The water pump housing supports an annular adapter member for supporting a seal which encompasses the shaft and is press mounted in the adapter. An impeller is removably secured to the outer end of the shaft adjacent the seal. A bushing encompasses the shaft between the seal and the impeller and is compressed by attachment of the impeller to the shaft so as press the seal firmly into the adapter.
