Hi Ruairidh - yes the grub screws are slightly in-set at the back so no chance of fouling there.  The thing does move, but you literally have to push with over 50kg of pressure to make the clutch move ~2mm

Have you fitted double clutch springs? If yes, I have run into the same symptoms. The cause in that particular case was that the inner springs became coil bound in situ almost immediately as demonstrated by compressing an inner and outer set together in the vice. Cure was to abandon those particular inners.
If you haven't fitted double springs then sorry, that's not it!

Hi Stuart, we haven't fitted double springs no, but thank you for your post.  We've tested the 'springiness' a vise and clamps and it doesn't feel excessive and we double checked they are correctly aligned.  Do you know if the Thrust Bearing is supposed to be permanently connected?


It almost feels like we're missing some kind of Lever to amplify the force of pushing the thrust bearing?

I have recently fitted new linings to Borg and Beck driven plate and restored the cover plate by fitting grub screws which have nicely restored the worn section where the toggle levers bear on.This seemed to be the answer but now, some 600 miles later, i am back struggling to get the car into gear without graunching.
The grub screws ( quarter inch bsf) were centre popped and filed flush at the back so that is not part of the answer.
Looks like I’m going to take the gearbox out again but before I do I should like to have some sort of plan ( mice and men etc)
Any suggestions?

Charles

Maybe a little overly simple but certainly worth a 5 minute check - Have you checked your pedal hasn't slipped on the joint on the gearbox (sorry dont know the proper name) to the point you can no longer get full travel?  I only say this as in the desparate attempt de-clutch ours, this did happen.
Thanks for that very good suggestion — Charles

If you are using a three speed thrust bearing in a carrier with slots for the toggle levers self evidently it is permanently engaged. If a four speed thrust bearing, no.

Which are you using?

Thanks Stuart. Ours is a 4 speed and the thrust bearing has no slots. Will make sure it's adjusted appropriately!
