Eric,


I used the Bentley manual when placing the slave cylinder through the flange
attached to the transmission.  It shows the slave cylinder with its bolt holes
behind the flange (in other words, it shows the slave cylinder as having been
put through the flange hole from the rear of the car).  

>>>>That is correct.

Based on several comments from listers, I have given up my thoughts that
this might simply be a system bleeding problem.  

>>>>Don't give up on that idea yet.  If you bleed the slave cylinder when it is
mounted it can hold a tiny bit of air in the part of the cylinder that is above
the bleed screw.  Unbolt the the slave cylinder and bleed it so that the bleed
screw is at the VERY top.  I think I did this by loosening the bottom bolt and
taking out the top bolt so I could turn it.  A small bit of air CAN make a
difference.

Several of you havementioned that the slave cylinder's bolt plate should sit in
front of the transmission flange.  

>>>>That is correct.

Others have mentioned an adjustable slave cylinder push rod that should solve
the problem.

>>>>TR6's don't come with them but I've seen one made that works like the ones
on earlier TRs.  You cut the rod off the slave rod and drill and tap hole in the
remaining U-shaped piece.  Use a long grade 8 bolt (I forget the length but
you'll have to go to a fastener store to get a long enough one, approx. 6-8
inchs) for the rod and bolt it to the U-shaped piece and you have an adjustable
slave rod.  You can also add a spring to keep the TOB from the clutch to add to
it's longevity and/or don't always sit with the clutch engaged at stop lights
(cause you're spinning the TOB).  Put it in neutral.


2) If the slave cylinder is attached with it's bolt plate in front of the
transmission flange, the push rod doesn't seem to want to meet up the clutch
throw lever.  Bentley's shows the slave cylinder bolt plate toward the rear of
the car, but Moss shows it toward the front.

>>>>The bolt plate goes between the engine and the tranny.


3) I don't seem to have any adjustment at the clutch pedal itself.  After
rebuilding the clutch master cylinder, I also know that there is no
adjustment at the pedal push rod that goes into the clutch master cylinder.

>>>>Clutches are basically non-adjustable.

4) All the manuals state in bold letters that the slave cylinder should be
attached to the clutch throw lever in the middle hole.  This I have done.

>>>>Middle hole is for TR6's.  I think Saloons use the top hole and the bottom
hole is for Stag's, but I could have those reversed.
