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.
