Dears,
buyed a new 9.5 clutch for 1 s 2.8 '69.
when applied to flywheel plate gain a play is correct ? is excessive?
Hi Fred, if you think about it, the item your are holding, the fingers are trapped in a groove, when you depress the clutch pedal the fingers are depressed and the effective diametre of the ends of the fingers will decrease so it needs that free play I believe.
Thank’you Robin,
A clutch cover already detroyed after 800 kms only, my doubt is that excessive play causing
bad work between clutch cover plate and release bearing, 
on left clutch cover on rotation at 800 rpm , he can go to 2000/3000 between gear change.
obviusly release bearing on right ( is like carbon ring ).
