Allen,
On my Tiger II the clutch slave cylinder had an adjustable
length push rod. Could be that the fingers on your clutch
pressure plate are worn down and you need a longer push
rod to make up for the slop. Try adjusting the length by a
turn or two. If you truly have a heat problem then I would
assume that the fluid is expanding and you would tend to
release the clutch more, not less. If you have water in the
fluid then boiling will cause a soft clutch; however this
normally only happens at above 212 degrees. Are you
truly getting that hot? On my Tiger I have huge headers
that leave little room for the speedometer cable. The inside
of the cable (plastic) melted once. I solved this problem
with a 1/4" layer of fiberglass (woven kind for boat repairs)
and covered the fiberglass with several layers of aluminum
foil. Used hose clamps to secure the foil around the cable.
You could do a similar thing on your clutch slave cylinder.
If you have an old flexable hose going to the cylinder then
maby that is the problem as well.
I had a clutch cylinder split on the side when I installed
a Hays heavy duty clutch that took a huge effort to disengauge.
On my Tiger II 351C I use a mechnical linkage that
piviots at the regular Ford piviot ball near the rear of the
motor. Note that I also moved the firewall back 6" to
clear the motor and to allow the use of the mechnical
clutch linkage. Mechnical linkage does not fit a un-modified
Tiger.
