Triumph Repair: 1976 Triumph Spitfire Clutch, clutch pedal, mechanical linkage

Question
My specific question is in regards to the clutch disingagment from slave cylinder.

How far should the slave piston move to disengage the clutch? My problem is that the clutch does not disengage when I push the clutch pedal and it appears that the clutch piston is currently moving about 3/4 of an inch. Also -when observing the slave piston while pushing the clutch pedal in the piston does not immediatly move.

Note: I have already bled all of the air from the system. Air in the system is not an issue.
Thanks

Answer
Wayne,

I don't have the exact number but 3/4" sound about right for the slave cylinder throw.

Keep in mind that you can adjust the clutch slave by loosening the pinch bolt on the holder and moving the slave cylinder forward.

As to free play in the clutch operation, the first thing to do is examine all the mechanical linkage for wear.  It's common to have either the pedal bushing or the top end of pedal to push rod holes wear out.  If that's the case, you'll lose motion.

Until you actually see immediate movement when pushing the clutch pedal then you can't totally rule out air trapped in the system.


Cheers,

Jim
