Aurelia Clutch

[lancialib]

I am trying to help someone with a B24 Spyder who has a bad clutch judder problem. It has the Lancia clutch with the aluminium cover holding the springs as fitted up to the end of the 4th Series B20.

The judder is only on take-up from rest, but otherwise everything is fine.

Drive train is in balance; centre propshaft bearing correct, new spiders, clutch release bearing & fork motion is good, new clutch springs etc.
Changing gear on the move is fine. No vibration in motion.

He is ordering a new driven plate to see if it is this item.

Any ideas very welcome.

Thanks from Paul Mayo

Did you check the flyweel

Thanks, I believe so, not my car nor very close to me. I think it must be the friction plate. Another one has been ordered.

Based on the symptoms you described, the friction plate is the most obvious answer

In general yes, but you have keep in mind that you have two part to transmit the torque.

And if the flywheel is worn you have also an influence.( run-out deviation )
Should be measured by dial gauge to be save.

Thanks to Ed Levin and Racing. When I hear of the solution I shall post it. Your comments are being passed on.
