[Healeys] clutch hydraulics question

[David Nock]

Your clutch hydraulic hose has colapsed on the inside and the fluid is slow to return to the master after releasing the clutch pedal. As long as there is no slippage after you get moving you should not have a problem driving the car to the shop

Hi
First time on this forum and haven't got the foggiest idea what I'm doing.

I've taken out my Healey for the first time in two years. My problem is the clutch is not functioning properly. I can let it out fully and, with pause, the car will move forward or backward. seems the gas pedal is taking over the clutch's function. Can I drive it to a garage or should I have it towed ?

  There is no suction from the hydraulic system. The pressure plate springs push the rod back in AS the clutch peddle is returned. Actually if you push in the peddle with the rod disconnected then release the peddle additional fluid will be drawn in from the reservoir and another push on the peddle and the rod will pop all the way out.  

  Actually there is a small spring inside the slave cylinder positioned to lightly push the rod outward for which there is no apparent reason. I discovered this when I tagged out the carbon throw out bearing in berry little miles. Apparently my clutch linkage had very little resistance and this spring was maintaining contact of the bearing. Since there was no reason for the spring, I took it out. Everything has worked fine for more than 25K miles

    I think the throw out bearing pushes back on fulcrum arm and that pushes piston forward. I need to lengthen the fulcrum point on my smitty 5 speed system so the clutch engages higher up. Some day I will.

      Listers,

      If the clutch lever arm is disconnected from the slave cylinder push rod 
      and the clutch pedal is pressed to the floor, the push rod is pushed to 
      towards the rear of the car.  When the clutch pedal is released should 
      the suction created in the hydraulic system pull the slave cylinder 
      piston back in?  Or does the system rely on just the pressure plate 
      springs to move the release bearing/lever arm/rod/piston back?

      Cheers,
