Incorrect alignment or an unbalanced condition puts excessive strain on the pump's shaft and/or bearing and will result in early failure of the shaft and/or bearing; The balance of the assembly depends primarily upon the concentricity of the fan clutch and spacers with the pump shaft; Concentricity is not assured when universal type clutches or spacers are used. Universal fan clutches and spacers have a 3/4" pilot hole, so an adapter must be used when installing a water pump with a 5/8" shaft, the adapter bushing is supplied with the unit; So special care must be taken to maintain concentricity with the shaft and the fan clutch. Failure to do so will void warranty; The use of aftermarket (non-OEM) fan spacers are not recommended and will void the warranty of the water pump
