1953 JD 40 Touch-O-Matic 3-point Lift arm (Single)
I am not a tractor guy, but Father-in-Law left the tractor to his grandson, so I am trying to get the lift arms working.
Quick history the rock shaft housing was broken so I replaced it in hopes that that was to only issue (would not hold Oil, no oil no lift my thoughts).
After replacing lift still would not work. I removed the rock shaft housing and cleaned the bypass valves, pull rob, check valve, and relief valve. and lift started working but when weight was applied by hand it would just jump up and down, but still would not pick up a implement at all.
After tearing back down I noticed the piston bore had large scratches, so order a new housing. Piston had a bur in the top edge so I cleaned it up removing the small bur. Put everything back together but lift still when weight was applied by hand it would just jump up and down, but still would not pick up an implement at all.
I am at a lost now and don't know what else to do. Any advice would be appreciated......
