The hydraulic oil cooler is mounted in front of the engine. Hydraulic oil cooler (2) is integrated with the engine coolant radiator, and the air-to-air aftercooler.
The hydraulic oil flows through the hydraulic oil cooler in order to maintain the operating temperature of the oil. A fan that is driven by the engine pulls air through the radiator. A portion of the return oil from the main control valves flows through the bypass check valve and through line (3). From line (3) the return oil flows to inlet (1) and to hydraulic oil cooler (2). The hydraulic oil that is cooled by the hydraulic oil cooler flows through outlet (5), return line (4), and the return filter to the hydraulic tank.
