, I keep a look out for TVR's top down at midnight - didnt spot any! anyway -couldnt you tell if it was my car or not? Perhaps I need a more distinctive colour scheme - or perhaps a numberplate that says more than just my name
Did wait a bit to see if you would fly round that little round about as you leave the workshop, but dad pointed at the clock and grunted -so had to head home at (insert not very big number)mph.
see you soon - miss the Cerb already

Thanks a lot, this was the information I was asking for in another thread.
