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
with the pump shaft. Concentricity is not assured when universal type clutches are
used. The universal fan clutch has a 3/4" pilot hole, so an adapter must be used
when installing a water pump with a 5/8" shaft. This adapter bushing is supplied
with the unit. These adapter bushings add to the machine tolerances of the
assembly, so special care must be taken to maintain concentricity with the shaft and
the fan clutch.
