[DeTomaso] Long Week with #4268

[Mad Dog Antenucci]

Lessons Learned the Hard way include but are not limited to;
   
  On replacement of the clutch master... make sure the clutch rod is not binding-up due to misalignment of the master through the wall.  Clutch engagement &disengagement should be smooth....corrected the binding-clutch-rod problem by just re-alignment and re-bolting master.

  Mike,
It is actually the push rod that comes out of the back of the clutch master and not the slave. The first time it broke was with a different clutch, years ago. I have seen that rod bent while doing one of my numerous clutch master replacements/rebuilds. I drive the car hard and I think you are right. I think what is stopping the movement of my clutch pedal is the piston in the master going to the end of it's bore? So, I'm thinking if I beef up the rod, that will mean the end of that problem? I could probably make a stop for the clutch pedal but I want to make sure I get full disengagement of the clutch. 
Thanks,
Art

On the test drive, I break the push rod that goes from the back of the clutch master to the clutch linkage. It used to be about two steps forward and one back, now it is like three back and none forward! What's up with that? I think this is the second time in ten years I have broken the clutch master push rod, I'm thinking I need to beef it up, any ideas?



>>>I am presuming that you are breaking the rod from the back of the clutch SLAVE, no?

Something is definitely wrong here. Within a few days, you break the clutch arm, and now with a new arm, you break the rod that pushes on the arm?

Sounds to me like your clutch is misadjusted somehow? You are actuating the clutch until it reaches its mechanical limit, but you still have more pedal available, so you push further, which generates the immovable object/irresistable force scenario that results in parts breakage?

That's the only think I can think of. I have never heard of a clutch slave pushrod OR the clutch linkage arm ever breaking before....
