[Healeys] clutch slave cylinder

[David Nock BCS]

Either the wrong combination of clutch cover and throw out bearing. Or the push rod on the slave cylinder is to long

Gents,

 

About 15K miles ago I replaced the clutch (1960 BT7) and put in a new throw out bearing.  Recently I heard the dreaded metal-on-metal sound when depressing the clutch peddle.  Upon removing the trans, I found the throw out bearing completely worn down to the steel casting – hence the metal-on-metal sound.  On reassembly, I noted that the clutch slave cylinder put constant thrust on the push rod keeping the bearing in contact with the pressure plate release arms.  Obviously this is what caused the throw out bearing to ware out so fast.  I replaced the master cylinder and blead the system extensively – absolutely no air in the system.  Yet the slave cylinder continues to press the throw out bearing into the pressure plate.  Any ideas as to why this is happening????
