Abstract

A fan assembly for an agricultural tractor includes a rotatable fan mechanically driven by a drive shaft coupled to an internal combustion engine. A fan shroud encloses the outer periphery of the fan and is mechanically connected to the engine. A bearing is mounted on the drive shaft and supports the fan shroud so that the drive shaft is rotatable with respect to the fan shroud. The bearing prevents radial and axial movement of the fan shroud relative to the drive shaft. A fan housing is connected to a radiator which is connected to the engine. The fan housing is coupled to an end of the fan shroud by a friction coupler which prevents rotation of the fan shroud.
