[snip] But the key is PROPERLY adjusted. That dead area in the clutch
pedal or travel BEFORE you feel the resistance of the throw-out
bearing contacting the pressure plate (typically 1/2 to 3/4 of an
inch, sometimes more depending on the vehicle, at the pedal) is there
for a reason. [more snipping] That dead space or "free travel" is
to provide a clearance for the throw-out bearing so that it DOES NOT
contact the pressure plate, and continue to rotate while the clutch
itself is engaged (pedal at rest).

Hi Barry - Yes, I agree with you that a "properly" operating TO bearing should
not contact the pressure plate. That's why I suggested the theory in the first
place. If the lister's clutch is NOT set up properly, the TO bearing could be
improperly contacting the PP all the time. And, no, I didn't take your comments
as a flame - just more info. on an interesting topic. :^) Cheers and best
regards,
