ABSTRACT:
A stuffing box refacing tool takes the form of a cylinder positioned within the bore and counterbore of a pump stuffing box bearing axially adjustable different sized adaptor rings on its outer periphery with the rings having an outer diameter on the order of the pump stuffing box bore. Shoulders defined within the pump stuffing box and on the cylinder fix the rings and the cylinder axially relative to the box. The cylinder rotatably supports internally, a pilot mandrel which in turn carries the grinding wheel at one end with the end face of the grinding wheel acting to reface the end of the compressor housing stuffing box.
