Re: Clutch Pedal Problem on 1972
Hey, thanks for the extra degree.
It's my admittedly limited experience with these Z-bar linkages that
the amount of pedal travel between "at rest" to "jammed down against
the floorboards" is just a little more than enough to cover the range
from having the clutch fully engaged to clutch released far enough to
make a shift, or to put the thing in gear, without grinding the gears.
Anyway, it works for me and everyone else to rely on the pressure
plate, without the under dash assist spring, to control pedal return.
So my first thought about Joe's problem is that he needs to adust his
linkage tighter, so that the pressure plate could do that job. (By the
way, in a stock setup there should be a much lighter gauge spring
connected to the clutch fork, that holds the throwout bearing off the
pressure plate fingers or diaphragm when "at rest." This spring also
helps to hold the entire linkage taut, and it's supposed to prevent the
buzzing you mentioned.) But he mentioned that his pedal can be pulled
up that little bit more and that it will then stay there -- which I
take it to be that it is the assist spring that it holding it there.
All in all, Joe's description suggested the possibility of a binding in
the clutch mechanism, not a worn out assist spring. The fact that he
does not mention problems with gear grinding suggests that his linkage
is adjusted, at least well enough to do the job it's supposed to do.
