I took the hydraulic lift cover off my 420 Tractor, it appears that the
valves maybe stuck. This cylinder has 3 valves unlike a 3000 that only has 2. I was going to just order an after market or rebuilt one, Ford #E0NN477BB but all that comes up is the hydraulic cylinder
with a 3" bore. Mine has a 3 1/2" bore. I was going to try and disassemble it but the plugs have a very small hole, less than 1/8"
diameter except for the main valve in the middle, I can not tell if it has a threaded end to use to pull out the bushing or the valve. Anyone have any ideas or run across this before? I would be happy with a rebuilt assembly but don't know if a 3" bore would even work since mine is 3.5"
