400 Clutch fork problem
Discussion
An unusual clutch problem, Replaced the entire innards of the clutch including upgrading the release arm for a strengthened one (TVRQ005), new slipped pads and a new (plastic) release bearing. All the parts look identical (Except the release fork) to the ones that came out.
All goes well for the first 300 or som miles, then the clutch goes completely solid. Took the clutch apart and the slipper pads have slipped through the end of the release bearing, chewing up the release bearing in the process). The set up looks a little odd, like the release arm is about 5 mm too long, and the pins that the slipper pads pivot on are past, or at least level with the end of the track that the pads run in, thus resulting in the force being put right on the end of the track which clearly limits the life. Thinking I've been unlucky I order another release bearing and put it all back together again. The setup appears to the the same, I'e the fork looks like it's a little too long. But----I can't see anything wrong so it must be designed like that, put it all back together and this time get 10 miles before the fork again slips off the release bearing. I'm am going mad!!! I wouldn't have though it possible to make a level too long - They're pressed steel. Any ideas????

To my knowledge I haven't....I rebuilt the gearbox replaced the clutch, master cylinder etc. with new, replaced the release bearing with the same as I took off, but new, which was plastic.
Fork dimension is 81mm from centre of cup (where the pivot bolt engages) to centre of the slipper pins. I think this is about 5mm too long. Does anyone know of a shorter version available?
