Clutch problem

Hello all. After starting up my '86 CJ7 in gear with pedal fully depressed it tried to move on me. However, when I let the pedal out out just slightly the clutch disengaged. Letting the pedal out further engaged it again as normal and I could drive it. The pedal feels normal, not a lot of play. I checked the linkage and everything other than the boot going onto the transfer case looked ok. (the boot had come loose on one side so it just pushed it back in). I've adjusted linkages before but that's usually been when there too much play in the pedal and it won't disengage at all so I'm a little perplexed . I can fool around with the linkage but thought I'd see if anyone out there had a thought before I tore into it to much. Thanks!

Adjust your pedal to have 1" to 1 1/4" freeplay.
IF, your aare still using the OEM linkage and down rod. I will bey it is worn out, and the holes are egg shaped.
Check your bellcrank too.

Ok, I've adjusted the linkage back (toward the throw out lever) to where there is pretty much no play in the pedal and the clutch still will not disengage. I guess now I will have to start taking it a part. Do you think replacing the linkage will do any good or might I have an other problem. Btw, there was no warning this was going to happen. It shifting fine one day and the next nada (in case that gives any clues).

Bet you have broken springs inside the pressure plate.
Also check to be sure your linkage bellcrank ain't moving all around on it's mount.

You will have to R&R(remove/replace)the clutch assembly.
To do that. You must remove the transmission and transfer case.
THIS, is where a REAL, FSM is handy.

Lumpygrits, you're going to think I'm crazy because I think my Jeep is making me that way. But now, on a whim after doing nothing I get in start it up and everything is working. I'm shifting into all gears and its disengaging as it should. Had wife push depress the pedal and everything looks fine, I looked behind the boot and from what little I could see that all check out. So I dunno. Guess I'll drive it around a bit and see what happens. Thanks for your help maybe the threat pulling the tranny and transfer case scared it back to working.

Start'n to sound like a linkage issue for sure.
AGAIN, inspect the bellcrank and ALL pivot points for wear.

Hey, here's an update for the guys that tried to help me out with my clutch issue (Lumpygrits and seabass). I finally threw my hands up and took it to my mechanic. He had a hard time figuring it out too. Ended up pulling the Transmission twice after thinking he had it fixed. Turns out one of the metal tabs that sort of hold the springs in on the clutch disk had broken off and was causing all the havoc. Not sure how that would even happen (it was a new disk too so maybe defective?) Anyway no way I was going to be able to figure that out on my own or fix it myself. But thanks so much for your input. I'm sure I'll be asking for some more sooner or later.

A different mechanic that does some garage work on the side. He was replacing the Flywheel at the time so I had him to take care of the clutch while he was at it. I'm not sure how the pressure plate and the clutch disk interact but I don't think there is anything that would break or shear that tab off. And you'd have a hard time trying to break it off if you wanted to. I can't imagine dropping it would bust that off. Weird
