[Healeys] hydraulic clutch question

[Alan Seigrist]

Steve -

Your throwout bearing should not be "riding" on the clutch when in the rest
position.  It should be just backed off slightly very similar to a disc pad
in the rest position on a disc brake.  If it's riding on the clutch housing
that will result in premature wear of the throwout bearing as well as the
driven plate and your flywheel.
