I have just started working for a mine underground and we use the 1140's as our utility vehicles to get around, i have one that's down with power steering issues. The hydraulic pump is good and the fluids, I have flow and pressure going to both fittings of the steering cylinder but it's not moving at all and it will not turn to the left. the wheel spins fine both ways and no weird noises coming from it. tie rods are attached. Thought I would see if anybody has had this problem before I pull the steering cylinder out
