1. Slide the wet-end on to the motor shaft
2. Hold the impeller inside the wet-end
3. Turn the shaft of the motor clockwise until the wet-end is pulled up to the motor
4. Tighten the four 1/4" thru bolts that attach to the legs of the wet-end
5. Hold the impeller and tighten the shaft to "cinch" it up.
Thats it, you're done!
