Location of the Fan Drive Gear MotorThe fan drive gear motor is located in front of the radiator at the rear of the machine.The fan drive gear motor is a fixed displacement gear motor. The fan drive gear motor is operated by the pressure oil from the gear pump (fan drive). The fan drive gear motor has an internal pressure relief valve. The pressure relief valve will allow pressurized oil to bypass the fan drive gear motor. The pressure relief valve will operate when the oil pressure of the oil that is entering the fan drive gear motor is too high. Oil that flows out of the fan drive gear motor passes through the oil filter and into the case for the hydrostatic piston pump. From the case drain port, the oil flows back to the hydraulic tank.Reversible Fan Motor
A reversible gear motor is available as an attachment. The reversible gear motor is operated by a switch in the cab. The reversible gear motor replaces the standard gear motor. The reversible gear motor allows the operator to reverse the air flow through the radiator and the oil cooler in order to remove dust from the components. The pressure relief valve for the reversible gear motor is located in the reversible fan control valve.Refer to the Operation and Maintenance Manual, "Reversible Fan Control (If equipped)". Also, refer to the Hydraulic System Schematic.
