I have seen utube videos on removing rockshaft cover. But nothing on trouble shooting or diagnostic. Hopefully it is something simple, and won't take a long time to get parts. I have researched a little, the 2010 seems to have had it's problems. I also read most problems were corrected by 1963. Right now that seems to be the only big problem. It has been converted to alternator, and negative ground. New battery, fresh plugs, wires, dist cap and rotor. Gauges installed, oil pressure gauge leaking. Hydraulics are strong. Bucket doesn't have Hydraulics, manual dump, power steering. Needs lever knobs, lights, fuel gauge.
