Hello! Hopefully sombody can help me out here. I have a 2003 komatsu pc210-6 serial #31449 excavator I want to rebuild my control valve specifically the pressure comensation valves but I have noticed I cannot find the part numbers for the hard seals. Only part numbers for the valves themselves and the orings are listed. Anyone have experience rebuilding these valves? Replacing the seals? Maybe someone have the part numbers? I have attached a picture of what I aam looking for....
