JD 430 Clutch parts

Of your problem is basically you can't get enough adjustment to allow for disengagement of the pto clutch, that is a common problem on the 420/430. Mine turned out to be a bent clutch rod. Good luck, and talk about bucks the rebuilt 11" disk runs about $159 by itself.

WayneinTN who usually is on this board has said that he has reinforced the rod by welding aomething like another one along side the one that bent.

In my particular case, the clutch rod was rubbing alonside the large or pto drive shaft and had it wore about 1/2 way through. Unless you got a clue on the history of the tractor, it is hard to tell what went on. Someone even had a stick welder inside mine to keep the adjuster in place. I am just replacing all that jury rigged stuff with used. The replacement rod i got has a little jog in it toward the clutch pedal end for clearance by the large drive shaft.

I would say to wait until you broke it in half and had a chance to take a good look see down into the housing where the rod is to try to identify what went wrong.
