Joe---I can't think of any reason why just replacing the transmission
would affect the "crispness" in clutch takeup, short of the gear ratios
being different. Altho you are using the same clutch as before, I
suspect the answer lies here. Any chance you got a foreign substance on
the clutch disc, pressure plate, or flywheel while all of these were
apart?
So far as using the top hole in the clutch operating arm, it would
operate at a different angle, as you noted. The long term penalty for
this could be scoring of the SC bore, due to a side load placed on the
piston. A small price to pay for complete disengagement?
I've never seen it written as to why there are three holes in this arm.
I don't think earlier TR models ever used the other two. Just as the top
hole will give a somewhat longer stroke to disengage the clutch, (with
more leg effort), the bottom hole will take less effort to use the
clutch. Again, only the center hole gives the pushrod a straight shot at
the operating arm.

Hi,What's wrong with using the top hole in the clutch actuating lever? I
see that using this hole would result in a slight change in the angle of
the rod in relation to the slave cylinder, but since this is a hydraulic
rather than mechanical link, why would this be a problem? Why are there
three holes anyway? I recently replaced my transmission. I kept the
clutch components as they had less than 5000 miles (koyo bearing, Sachs
pressure/clutch plate from BPNW). I had no problems whatsoever with this
setup with the old transmission. Everything went back together fine, but
I have a hard time engaging reverse, sometimes first, and have a tough
time downshifting from fourth to third without grinding the gears.
Placing the rod in the top hole fixes the problem. The clutch master and
slave are relatively new. Also, with the previous transmission, I had a
very "crisp" engagement of the clutch. (I could easily spin the rear
wheels, and "chirp" the tires between 1st and 2nd...s! ometimes between
2nd and 3d) I know this is juvenile but... Now, I cannot break traction
at all. It's not like the clutch is really slipping much, rather it just
doesn't seem to be a "crisp" engagement. Whats up with this?Joe Davis
