A year ago I posted this problem and since then there has been no time
to address it. little has changed but I have been able to dedicate some
time to it this past week.

Once the car was back running a test drive showed the problem was still
there and possibly worse,  In fact besides gear grinding if I attempted 
reverse while the car was running, the forward gears where getting
difficult
--pedal to the floor and tough to get in gear.  

I checked all the pinning and no excessive wear or elongation.
I blend the lines and do believe there was some air in it.  Once 
completed, the clutch will now NOT dis engage so with the engine 
running it will not go into gear and reverse is a still a grinder.

I checked the throw on the slave rod and measured 14mm or 0.551 inches
and per Vance ". .  at a minimum, you need 0.625". . . " in a March '04
email.

My questions:  Could the master cly. be bad?  There is not leaking 
of fluid but perhaps the seals are gone and fluid is being forced 
past them of the travel is not as effective.  The slave is probably
three years old.  

Second, The slave mounting is correct and assuming the master is okay,
is there any issue with adding washer between the slave flanges and 
mounting bracket? The goal is to make the 0.551 more effective in 
dis-engaging the clutch.

___________________________________________________________

I have been a TR6 ('76) owner for many years but my memory of past 
problem fixes is failing me.  I have had this problem before 
but not sure of the fix.

In order to get the car in reverse, I need to turn off the engine else
the gears in the transmission are still spinning and it is a 
gear grinder. 

Around 5 or 6 years ago, a new clutch and throw-out bearing were
installed (bearing pined as well).  Honestly I do not remember if 
this was the remedy before or not.  Car is not driven that much 
to need a new clutch.  But I do know the clutch pedal is to the 
floor and seems to not fully disengage the engine especially when 
it is HOT.
