ABSTRACT:
A hydraulic motor for driving a hydraulically driven fan system in a combustion engine includes both an oil pump and water pump in combination. The pump body and a pump cover together define a hollow chamber within which a shaft is rotatably mounted, the shaft supporting an oil pump rotor. A thrust plate in the hollow chamber coaxially aligns the pump body and pump cover and supports a first bearing for the shaft. The water pump is mounted in the pump cover and includes an impeller mounted on the shaft.
