So!, a combination of a misfire and a less than sympathetic driver who slipped the clutch has resulted in difficulty to select gears (especially reverse) the pedal was only doing any work when it was virtually embedded in the bulkhead.

Knowing this, I have stripped everything out in order to replace the clutch plate; only to find that it looks to be ok and is measuring around 7.3mm thick. its a 180mm dia plate and the engine is a total bitsa modded 1275 in a 1990 RSP.

So!; what's the consensus? have I gone in the wrong direction here? from what I can ascertain; there looks to be more than enough meat left on it.

additional info - I did try adjusting the throw by adjusting the locknut by a flat before I went full scope.

 

any advice gratefully received.

So Verto?

 

the lock nuts only need setting once, it is self adjusting for wear.

 

so air in the system. Worn linkage parts. From pedal to release bearing. That’s 3 clevis pins and their yokes that can wear.

As Nick says, the problem is likely to be in the clutch release mechanism.

Thus it could be: Master Cylinder, Slave Cylinder, worn clutch arm clevis pins, worn clutch arm bottom ball, a damaged flexible hose; or even a combination of these.

Apart from the master cylinder, all the other parts are easy to change and not expensive, so you might just want to do a system rebuild including a new arm.

thanks chaps I'll look into these (with the benefit of hindsight- I probably shoulda posted here before I got the spanners out!! of course then, i would've missed the joy of getting THOSE bellhousing bolts out!!     )........

Nick- in (tardy) response- its the non-verto type

Ok. So not original. Then yes the same apply but yes you do need to adjust the arm return stop. And the slave has been changed to the type you can fit the return spring to?

You need to cut a small hole in the bulkhead for the pedal :) Just to add to the people saying hydraulics that happened to me: just a little bit of fluid seeps out somewhere, a little bit of air gets in, and you don't notice except the bite point moves down. If this is it you will probably see a drop in the level in the MC, and evidence of leakage depending on how clean your engine bay is.

...... depending on how clean your engine bay is.

My money would be on the release bearing. Strip it and have a look see

You must have it in bits already if measured the plate..
