    I'm not exactly sure what the deal is. The clutch, pressure plate and flywheel only have about 1000 miles on them and were working fine when removed from the previous truck. When I let the clutch out it barely starts to move about 2" from the top of the pedal. The adjustment rod is basically adjusted all the way out. With the pedal at the top, my adj. rod is barely still in the cup of the shift fork when the pedal is at the top either.
    Any ideas

    As I thought, the dumbass at NAPA didn't know what he was talking about. He told me I needed the longer throwout bearing when I really needed the short one /forums/images/graemlins/angryfire.gif
    Took about 3 hours by myself to R&R the tranny/tcase combo. Put a motorcycle lift jack under the crossmember and a floor jack under the trans and pushed it back far enough to get the bearing out. I spent 20 minutes looking for the straps to hold the rear ujoint in. I finally found them right where I left them........screwed into the yoke on the axle so I wouldn't lose them /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif

    No. Pulled it out of one truck and put it in mine. Never unbolted clutch..at least I didn't.

    Dan, any chance you took off the clutch assembly when you pulled the motor????

    Re: Clutch adjusting problem???

    I understood that part, however the clutch disc has to go on with one side specifically meant to face the flywheel and the other side facing the pressure plate. The disc is not symmetrical...so it can be installed backwards. There should be some marking saying which side is which.

    Re: Clutch adjusting problem???

    The motor I bought still had the clutch, pressure plate and flywheel still attached to it. It was never taken off the motor from the time it came out of dan's truck to the time I put it in mine. He said he never had any problems at all. I'm just trying to figure out what else it could be. I really don't want to pull this thing out if you know what I mean /forums/images/graemlins/ignore.gif

    That eliminates that then... /forums/images/graemlins/ignore.gif

    Throwout bearing and clutch fork would be next up. Could the fork have come off the ball and be pivoting on something else? Does it make any noise while idling in nuetral?

    Is it possible the linkage went back together wrong?

    Re: Clutch adjusting problem???

    I'm thinking about a few other things now.
    I just called Dan and he mentioned something about there being 3 possible clutch forks: manual, hydraulic and something else. I had a 3 speed amnual in there before and I wonder if I could have used that fork instead??

    The other thing I'm thinking about is the throwout bearing. I went to NAPA to get a new one because the old one was still on Dan's 4 speed. The parts guy said it was the long bearing and not the short one. I have the ever famous Borg & Beck clutch.
    Any ideas/hints where to look first???

    Re: Clutch adjusting problem???

    I'm having a similar problem with mine. On mine, the clutch won't even come up on it's own. It appears to be that the fork has slipped off the pivot ball, so you might look into that.

    Yeah, it's a new spring as a matter of fact. The springs on the pedals are also in good shape. Going to drop the tranny tomorrow and adjust the fork and see if it's come off the linkage.

    Re: Clutch adjusting problem???

    My problem is the total opposite. Mine is a total pain in the ass...won't release all the way every time. Can't wait to ditch this setup....it's sooo frickin stupid.

    Just shorten the length of the rod from the Z bar to the fork and see if it moves the friction point.

    Re: Clutch adjusting problem???

    I think I may know what the problem is, if I have this thought out right. If I have a long throwout bearing then when I release the clutch it seems like the clutch fork needs to release more and the longer bearing may be holding it up from doing that. I really hate to drop that 200Lb thing again dammit!! Not sure if a bearing that is maybe an ince shorter will take care of that but I find out sometime soon..I hope

    Yeah, I know. I meant just the tranny. I think I still have scars on my chest and arms from last time /forums/images/graemlins/ignore.gif

    So how do you know which bearing you use? Could this be why my clutch doesn't release correctly unless I adjust nearly all of the free play out of it?
