Hi, Eric. As a former sufferer of clutch problems, I can try my best to
help.
1. TR6's don't have an adjustable slave rod - the bean-counters got to
that. You can try to find (or buy) an adjustable one for a TR3A (did the
TR4's have them also? I don't know just when they disappeared). This may
provide some optional adjustment.
2. The slave plate bolts up at the rear. Remember - Bentley is a
reprint of the Factory manual, while Moss is a catalogue, so the latter
likely just switched places in the interest of visibility.
3. That's right - there is no adjustment at the Master end of things.
One question - do you have a lot of slop/wear at the master rod mount points
on your pedal arms (true for both brake and clutch)? These should be
lubricated lightly on a regular basis; over the years, the metal-on-metal
enlarges the holes, to where you may be losing travel.
4. Someone on the list months before said that the TR6 uses the middle,
while the Stag used one other and a third model (I forget which) used the
other. Again, not much difference - a few millimetres of travel, but not a
cure.
One trick that can be used is to insert oversize washers or even nuts
between the slave and the tranny flange to 'space' the slave closer to the
cross-shaft mount. This must be done so as not to keep the t/o bearing in
constant contact with the pressure plate - or else!
One final trick often used is to bend back the stop tab (striker plate -
call it what you will) on the back of the clutch pedal arm, to allow a
little more foot travel. Again, perhaps a temporary measure, but may buy
time.
How about the age/miles on the clutch plates? I had a bad B&B pressure
plate, and I currently have a Sachs (from a Volvo) plate in my TR6 (similar
to the TRF 'magic' clutch) - wish I'd done it years ago!

Subject: Slave Cylinder placement (was: tr6 clutch low grab)
All right. I apologize for not understanding, but after looking at
my
equipment and my Bentley's, Haynes & Moss catalog, I have further
questions.
*In the interest of our understanding, let me list some definitions
of
descriptions I will probably make up in my explanations:*
*Transmission flange* - the slave cylinder attachment point that
bolts up to
the bell housing.
*Slave cylinder bolt plate* - part of the slave cylinder housing
through
which the bolts pass through to bolt the slave cylinder to the
transmission
flange.
*Now on to the problem:*
I have a 1976 TR6 that, after rebuilding the clutch hydraulic
system, has
very low grab on the peddle as well as gear scratch (especially
going into
reverse - well grinding when going into reverse).
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).
However,
the Moss catalog seems to show the reverse of this - with the bolt
plate for
the slave cylinder sitting in front of the transmission flange.
Based on several comments from listers, I have given up my thoughts
that
this might simply be a system bleeding problem. Several of you have
mentioned that the slave cylinder's bolt plate should sit in front
of the
transmission flange. Others have mentioned an adjustable slave
cylinder
push rod that should solve the problem.
My questions are a few fold:
1) I don't seem to have an adjustable slave cylinder push rod. At
least I
can't find where I would adjust it. When I had the slave cylinder
apart, I
cannot remember any adjustment points.
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.
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.
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.
Could this be a problem?
I thank any and all of you for considering what this problem might
be.
