Probable Causes of Problems in the Steering System
The steering pump makes noise or the steering cylinder rod does not move smoothly.
Probable Cause:
The oil level in the tank is low.
The steering hydraulic circuit contains air.
The pump is worn.
The oil passage between the vibratory section and the steering section of the pumps is restricted.
The relief valve in the steering control unit opens at low oil pressure.
The viscosity of the oil is incorrect.
The strainer on the hydraulic oil tank is plugged.Excessive force is required to turn the steering wheel.
Probable Cause:
The relief valve on the steering control unit is open.
The oil level in the tank is low.
The system pressure is low.
The steering control unit covers are too tight.
The steering control unit is faulty.
The oil is cold.
The pump is worn.
The surface may not allow you to make a stationary turn.The machine does not turn when the steering wheel is turned.
Probable Cause:
The oil level in the hydraulic tank is low.
The steering hydraulic circuit contains air.
The pump has failed.
The flow divider valve is not correctly set.
The articulation of the frame is locked.The machine turns too slowly in both directions.
Probable Cause:
The oil flow from the steering pump is insufficient.
The pump suction line contains a restriction.
The operation of the steering control unit is incorrect.
The pump has failed.
The seals in the steering cylinders leak.
The engine speed is low.
The flow divider valve is not correctly set.The machine turns too slowly in only one direction.
Probable Cause:Note: Since the volume of the rod end of the steering cylinder is less than the volume of the head end of the steering cylinder, the machine will articulate faster during a right turn.
The steering control unit contains a restriction.
The steering cylinder rod in the piston is loose.The oil temperature is too high.
Probable Cause:
The viscosity of the oil is incorrect.
Air is mixed with the oil.
The relief valve on the steering control is faulty.
One of the steering lines or one of the steering components contains a restriction.
The propulsion system or the vibratory system contains a problem.
The fan system has failed.The steering wheel turns without the force of the operator.
Probable Cause:
The sleeve valve in the steering control unit is stuck.
The centering springs in the steering control unit are broken or damaged.
The timing of the steering control unit drive is incorrect.
