I have a 1975 John Deere backhoe 310. I'm having problems with the Pressure Control Valve. There is a nylon o-ring type washer that mounts in the valve.
The pressure control valve mounts to the side of the housing. I'm not getting much service before it blows out or whatever...
How much is a 1975 John Deer 310 Backhoe selling for, assuming it runs and everything works on it. Runs good and hydraulics work well. 3 cylinder diesel.
