ABSTRACT:
A water pump allows adjustment of the drive belt by rotating a portion of the water pump housing. The water pump eliminates the need for additional drive-belt tensioning parts, therefore simplifying maintenance procedures. The pump housing has a support member mounted thereto, with a pump shaft extending therethrough. The support member flange includes eccentrically-formed mounting grooves. The support member is rotated by the loosening of adjustment screws securing it in place. By rotating the support member, the location of the pump shaft is re-oriented and the tension of the drive belt adjusted.
