Clutch advice needed

Mikael, There was a recent discussion regarding clutch adjustment on the deTomaso list you should check out. Dan

Thanks Dan, read everything named clutch and slave in there.
My conclusions would be (please let me know if any of you disagree):

1. The rod in the slave does not affect the clutch free play, it only affects where the piston in the slave is. Unless of course the piston bottomed out when pedal is pushed, in that case adjusting the rod would have an effect. The rod (middle of eye to other end) should be 3,07-3,09"
2. The proper way to adjust is to remove return spring, have engine running, use hands to move arm until bearing is felt to touch pressure plate fingers. At that exact point the distance to the return stop bolt should be 0,102-0,106". Adjust stop bolt. Install spring again.

If 1. and 2. are true, that means that
a. TSB 10 page 9 instruction on how to adjust stop bolt is grossly misleading
b. When clutch is at rest, the arm should also rest against the stop bolt. When I bought the car, the previous owner had adjusted so there's a 0,1" gap at rest. I can't really blame him, that's what I would do if I had only TSB 10 and not this great Forum . Maybe that's why my slave cylinder failed, nothing but the piston to take the beating when the clutch pedal is released fast?

I hope this is right, I can't afford another clutch, or worse wearing down my syncros...

Sounds like you’ve got it adjusted correctly.

Well I finally got around to fixing this, car was getting new fuel pump, oil hose etc., so engine didn't run. Now, how do I feel "bearing is felt to touch pressure plate fingers"? There's a point after moving it a few miliimeter where resistance is suddenly much higher, is that it? Before that point, I could neither hear or feel any difference (engine running, spring detached).

If I'm doing it as just described, the end result is that the stop screw stops the arm returning 1-2mm from where the arm rests without the stop screw, so not a big difference. And I can get the car in Reverse when idling without problems. Good signs?

Just after I posted this, I looked in Pantera Technical Information, 16-02-03. There it says to discard the stop bolt and adjust the pushrod. Actually I think there's a word missing. It says in the text "The pedal free travel should be 1/4 to 7/16 inch, equivalent to 0.102 to 0.106 inch [?] of withdrawal lever clearance". And in point 5. it says "Adjust length of push rod to give 3/4 inch of free play and clutch pedal retaining locknut".

1/4 to 7/16 is equal to 0.25 to 0.44. And 3/4 is equal to 0.75.

Can somebody explain, I've now read 3 different methods in the official Pantera publication?

Can the pedal be adjusted at the master cylinder, and if yes, what is the right measure so it doesn't bottom out?
