Hi there! I hope everyone is doing well and staying safe!
I have a 2001 Komatsu D31PX-21 bulldozer. Does anyone have any suggestions on what would cause the machine to abruptly stop meaning the machine came to a sudden stop while backing up. The engine cranks and runs fine and the gears will shift but nothing works. The machine won’t move forward nor will it reverse. The work equipment (blade lever) also stoped suddenly at the time and the travel. Both lock-out levers are in the up position and still nothing works. I’ve checked hydraulic oil level and it’s full and I’ve also checked for blown fuses and none are blown. Sounds like it’s something simple like a bad safety switch, solenoid etc but don’t know where to start looking.
Any help will be greatly appreciated!
