    Ok, I put a new clutch assembly (Pilot bearing, throw-out bearing, 9.250 clutch, plessure plate assembly, clutch fork & Clutch fork spring) in the 1959 cj5 with a 134f-head and t-90 tranny. After about 200 miles the throw-out bearing died. I pulled the bell houseing and trany assembly from the motor this past weekend and replaced the throw-out bearing. When I re assembled it the clutch would not disengage no matter how much I adjusted the clutch cable? Any ideas what to do?

    The T.O. bearing prolly died b/c it was spinning full time. Gotta back that puppy back so it only spins when the clutch is depressed. Just FYI.

    Are you certain that the bearing was the same size? Maybe it died b/c of a bad fork/spring? Just some ideas. If you remove the adjuster cable, can you move the fork back and forth? Lotsa movement? You should be able to hear the bearing hit the p.plate and about half of the fork travel (that's my V6-only experience talkin' though :oops: ).

    If you haven't torn into it yet, try starting it in 1st gear (low range) and drive it around awhile. See if something loosens up. I'm actually having the same prob with my newly installed clutch on my V6.

    Hey I just noticed that you're in Carrollton. I'm just up the road in Portage Co. Feel free to ask if you need a hand on anything as I'm off work this month. :beer:

    Clutch disc installed properly? Thought I read where if the disc is in and facing the wrong way, clutch won't disengage. Or was that in a crazy dream I had? Anyone else?

    Actually, having the disc in backward can cause two things: Bad clutch chatter, since the spring hub is backwards. The second is that the spring hub can ride on the flywheel bolts and never let the friction surface touch the flywheel.

    Are you sure the clutch fork is seated on the pivot ball Pottsy? Is that little spring still holding the T.O. bearing assembly in place on the bearing retainer of the tranny?

    Take the cover off the top of the bellhousing and you can see what is happening as you push the clutch in. That is how I adjusted mine when I replaced it, I could see exactly when the TO bearing disengaged the plate.

    Ok, I pulled it apart and (pressure plate off and all). Everything looked ok? The fork was in the proper place, the spring and throw out bearing was on correct. I even measured the old throw out bearing vs. the new one and they are the same. I measured the pressure plate against the old one and it's the same.... I then put everything back together and started adjusting the cable... It kind of works! I can ajust the cable where it turns free and disengages 100% when the clutch is pressed to the floor. But then it does not engage enough to move the jeep when the clutch is let out. I currently have it set where the clutch grabs and holds well but that isn't happening till the complete last part of the pedal movement. I think I need to adjust the cable just a little more, but it is starting to feel like the gears in the tranny are still trying to turn even when the clutch is pressed in it's current setting. I'm afraid I'll adjust it (Loosen the cable) more and the clutch will engage closer to the floor in the pedal movement but the gears will not completly stop turning in the tranny. Does this make sense? It's as if I push the clutch in while it's in gear and it disengages, I then shift it in to nuetral and the tranny starts to turn slowly... I have pulled this thing apart 3 time last weekend and I sure hope I don't have to do it a 4th time here real some... :shock:

    Everything may look right but you're definitely overlooking something. Bottom line is the clutch should be 100% engaged until you push on the pedal, the end result being the clutch release arm pushing on the throwout bearing and disenaging the clutch via the contact area on the pressure plate. I'd start with making sure the linkage is all good and on correctly. One possible trouble spot might be the clutch bellcrank has a wrong/right way to go on. On wrong and the travel won't be the same.

    If all the slack is out of the linkage wih the pedal out and you still don't have enough grab to move the Jeep, I'd look at the clutch disk being in backward. My 340 Duster was like that when I bought it, the PO had just done a clutch job prior to the sale. :rofl:

    If the disk is in backwards, the spring hub will ride on either the flywheel or the flywheel bolt heads before the lined surface can fully contact the friction surface of the flywheel. The springs on the disk will get eaten away in short order too, since that is what usually contacts the flywheel bolts!

    FWIW- You normally cannot see this problem with the tranny in the vehicle. The difference in clearance is so small, you normally can't spot it until the tranny is out. With it out of the Jeep, you can see the hub of the clutch disk, and compare it to another disk. The side with the hub raised up is the side that should be AWAY from the flywheel.

    Good Luck!

    Thanks fella's good info! I adjusted it last night and it seems to work well? The clutch grabs at about half way up on the pedal movement. But one thing does concern me. As the clutch is starting to engage and the jeep is starting to move, I hear a slight TICK-TICK-TICK-TICK till I let the pedal completly out! It's not really load but I notice it! Would this be a sign that the clutch disc maybe in back wards?

    I'm thinking about pulling it apart this saturday again. and verify that the disc is in correct? I'm still not clear on how to visually tell which side of the disc goes toward the fly wheel...

    Give me a brake here fella's, I'm a Carroll County Hill-billy Kid with a bunch of tools..... :D

    You missed what Steve wrote. The raised portion of the disc hub goes away from the flywheel. Sometimes the disc is marked flywheel side. Definitely can't go wrong there. ;)

    so do you think that slight TICk-TICK-Tick sound prior to clutch engagment should worry me enough to pull it apart or does that sound kind of normal?

    I won't say it's normal. But I will say mine makes noise too but the clutch works fine. New T/O bearing of course. No noise in mine when engaged, so I've let it be.

    I guess when the clutch disc has stamped on it "Towards Flywheel" then your should position the disc in that direction.... I found my problem... I had the clutch disc in backwards... Boy do I feel stupid... The worst thing about it is.. I screwed up my disc, which was new! I'm in search of a new 9.25 clutch disc in the north east ohio area today....

    I checked out your website Potsy. Nice work! You are a master craftmen with metal. I wish you lived next door. I don't have any suggestions beyond what others have offered but I sure you're on the way to resolving the problem.
