[DeTomaso] Follow up, with photos Re: Clutch woes in Asa's garage

[Asa Jay Laughton]

I really do appreciate everyone chiming in to try and help me adjust my 
clutch remotely.  I've done everything that has been suggested, but it 
still will not work.  The last thing I did today was buy a Napa UP-255 
cylinder kit to compare it to what I have.  The slave cylinder I have is 
definitely NOT stock.  However the bore size is the same and the kit 
part and present part only differ by .001", the kit part being .001 
larger diameter than the present part.  And it fits.

So I assembled the new piston to the slave cylinder.  Then I removed the 
lever arm and moved it one more notch toward the slave.  Now, with the 
set screw backed all the way out, I can freely position the lever arm so 
it is both free of the pressure plate fingers when closest to the slave 
and resting on the fingers when about an 1/8" away.  This is as close to 
the slave as I can possibly get the lever arm.

Then I installed the pushrod (adjusted for the shortest length possible) 
and the external return spring.  Without -any- fluid pressure and in 
fact with the bleed screw open, the internal spring on the slave pushes 
the lever arm against the fingers of the pressure plate.  The -only- way 
to get the throw out off the fingers is to manually push the piston back 
into the cylinder... oh but wait...... when bottomed out, I still 
-can't- get the throw out bearing off the fingers.  This would tell me 
the clutch lever arm is too close.  Why is there even a spring inside 
this slave?  It seems to be the cause of all my problems, pushing the 
piston out far enough to contact the throwout bearing against the fingers.

Okay, so I didn't take video, maybe I should be that's a much longer 
process.  Here are the photos, with lengthy explanations accompanying each.

Does anyone know what the thickness of a stock friction disc should be?
