The adapter (104) is capable of being coupled to a power takeoff device (164). First and second adapter bearings (170, 172) are operatively

A crankshaft-mounted cooling fan is described for an internal combustion engine. The cooling fan has an adapter (104) mounted on the engine's crankshaft (102). The adapter (104) is capable of being coupled to a power takeoff device (164). First and second adapter bearings (170, 172) are operatively connected to the adapter (104) and to a planetary gear assembly (141). The planetary gear assembly (141) is operatively connected to a fan housing (110), which connects to the engine. A clutch assembly (136) is attached to the adapter (104) in a position where it may engage the planetary gear housing (141). A solenoid (132) is connected to the fan housing (110) and is disposed for activating the clutch assembly (136). A fan blade set (174) is coupled to the planet gear assembly (141), which enables the fan blade set (174) to rotate at a faster speed than the engine. The clutch assembly (13) may be engaged or disengaged depending on the operating parameters of the engine or a motor vehicle.
