    So I have a new McCloud clutch and an aluminum flywheel installed on the new flatmotor. Problem is, my clutch won't disengage. The linkage is pushing the clutch arm all the way forward till it hits the tranny, and when I look in there, it appears that the pressure plate is off of the clutch disk; it's moving. There are three small bolts on the clutch prongs that look like they can be turned out, but I'm not sure if that'll move it enough, or if I can even adjust those. Any thoughts fellas??...trying to get the car moving down the road by the Round Up on Sat. Only picture I have is it sitting in the box. Doesn't really look much different peering through the inspection plate in my tranny. :)

    Smalls, do not try and adjust the finger bolts.. you will play hell ever getting them exactly right ( they have to be even , and are set by the cluth mfg..)
    The most likley cause of your problem is a mismatched fork and or throwout bearing.
    What trans/bellhousing are you running ?
    A little more info and maybe we can science this thing out for you..

    Yeah... I'm thinking throwout bearing too... I think (though could be wrong) that there are two different lengths. Maybe one of the old guys will speak up and set us straight.

    Throwout bearing is the same one from the old motor, not exactly sure what the PN is. I have a 1 3/8 " x 10.5 clutch disc, and 10" Long Pressure Plate (Red's Parts list)

    Pressure plate is moving you say so that it moves away from the clutch plate thats all good clutch plate is just stuck to the flywheel try starting it in gear with your foot on the clutch or jack it up and let her go in top gear not on your own but have someone in da car lol

    I can see the springs when I look in the inspection area, but aren't there springs on both sides.

    Of course you can install the disc backwards ( come on , admit it...we have all done it at least once ! )
    The disc springs can hang up on the flywheel bolts.. My question is why is the fork hitting the bellhousing?
    Smalls,, what bellhousing are you running ?

    Yes they are but one side sits higher than the other so the springs dont hit the flywheel bolts

    The fork isn't hitting the bellhousing, the lever from the clutch arm is...because I turned it around to line up with the 39 pedals I have in my car. This all worked well and good with the old motor and old clutch...stupid aluminum flywheel.

    I usually start them in nuetral get it warmed up, then take it OUTSIDE, pointed away from anything important, start it in gear, run it up a bit, push in the clutch and jam on the brakes. Done it 3 times worked everytime.

    I recently had a brand new clutch disc stick to the flywheel. I went through hell adjusting linkage and modifying arms etc. None of which had been changed before the problem occurred. It would grind shifting into any gear with the clutch in sitting in the garage

    I was ready to pull the engine and trans to see what I had done wrong, when I gave it one last try. Not running, I put it in 1st, stood on the brakes with the clutch in and hit the starter. The disc came unglued and all was well. The disc was new due to a trans change. I don't know if there is a protective coating to protect it on the shelf or not. It was only in there for a few months. The linkage was working just fine all along. The disc had just adhered to the flywheel and there was not enough strain in the garage to break it loose. It has been fine ever since. Clutch disc clearance is measured with feeler gauge so don't expect to see a great deal of clearance with the naked eye.

    This am, I fired her up around 6:30 bright and early in gear...nothing. Reverse, fwd, nada. When I look down in the inspection plate area, the throwout bearing is moving more than enough. Had to get to work. If you guys come up with any other ideas, please let me know. Thanks for the help. BTW, the motor sounds bad ass. :)

    Also spoke with MacVanPelt, he mentioned that the newer style clutch disks are a bit thicker, and that I may try adjusting the clutch bolts that ride on the throwout bearing out an 1/8" or so. (There are only two throwout bearings, and they match the snout on the tranny, one is much smaller, and I have the right one) He said to do it on the bench, but I'm thinking if I'm careful, and turn each of the bolts out the same amount, I can do it in the car?
