Replaced the ‘‘hydrostatic’’ clutch slave cylinder today with the
older/newer style (from Terry’s) along with the flexible hose.
Also installed the spring and the little tab that holds it to the
bellhousing.
Results were not what I expected. The ‘‘in/out’’ in the last half-
inch of clutch has been replaced with more travel, but down at the
bottom of the clutch travel. It also takes very little effort to
depress the clutch. It was very stiff before. I would estimate
that the pedal will move 2’’ before engaging the clutch, and then
another 2’’ to release it completely.
I believe that I have bled the system thoroughly, and I am nearly
maxed out on the length of the adjusting rod.
AND this did not cure the clutch slippage. But what it did change
was to make it occur when the engine has thoroughly warmed up.
Before, it was happening all the time.
At this point, I plan to see if a longer adjusting rod is available
for the non-hydrostatic setup to see if I can get rid of the slop
in the pedal.
Not sure about the slipping clutch. But judging from the foul
stuff that came out during bleeding, I am thinking that the master
cylinder cannot be in very good shape and may not be releasing
completely.
Any other thoughts or ideas?

If your pushrod is about 2.25", it is the hydrostatic one. The
non-hydrostatic is 4.25".
With the slave piston all the way pushed in, you should have
only a bit of play in the fork before it hits the clutch plate. Thus
as soon as you hit the clutch pedal, it starts to disengage.
If you have clutch slippage while having a lot of free play in the
pushrod, you have other problems. Like a worn clutch or a
diaphragm with a few broken fingers… Once the throw-out
bearing comes free of the clutch, none of the hydraulics plays
any role any more.

I like hot rods, really I do. Jaguars, Corvettes, 55 Chevrolets and others
can serve as a good foundation for tastefully and effectively modified cars.
Here’s one I had not considered.
