Abstract
A water pump having a water pump housing, a housing flange mounted on the water pump housing, and a pump rotor rotatably journaled in the housing. A hollow stud projects axially outwardly from the flange, a drive and bearing assembly for supporting the pump rotor comprising a roller bearing supported on the outer peripheral surface of the hollow stud, and a pulley rotatably supported by the roller bearing on the hollow stud of the housing flange. A shaft supports the pump rotor and passes through the hollow stud. A coupling element connects the pulley to the shaft in a torsion-proof manner and simultaneously centers the shaft whereby the roller bearing is tightened to eliminate axial play.
