Got the drive off the machine and brought it to a guy that deals with obsolete machines and unusual problems like mine. We disected the thing bit by bit looking for metal shavings, or broken pieces. Crankshafts, pins, top gears and bearings all looked good, so the problem had to be in the hydraulics. Removed the back side of all this and found a couple broken high hats and the ring that keeps them in line, organized and functioning was destroyed. I'll get some pics up later. Right now I've got to go load and haul road millings.
