New to the forum. First post. I'm working on a 77 that has extensive free play in the clutch pedal travel. The adjustment screw was recessed into the nut on the clutch rod 3/8" and there was only about 1-1/2" of useable movement with 4"+ of freeplay. The flywheel, pressure plate and clutch disk look good, but the fork was hitting the pressure plate finger adjustment screws. Nothing looks bent. I have checked the distance from the crankshaft to the transmission by reinstalling the input shaft. I have installed a new clutch disk, pressure plate and throw out bearing with parts from Korves according to the tractor serial number. The issue is slightly worse with the new parts. I have adjusted the clutch fingers out towards the transmission so they are 2-1/16 away from the flywheel surface with the disk installed. This made up some space, but still not much useable pedal travel. The clutch does release just fine, but this condition isn't correct.
I know the clutch fork was on a hard angle, since it was rubbing the pressure plate, but why? Obviously the throwout bearing is too far away from the fingers.
Several things come to mind. Somehow could it have the wrong throwout bearing carrier sleeve, being too short? There is 1-1/16" from the shoulder for the bearing to where the flange contacts the fork. The fork doesn't seem bent. Moving it's pivot point in the bell housing toward the engine seems like it would help as well. Are the replacement parts correct? Surely I am not the only one with this issue, especially since new parts didn't correct anything.
I'm totally stumped on this one.
