[Healeys] Throw out bearing

[michael.salter at gmail.com]

Based upon my experience with the TR6 clutch, which uses that system, I would be reluctant to make the change. They have a habit of wearing away the "fingers" of the clutch diaphragm.

I have found that the most common cause of carbon release bearing failure is a lengthened slave cylinder push rod which causes the bearing to be in continuious heavy contact with the pressure plate "platen" at all times. Furthermore the pressure rises as the clutch dics wears which exuberates (my $10 word of the day) the situation. 

There MUST ALWAYS be free play at the clutch slave cylinder push rod when the clutch pedal is not depressed.

Just sayin'

Denis Welch has them, too, but I'm too lazy to look it up for you ;)


Note you have to remove the metal 'platen' on the clutch cover; for some reason I'm not totally comfortable with that mod (but no personal experience).


Cheers,


Bob

After pulling the engine and transmission to address the oil in the coolant problem, I see that the throw out bearing is probably 75% worn while the clutch disk is maybe 25% worn. Short of the Toyota transplant, has anyone come up with a modification to replace the carbon disk throw out bearing with a modern concentric bearing?
