New Clutch won't disengage - Very Frustrating

    Thanks for checking out my problem.

    I have a 74 CJ5, 304 T150 that had a new Luk clutch kit installed in it by a mechanic. After the install I drove it home with no clutch problems. I started having motor problems and ended up pulling the engine and putting another 304 in. When I pulled the engine out, I saw that the clutch fork has slipped out of the groove on the throwout bearing and was riding on the back of the bearing. I fixed the clutch, got a new throwout bearing (same one that was in it), and installed the different engine. My problem is that now the clutch will not disengage the transmission at all. I took a look through the inspection cover while working the pedal and there was no change in separation between the PP and flywheel. I adjusted the linkage out so that the throwout would travel further but still no disengaging. The pedal has proper "feel" and springs right back once you let off. Here are some links to pictures of the linkage. I don't know if I just need to extend the linkage even further, or for some reason maybe the PP is stuck to the flywheel (Not likely, but I'm brainstorming). I'd obviously rather not pull it apart again. Any input is very appreciated. It has been one thing after the other with the Jeep (I know, its a Jeep thing and this how it is).

    Here are some pics

    Are you sure the clutch disk in in correctly? If it's in backward it will let the buffer springs ride aganst the flywheel and it will not disengage. Even if it does it'll make a bad noise and eat up the springs and flywheel bolt heads.

    The clutch plate is flush against the flywheel so I believe it is installed correctly

    If the clutch rod was the correct length before you pulled the engine then it should still be the correct length. Try extending the clutch rod more.
    The only other thing I can think of is the clutch disk backward.
    The pressure plate is going to push it up against the flywheel whether it is installed correctly or backward.

    I am going to conclude that the disk is backwards since I adjusted the linkage out a lot more than it was with no results. I'll drop the trans and see whats the deal is.

    Thanks for the replies. A lot of support is needed with these jeeps (Especially when you don't read instructions)

    Mmm. T-150? Really? The original transmission in a '74 with a 304 is a T-15, not a T-150. Not the same. The only way a '74 would have a T-150 is if someone swapped it in. Make sure you have the right parts to match your transmission.

    I'll double check the transmission, that could complicate things

    The other thing that comes to mind is your throwout bearing may be too short. Maybe it worked previously since the fork was behind the groove; maybe the mechanic couldn't get it to operate in the groove so he put the fork behind the groove? Now in the groove there's not enough length to push the bearing in.

    As Tim said, research that tranny. Comapre TO bearings for the T15 and the T150, see if they are different...

    A T15 tranny will have the number 13 07 xxxx on the case.

    A T150 will have something like 2603983 or 2603347 on the drivers side

    I dropped the trans tonight and it was indeed that the clutch disk was backwards. I appreciate the help in correctly diagnosing this prob. I noticed I need to get a new trans mount so I'll be ordering one of those and then putting it back together. All help is very much appreciated.

    Thanks

    Brad
