[Healeys] Clutch

[Michael Salter]

The DW release bearing looks to me to be an adaptation of what is used in
the TR6.
My experience with those has not been good. Back in the day we used to
replace lots of TR6 pressure plates because the bearing had tightened up
and then worn off the pressure plate fingers.
If you must modify the clutch operating system the go whole hog and fit a
concentric slave cylinder
Lots of work but bullet proof.
I fitted one to AHX12 about 18 years back after the Toyota 4 speed type
failed in Newfoundland.
