I have a Kabota RX-501. It has been a great worker for 5 or so years. Its grey market which brings all those GR issues with it. My issue is some of the hydraulic functions have stopped functioning. Cant tell weather its from the boom sensors and or wiring or hydraulic failure of some kind.
Symptoms: boom functions moving down but NOT up, boom articulation functions to the right but NOT to the left, thumb opens but will NOT close.
The bucket opens and closes, turret (cab) rotates left and right, blade works up and down, tracks work forward and reverse.
There is an alarm standing is at all times since these functions stopped working. A decal picture inside the cab, in Japanese,` has an arrow pointing to this alarm light on the control panel and another associated picture showing the boom and the bucket crashing into the cab front window. The continuity of the cable harness to the boom sensors
checks out good.
I have changed the hydraulic filters and fluid with no change in any of the symptoms.
Any suggestions????????? :Banghead
