ABSTRACT:
An engine water pump assembly is formed of a rotatable shaft divided along its length into a bearing portion terminating in a drive connection and a sealing portion terminating in an impeller end upon which a water impeller is mounted. A tubular, journal-type bearing surrounds the shaft bearing portion. A pump housing surrounds the shaft and bearing and has an integral, enlarged chamber formed on one end within which the impeller is located. The opposite end of the housing has an opening through which the shaft drive connection extends. The bearing has an integral, annular flange which surrounds a part of the shaft sealing portion. A seal mounted upon the shaft sealing portion seals against the flange to prevent the flow of water from the impeller chamber to the bearing part of the housing and its opening. The housing is molded around the bearing to form an integral subassembly. The shaft and seal may be pre-assembled and then inserted, as a subassembly, through the housing chamber towards and into the bearing and its flange.
