(24) Steering Charge Filter (25) Filter Bypass Switch (26) Charge Pressure SensorNote: The filter bypass switch is located on the housing between the filter inlet port and the filter outlet port.Filter bypass switch (25) is located in the filter housing for steering charge filter (24) , as shown. When the filter element is full of debris and the bypass valve opens, filter bypass switch (25) will open. The operator will be notified with a warning at normal operating temperature, inspect the filter element for restrictions.Charge pressure sensor (26) monitors the charge oil pressure before the charge oil flows through the charge filter (24) , as shown.Power Train ECM
Illustration 17 g01137467
(27) Power Train ECMPower train ECM (27) is located behind a panel at the rear of the operator's station. The power train ECM receives electrical signals. Then, the ECM sends electrical signals in order to control the response of the steering hydraulic system.Rotary Position Sensor on the Steering Control Lever

(33) Reversing SwitchReversing switch (33) is located on the right console in front of the blade control lever. The reversing switch allows the operator to manually reverse the direction of the fan.Pressure Sensor for the Fan Drive Pump
Illustration 21 g01137482
(34) Fan Drive Pump Pressure Sensor (35) Fan Drive PumpFan drive pump pressure sensor (34) measures the pressure at the outlet of the fan pump. This is the oil that is delivered to the fan motor. This pressure sensor sends a signal to the engine ECM. The engine ECM uses this signal to control pump output.Fan drive pump pressure sensor (34) is located on the fan drive pump (35) , as shown.Solenoid for Reversing Valve (If Equipped)
