So, I contacted RAM clutches awhile back about my ram 78100 that was really difficult to work back and forth by hand. I was told it might be cold or need worked back and forth to make it better. So I did that, and it seemed to be better when heated up to room temp (garage temps are about 40°). I installed the bearing finally today, and now, after having bled the system, the unit is fully extended and won't retract. The pedal is hard as a rock and feels like a brake hydraulic system. It's as if the unit is being held up somehow. I took it off the transmission bearing sleeve to make sure that wasn't it. No change. Still a hard pedal with no retraction. For giggles I opened the remote bleeder and manually retracted the bearing assembly, then closed the bleeder. I tried the pedal again, it went to the floor first pump, but then the pedal got hard again and the bearing fully extended. Any ideas? I swapped in a 3/4" master cylinder, the lines go hard line to a female-female inverted flare to the stainless flex line to the 78100. And on the other side of the bearing, the remote bleed kit.

Thats a problem in the master cylinder. The pushrod is adjusted wrong, or the piston is sticky. If it retracts when you open the bleeder, the slave is fine.

Really good to know. I'll dick with the master tonight.

This is with a pressure plate pushing back on it, right? If theres nothing pushing back, it won't retract by itself.

That's what I'm just now finding out. All of these tests I did were performed with the trans out of the car (I wanted to see how action I was getting!)

First lesson of hydraulic clutches- never step on the pedal with the trans out.

If you didn't blow the guts all over the floor it should be ok.
