(1) Hydraulic oil cooler (2) Cooler bypass valve (3) Low fan speed valve (4) Reversing valve (if equipped) (5) Check valve (6) Fan drive pump (piston pump) (7) Pump compensator valve (8) Reversing fan switch (if equipped) (9) Fan drive motor (piston motor) The main components of the fan hydraulic system are fan drive motor (9) and fan drive pump (6) .Fan drive pump (6) draws oil from hydraulic oil tank. Fan drive pump (6) sends oil to fan drive motor (9). The amount of oil that is sent to the motor by the pump is regulated by the engine ECM. The engine ECM adjusts the current to pump compensator valve (7). The pump compensator valve controls the amount of oil that is sent to fan drive motor (9). When more oil is sent to fan drive motor (9), the fan turns faster.The oil from the outlet side of the fan drive motor flows through hydraulic oil cooler (1). The oil from the hydraulic oil cooler combines with the oil from the case drain of the fan drive pump. The combined oil then returns to hydraulic oil tank.When the hydraulic oil is cold, the oil from the outlet side of fan drive motor (9) will bypass hydraulic oil cooler (1) through cooler bypass valve (2). After the hydraulic oil warms, the oil will flow through the hydraulic oil cooler in order to keep the oil at a predetermined temperature.
