Alpine R8 GT Turbo Too?

Friction plate splines looked damaged to me, on the bottom 4-7 o'clock, if you say it's free on splines, I've no reason to doubt it.
But I did this to a friction plate rushing it, wasn't quite lined up and started to bolt it up, didn't feel right, pulled it back and went again, better that time , but I'd burred them, clutch wouldn't disengage property, so I couldn't get gears.
Stripped it , threw a new friction in.
Are there any corresponding marks on pressure fingers to back up your current conclusion?

The apparent spline damage is grease. The disc slides freely on the splines.

@Brigsy was spot on. I reassembled the motor/trans and slowly depressed the clutch until the disc turned freely. Then I depressed a little more and measured about 0.25 mm gap from flywheel to disc and disc to pressure plate. Any more pedal movement caused the disc hub to start rubbing on the pressure plate fingers. So the range of clutch pedal movement between inital release and onset of dragging is too small to be practical. My thought now is to remove the disc (again) and trim off some of the shoulder on the disc hub.

Good to hear you have got to the bottom of it. I guess its down to different manufacturer of pressure plate and clutch plate.

I would definitely trim/machine the centre down until it works.

Well, I got the new clutch setup working. The problem was I had installed the clutch disc backwards. I looked at my Haynes manual at least twice and still got the orientation backwards. My appologies to all who tried to help solve my problem.

The good news is the new setup is working fine. The new clutch "bites" a little harder than the old one but it's OK. And, the clutch didn't slip with boost increased to 6 psi.

That would do it, right enough.....

Shit happens, we've all dropped the ball.
Glad you've sorted it.
