Technical Clutch pedal not working after clutch replacement.
I have tried so many combinations that now I'm not so sure.
You need to check this
Because if they do bend flat I can't see it being anything except the refitting of the flywheel
If it's fine, then it's almost certainly a compatabiliy error
Yeah, that step has got me doubting. I know the old friction plate sits flat on it, the new friction plates are the same size as the old one and I'm fairly sure they sit flat against the flywheel but have not looked for it specifically.
Yeah I will do that again and record it.
Cheers 
I did try and cross reference the original AP part numbers
Unfortunately I didn't get too far
The number on the drive plate is generic and is used in many different clutch kits. The numbers on the pressure plate didn’t come back with any hits for me

Does the old pressure plate fit with the old friction plate - presumably, yes.
Does the new pressure plate fit with the old friction plate?
If yes, compare new and old friction plates.
If no, you have an incompatible pressure plate.

Good morning everyone,
I have done more measurements and here is how the friction plates compare to each other and sit against the flywheel. I measured the step that was observed on the flywheel at 0.04 with my caliper. I gave it a few passes with the emery cloth. Some hairlines on the flywheel left by it.

The centre of the new friction plate looks higher then the old.
True, this is the Ridex one but the same thing happens with the Valeo and the transmech. The transmech is the one that most resembles the original.
I am also almost sure that if the original friction plate was not worn, it would also compress the spring diaphragm flat when torqued to spec and thus no clutch pedal travel.
If i am looking at the video of the old old clutch being refitted
The fingers don't compress
The release lever is at the correct angle to the bell housing
But there isn't enough movement and the pedal jams
And all the other clutchs fail at the tighten the tightening pressure plate stage
The only thing that's changed is the flywheel been off
If this is correct I suggest trying to see what happens if you tighten one of the new clutches to the flyweel off the car

Does both friction plates sit flat against the flywheel without the pressure plate?
Let have a recap
The clutch was working but worn out
The gearbox was taken off
The flywheel was taken off
The surface of the flywheel cleaned up with emery
A new clutch fitted but the fingers now get mashed down
The slave cylinder get smashed off
New slave fitted
The same happens with Ridex Valeo and the transmech clutches
Original AP worn out clutch refitted. The release arm is in the correct position but now the slave only has 5mm of travel before it jams instead of 15+ mm
It was working now doesn’t
I'd start by taking the flywheel off and fitting one of the new clutches on the bench.
By loosing the centre spacer and bolts. There not much it can be. On the bench it should be fairly obvious

Yes, they do .
No
One end is welded
The other has a spline that's different
Anyhow if you compare my video posted earlier and the original AP clutch fitted above you will see they are identical except the original posters jams after 5 mm of movement
