jumpy clutch

brakes done, quite a project, my allis b 1951 has a jumpy clutch i call it, i got used to it but would be afraid to put any one else on it, if you let the clutch out slowly and stop when you feel the first sign of engagement you take off smooth but if you are not very careful it jumps and kills the engine, there is no clutch rivet on flywheel noise and clutch doesnt slip it grabs. is this something allis chalmers normally do, is there an adjustment?. 2nd gear is more forgiving, could it be something else? motor runs good no noises no smoke, when you go up a hill the engine picks up and doesnt die so the ??? seems alright. got any ideas on how to pinpoint the problem, clutch, etc. cant think of the part with the spinning balls.
 
If the three pressure plate fingers do not touch the throw-out bearing at exactly the same time, it will do that as well. Adjust them all to be the same height.
 
how do i make that adjustment, didnt see that in manual only saw to adjust two screws in a small opening to make sure two spaces are
1/4 inch apart, i havent even looked in this small opening where clutch pedal rod goes in to meet the throw out bearing, but would like
to make the letting out of the clutch a little smoother, please elaborate. appreciate the input
 
good point, on fords there was a hole under flywheel and oil would drip if it was getting in that section, i dont see any sign of oil, what do i look for and is there anything i can do short of seals? and new clutch, i havent driven it much maybe miles on it will improve problem, what do you think?
 
Using it may help if from oil or rust. If from the fingers on the pressure plate not being even it will not help and maybe get worse
 
I've noticed on sevral B's the clutch disc is a solid center disc. A Sprung (spring) center clutch disk vs a solid may help.
 
finally found the opening to adjust the clutch fingers , if im right its directly under the tractor and has a pop off cover and inside is a grease fitting, working under and looking up is not easy for me i get dizzy i think i see nuts to loosen , looks like ill have to turn engine to get at 3 adjustments, it would help if someone knows the size wrench ill need to loosen and tighten again after adjusting with a screw driver. a screw driver is what you use to do the adjustment correct? trying to cut my up/down time, looks like some cleanup neecesssary first
 
any one know the proper tools needed to make the adjustment on the clutch, hard to see in there anyone ever seen a tutorial on doing this?

Robert, I've never tried this on a B clutch, with the tractor all together. Adjusting the release lever height is usually done when installing a new clutch kit, and, before re-coupling the tractor.

It is critical, that not only are the release levers all at the same height, but that the height itself is correct. This is usually spec'd as a height above the flywheel or from the pressure plate where it contacts the disc.

May want to consider all this before trying through an access hole. Don't wanna end up more uneven than you start. Usually small adjustments to the screw move the levers pretty quick.
 
looked in access opening and haveing trouble seeing how to adjust, will have to somehow clean it up in there, has anyone have a picture of what is in there to help me orient myself and also what size wrench? open end or box?, cant find a tutorial on this so far, tuttorials help me immensely. thank all for input.
 
im about to jack it up and take some play out of rear wheel by adding washer, will keep loose wheel in mind, you mean it is loose on the splines due to wear?
