[Healeys] Throw out bearing

[Oudesluys]

There must be some way to adjust. Often the rod can be 
lengthened/shortened by adjusting a nut, the slave cylinder perhaps can 
be moved forwards/backwards, shimming etc. I presume the return spring 
in the slave cylinder is strong enough to push back the piston.
Excessive wear on the clutch cover can be caused when the bearing is 
just touching the fingers, but not enough to spin the bearing at the 
same speed, and/or by a foot resting lightly on the clutch pedal.
With the clutch pedal released a clutch roller/ball bearing should not spin.
