View of the front of the radiator (7) Oil cooler (8) Oil exits the cooler (9) Oil enters the coolerOil from the piston motor (hydraulic fan) (1) exits the fan motor through line (6) . The oil procedes through a tee for the cooler bypass valve (4) and enters the oil cooler (7) through line (9) . Oil flows from the cooler through line (8) through a second tee for the bypass and on to the hydraulic tank. Cooler bypass valve (4) will open when the oil flow becomes too restrictive. Cooler bypass valve (4) will direct oil around the cooler. The bypass will allow oil to flow from the fan motor hose (6) directly to the return line to the hydraulic tank (5) . The hydraulic oil filter is located between the fan pump and the control valve. There is filter on the fan motor return. Excess oil from the motor will return directly to the hydraulic tank through the case drain to tank hose (2) .
