I have a strange problem with a XK140 OTS, (original fourspeed, no OD).
The clutch is a Borg & Beck, I installed it all new two years ago and was working perfect until now.
There was some noise from the clutch when the clutch pedal was pressed down and the clutch was not released until the pedal was close to the floor and the car was hard to shift.
I adjusted the clutch links outside the belly house and the pedal feeling was now ok, But when I started the engine, it now was impossible to shift into any gear at all.
I tried to turn the engine over with just the starter motor, now everything seemed to work ok, I was able to shift and the clutch released ok.
I started the engine again, it was still impossible to shift and the clutch did not release.
I suspected a half broken tapered pin or a crack in the clutch fork, so I removed the gearbox, but found these ok.
I removed the whole clutch, still looked like new.
Then i measured the clutch plate as in the photo, with a ruler over the plate and against the six bolt holes in the clutch cover.
At four holes i got 3.3 - 3.7 mm, (0,13 -0.15) but in one direction it was 3,15 mm (0.125) on the bolt hole at one side and 4,2 mm (0.165) at the opposite side, Could this be the reason why the clutch dont release when engine running? Or do you have any other ideas?
Hope i made myself understood.
Thanks in advance
