The set screws are meant to be used only once. If you re-use the same screws, the rotor will loosen, and your bilge pump will likely get a workout.
Thanks for the warning. Well taken. I used new set screws. But I do not trust them anyway. Therefore I secure the rotor additionally with a Two-Piece Clamp-On Shaft Collar placed directly against the rotor.
