Procedure

1. With the rotating assembly removed from the pump casing, remove the impeller lock screw and unscrew the impeller from the shaft.
2. The impeller was installed at the factory using Loctite and so may be fairly difficult to unscrew.
3. A propane torch can be used to ease loosening the screw if necessary.
4. Use the impeller removal tool to fix the shaft from rotating, and use a metal bar or piece of wood to rotate the impeller counter-clockwise until it is free of the shaft.
5. It may be necessary to pound the bar with a hammer to loosen the impeller.
6. Inspect the impeller and replace it if necessary.
