looking for early type clutch, and starter motor anyone?
Discussion
i ve been told the bellhousing is the newer model, and i have machined the srew heads from the flywheel. In order to fit the new clutch i d have to machine the flywheel as you point out. However i think the earlier clutch is much better. Its lighter for a start and at least to my car its been more robust than stories i hear from other owners. The first time it went was at 22k. I got the friction plates resurfaced in greece and its still going strong.
Now 7k later im starting to make provisions for the second rebiult, hence the request for friction plates.

thats interesting, from what i know there are only two manufacturers of clutches. the original AP supplied by TVR Power and the clever trevor one. Is your something different? would be interested to know
No idea to be honest, never saw it directly - ordered and sent to the chap fitting it for me.Give them a call, I'm pretty sure it's not the race proved one as supplied by Clever Trevor
Been there, done that. You will need to replace the flywheel (or get the old one machined so the clutch recesses in about 5mm), as the newer clutches are thicker.
Contrary to what some say, you don't need to replace the bellhousing though. The allen-head bolts that hold the clutch to the flywheel will foul on the bellhousing only by a couple of mm, so you have to chamfer those heads so they're tapered slightly.
Ensure you order a new slave cyliner with the clutch.
My new Raceproved clutch is no heavier than the old one. And on my old 4.2 the new clutch was, if anything, lighter than the original.

not exactly, my flywheel is not flat but it is machined where the bolts are, still it needs skimming off to make the new clutch fit. of course im not sure about other cars with early clutches. Maybe my configuration is a bit strange. Flywheel very similar to the new one but thicker, bellhousing and slave cylinder for the new type clutch and an early clutch. TVRs.... go figure!

maybe you are right Andy, but when my clutch went in greece, i ordered a new slave from CT and new clutch from Power ( i thought that was heavier but cant remeber exactly).
Anyway after unsucesfully trying to fit the new clutch (we even machined the bolt heads of the flywheel but not the flywheel, my mechanic did suggest that but i was unsure), my mechanic just resurfaced the old friction plates from my origincal clutch, and off i was with the new ct slave on.
The surprising thing was that we didnt know the correct thickness of the friction plates and i went along with what my mechanic thought (he d never seen a tvr before or an AP twin plate clutch) but his instincts were right and its still working fine. All for 300 euros!!

Some conflicting and untrue information on this thread. If you have an early bellhousing you may have to replace it to fit a later clutch (to be fair there are so few of these around nowadays that it'd be most unfortunate if you had one) . If you have an intermediate bellhousing you only need to reduce the length of the alloy nose where the slave fits, fit a shorter slave and taper the clutch bolts to get it to fit. If you have an early flywheel you need to core the centre out to clear the friction plates cushioning springs. You may have to reface the flywheel, there's different depths of step between the flywheel face and the clutch pedestal bolt sections. There is no one clutch which will fit in place of everything. There's also some oddball clutches with a different thickness iron ring between the two friction faces. it can be a minefield!

thanks for this Jools, my bellhousing is the later type. I know this as when i was ordering a clutch i gave the part number to TVR Power and was told its the late type. Hence i ordered a new type slave and clutch which didnt fit. When i them gave my clutch part number to other indies they couldnt find what it was. But when i did my engine rebiult i was told my clutch was an early type, however the friction plates do not have the pressure springs. So i think it is one of the oddball ones. I gues i will find out when the time comes again
