Abstract:
A cooling system for a machine, comprising:an engine operatively associated with the machine;a first cooling system adapted for circulating engine coolant through the engine;a heat hanger positioned within the first cooling system for the communication of engine coolant therethrough;at least one axle assembly mounted on the machine;a second cooling system adapted for circulating oil through the axle assembly and through the heat exchanger;a pump positioned within the second cooling system for selectively circulating the oil, said pump being adapted for driving engagement with the engine;a clutch member positioned between the pump and the engine for selectively engaging the drive between the pump and the engine;a sensor adapted for engagement with the engine for sensing the temperature thereof and being operatively connected with the clutch member to engage the clutch when the engine temperature reaches a preselected amount; anda second sensor adapted for engagement with the axle for sensing the temperature thereof and being operatively connected with the clutch member to engage the clutch when the axle temperature reaches a preselected amount.
