Power Train Oil Cooler
(1) Coolant Inlet
(2) Coolant Outlet
(3) Oil Inlet
(4) Oil Outlet Power train oil cooler (22) is located under the radiator at the front of the machine. Power train oil cooler (22) s an oil to water type cooler.Power train system oil with a high temperature comes from the torque converter outlet relief valve. The oil enters power train oil cooler (14) at oil inlet (3). The oil flows around the many tubes inside the cooler.Engine coolant enters the cooler through cooler inlet (1). As the coolant flows through the tubes inside power train oil cooler (22), the coolant absorbs the heat from the oil. Coolant leaves power train oil cooler (22) through coolant outlet (2). The coolant is then cooled by the cooling system of the engine.After the power train oil flows around the tubes in power train oil cooler (14), the oil flows out of oil outlet (4). The oil has a lower temperature. The oil then flows to the distribution manifold on the front of the bevel gear case. The manifold divides the flow between the transmission and the brakes for lubrication and cooling.
