Abstract: A combination in-line type water pump and power steering pump assembly which includes a power steering shaft with an outer end portion extending into a pumping chamber of the water pump. The outer end portion of the shaft is configured to removably support a tubular shaft sleeve and a water pump impeller thereon. A seal annulus is mounted in the pump housing and encompasses the shaft sleeve in water tight relation therewith at an inwardly location from the impeller. The impeller and the seal annulus are removable from the sleeve by application of an axial force to slip the impeller and seal annulus axially along the outer end of the shaft sleeve.

Abstract: An in-line combination steering pump with a shaft and water pump having a housing defining a pumping chamber into which the outer end of the shaft extends. 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. For replacement, the seal and bushing are removable over the outer end of the shaft after the impeller is removed.
