    Damn-it....Runs fine completly redone wont shift ..I tried to pull it in low range ,,bump the starter while in gear..2lb sledge hammer wont come loose...This is one I have been working on for awhile ..I had a block under the clutch pedal so the plate wouldnt stick to the flywheel which has happened to me in the past...any ideas..heres a couple of pictures I took to show exactly what the problem is...this ran before I parked it 6 months ago..This is in a 1946 1/2 CJ2A with a L-head ..t-90

    Picture # 9 clutch out
    Picture # 10 clutch in
    Picture # 11 clutch out..

    this is gonna sound really stupid.........
    try starting it against a tree or other solid object
    the engine will turn, but the drivetrain won't
    bump starting should do it

    I believe so....I cna put it in 2nd gear and start it right up ..wont disingage..I can push the clutch in and of course it just goes around..the springs wont come back like the disc is froze to the flywheel and the pressure plate...I take it out of gear and it still wont come back..???

    if all was working beforehand....
    no repairs made to clutch or trans...
    bumping it up against solid object in gear
    maybe 2nd or 3rd
    you don't want to pop it in first, it's weaker
    got to try and slip the disc/clutch somehow...
    only thing I can think of without disassembling..

    Sounds too obvious, but maybe it's just worn out? The pivots for the Borg&Beck style fingers eventually wear and maybe they jam? As I understand this, it's as if the pedal were depressed all the time - the fingers on the pressure plate are locked in their pushed-in position. Yes?

    Maybe try turning the engine and tapping on each finger with a long drift? Maybe it will sproing back. I would not have much confidence in that clutch cover though...

    i am confused,not sure i understand,but this is the way i take it,the disc is stuck to the flywheel,clutch pedel works fine and the preassure plate does too,if this is what has happened you want to get in the higest gear you have 3rd,high range if you can do it,ride it around with the clutch pedal in it will free up

    I'd say the levers on the pp are stuck, as mentioned. Maybe you can carefully spray some penetrant on the fingers and hope it doesn't get on the disc?

    if its flat down there in NC you may have to hook to something,like a tree and try it in H-4,3rd gear,its absoultly amazing how stuck these things can get,I had one in a comando i thought would never release but it did eventualy,almost gave up on that one

    This works well...and does not sounds stupid to me. When I first got my 3A it was stuck too...I used this exact method, and also drove it around with the clutch pedal to the floor and hit/let off the gas many times...it eventually let go. The tree method works best, I've done it a few times with different jeeps.

    Ok, I guess I'm confused. Is the pp stuck in the released position? I thought you said you can start it in gear and nothing happens. Or is the disc stuck and you can't get it to release?

    It will start in gear and then hang on...the pp is stuck in the open position..

    Ok, that's what I thought with the pp. But what do you mean by "then hang on"? All the tricks you've been trying won't do anything to the pp if it's released.

    It takes off..If I push the clutch in all it does is ride on the springs..I can take a pry bar pull the fingers towards me..If I put the pry bar in between the throw out bearing and the fingers they only go in about a 1/4 inch...I can oput it in gear turn the key to start and it is in gear ..takes off..If I take it out of gear it willl run ..If I try to shift while running it grinds the bearing just hits the fingers on the pp

    Thanks for clearing that up. With the pp released as you left it the disc must have still been close enough to still get stuck to the flywheel or pp. I wonder if it's stuck to the pp and frozen on the splines too, therefore holding the pp where it's at?
