Hello, i have a Komatsu PC78us-8 with some hydraulic trouble, suddenly when i was belting it stopped belting. Almost all functions are gone but blade and swing works. If i force blade upwards and runs on overpressure i can lift the boom. The other functions works then aswell but i have to run bladelift + boomlift + other function i want to use. Any1 got some tips?
Good day If you can post a hydraulic schematic we can try to help out. Kind regards Uffex
Whats the Serial Number?
Good day, This is PC78US-8 (Blade specification) hydraulic Circuit Diagram for your reference. Regards.
Good day Can you check that the control for the blade & slew are nor mechanical? Kind regards Uffex
