Abstract

An ice machine pump rebuild kit which enables a repair person to replace the electric motor for the pump and rebuild the pump by providing a kit which enables the drive motor and pump impeller to be replaced from a minimum inventory of replacement components. The kit includes a plurality of pump impellers constructed of plastic material having sufficient rigidity but yet enough flexibility to enable the impeller to slip over and frictionally engage the motor shaft with the impeller shank including a V-shaped slot oriented radially therein to enable the impeller shank to expand to receive and frictionally grip the motor shaft in a secure manner.
