(8) Steering pump Steering pump (8) is mounted on the upper left of the engine flywheel housing. The steering pump is an axial piston pump with overcenter capability. The output direction and flow of the steering pump is controlled by steering pump control valve (1).Steering charge pump (2) is located on the rear of steering pump (8), which is mounted on the upper left of the engine flywheel housing. The steering charge pump is an axial piston pump. This pump provides charge oil for the steering hydraulic circuit.Steering Motor
Illustration 3 g02152435
(3) Steering motor Steering motor (3) is installed into the front of the main case on the left side of the machine. This motor is a fixed displacement bent axis motor which can turn in either direction. The direction of rotation is determined by the input flow to the motor from the steering pump. The output shaft of the steering motor turns the steering differential, which causes the machine to turn.Steering Charge Filter
Illustration 4 g03011936
(5) Steering charge filter Steering charge oil filter (5) is mounted at the rear of the tractor under the fuel tank. The charge oil filter traps debris that is in the oil in order to prevent damage to the hydraulic system components.Steering Controls

(7) Steering control lever Steering control lever (7) is located on the left console in the cab area. In FORWARD gear, push the steering control lever away from the operator for STEER LEFT. In FORWARD gear, pull the steering control lever toward the operator for STEER RIGHT. The position sensors in the steering control lever send a signal to power train ECM (4). Power train ECM (4) controls the response of the steering hydraulic system.Pressure Ports

(HC) Pressure port
(HD) Pressure port Pressure ports (HC) and (HD) are located on steering motor (3).Pressure port (HD) measures the pressure of the oil that is in the right steering loop. Pressure port (HC) measures the pressure of the oil that is in the left steering loop.

(8) Steering pump
(X1) Pressure port
(X2) Pressure port Pressure ports (X1) and (X2) are located on steering pump (8), as shown.Pressure ports (X2) measures the pressure of the oil that is acting on the actuator piston when the tractor is steering to the right. Pressure port (X1) measures the pressure of the oil that is acting on the actuator when the tractor is steering to the left .

(SOS) Pressure port and oil sampling port
(K) Charge pump pressure port
(5) Steering charge filter Pressure port (SOS) and (K) are located on steering charge filter (5), as shown.Pressure port (K) is used to measure the pressure of the charge oil that exits the steering charge filter. Pressure port (SOS) is used to draw oil samples before the oil is filtered.
