    ok so i finally got everything straightend out with the adaption (some of you may remember my last post). the noise is gone and all is well except that the clutch seems not to want to function. if you push the clutch pedal in and try to shift it the gears grind and if you force it it will pop into gear and even with the pedal depressed it will drive forward. it is if the clutch disk is not releasing from the flywheel. i have tried adjusting the linkage and cranked it down as tight is it will go to no avail. the puzzling thing is that this all worked before i fixed the adaption alignment problem, and now it wont. because the springs were broken on the old clutch disk i got a new centerforce one, but that is the only part of the clutch thats different, could this not be working with the rest of the clutch assembly?? thats about all i can think of. do you guys have any thoughts???

    i want my jeep back, the summers already started! must go fishing!! :( :mad: :mad:

    OK.. try not pushing the clutch all the way to the floor and then shift into gear. I had the same almost exact problem and it was i had too much throw on the fork.

    ok i tried to shift it into gear with various levels of pushing the pedal and it still would not go and grinded, my problem seems to be that i do not have enough throw on the fork, like the t/o bearing was not pushing the diaphram in enough. any other ideas??

    is it a hydrolic setup?? I tried to use a push type slave and it didnt work and that was with the t90 i had. I changed to a wilwood pull slave and it worked then. How much adjustment do you have on the fork?If you have too much slack then you lose that much in throw. I tightened the pushrod down just when it puts a little pressure on the fork, not too much or there will be constant pressure on the fork and things will wear out

    it is the stock mechanical clutch linkage, and i have tried adjusting it to the point where there is no slack in the system and the t/o bearing is riding on the forks and it still will not work. i am also sure that the disk is not in backwards, ill have to check on the springs hitting the flywheel bolts...keep your thoughts coming...

    What kind of clutch are you using?? I at first tried the centerforce pressure plate and disc, but went to stock items to try and figure out my problem. Not saying the Centerforce parts are bad, but i did read in places that sometimes they just dont work right adn alot of people do goto stock stuff. but that is just reading the internet writings, i cant say this is true. For my problem it was the thorw and none of the cetnerforce stuff. Possibly you are just experiencing a new disc and need to break it in. I put the jeep in gear against a tree and started it to get it to "seat" It seemed to work for me and other people have done the same thing. Can you start it in gear??

    I had a similar problem after I installed my Centerforce clutch, it's kind of embarassing but I had mistakenly installed the T.O. bearing backwards. You might want to check that out. Also, IIRC Centerforce clutches require their own T.O. bearing but I might be up in the night on that part.

    its a stock style clutch-a rebuild from napa- that i originally had a napa disk on, but since i broke that disk when i was pricing out a new one i found that the centerforce was not much more so i decided to upgrade. so it has an original clutch with a centerforce disk.

    i can start it in gear, i will try putting it against a tree and seating the disk, maybe that is it since the disk is new while the rest of the clutch and flywheel is not.

    Is it a Centerforce I, II, or DF??

    One of those, II or DF, have weights on the fingers that may cause an interference problem... Dan, isn't that what you saw at some point??

    Here's a pic of the different Centerforce clutch discs...

    ...depending on how those weights line up with your TO bearing, it might cause the problem.
    I run a Centerforce I with my T18... no engagement/disengagement issues... but a local shop did the install 10 years ago, so I can't say exactly what was done.

    The fingers seemed to be hitting the disc hub in the center. i actually took the weights off, they really are not good for the jeep since they only work with high RPMs, jeeps dont really use that to their advantage.
