Hydraulic Fan System (1) Check valve (hydraulic oil cooler bypass). (2) Hydraulic oil cooler. (3) Radiator. (4) Hydraulic fan motor. (5) Filter. (6) Solenoid valve (demand fan). (7) Pressure and flow compensator valve. (8) Hydraulic fan pump. (9) Hydraulic tank.Hydraulic fan pump (8) is mounted to the front housing of the engine on the right side of the machine. Hydraulic fan pump (8) draws oil from hydraulic oil tank (9) through the inlet of the fan pump. High pressure oil then flows to hydraulic fan motor (4). Hydraulic fan motor (4) is located at the rear of the machine between the radiator (3) and the engine. Pressurized oil from hydraulic fan pump (9) flows into the inlet of hydraulic fan motor (4). The flow of the hydraulic oil causes hydraulic fan motor (4) to rotate the fan blades. The rotation of the fan forces cool air to flow through the cooling package. After the hydraulic oil exits hydraulic fan motor (4), the oil flows through a hydraulic oil line to hydraulic oil cooler (2). When the engine is first started and the hydraulic oil is cold, the oil from the piston motor can not easily flow through the hydraulic oil cooler. The oil pressure will increase in the hydraulic oil cooler. The check valve for the hydraulic oil cooler bypass (1) will open. Check valve (1) limits the maximum oil pressure in hydraulic oil cooler (2) to 450 55 kPa (65 8 psi). Case drain oil from piston pump (8) and the case drain from gear motor (4) flow through a hydraulic oil line to hydraulic oil tank (9). The oil from the case drain is filtered through a screen in hydraulic tank (9) .When the temperature of the oil increases, and the pressure of the oil decreases, the force of the spring in check valve (hydraulic oil cooler bypass) (1) for hydraulic oil cooler (2) is greater than the force of the oil pressure that is acting on the spring. This allows the check valve (1) to close. The hydraulic oil flows through hydraulic oil cooler (2), through hydraulic oil filter (5), and then into hydraulic tank (9) .The hydraulic fan system controls the speed of the fan. The hydraulic fan system allows the speed of the fan to decrease in cool ambient temperature or in a light work application. The fan speed is controlled by the four temperature sensors (11), (12), (13), and (14). The sensors send data to engine ECM (10). Engine ECM (10) will interpret the data from the
