You are missing the point....if the cone is loose...with or without damaging the impeller...THE PUMP DOES NOT WORK..!!!! The cone and the clearence between it and the impeller blades,size of the hole in the involute etc is what makes it a 'pump' Vs just a 'paddle wheel'...get it!....an engine with a metal impeller pump but a loose cone WILL STILL OVERHEAT..! :rolleyes:
