On rebuild of Firestone 10 hp (scott Atwater 1956) It was running hot. I took power head off and opened up the water pump to find a new impeller, but there is no key or pin to drive the impeller. There is a double keyway in the impeller proper, but no apparent way to attach it to the shaft. There are two flats machined in the shaft, but again, no way that I can see to attach the impeller Any help? Any suggestions sincerely appreciated. Thanks, guys.
