Next step includes threading the Plastic Screw through the Magnet and install the Washer. Here you can see how the back side of the magnet is counter-sunk to accommodate the taper on screw.
Next, slide the Wet Side Frame over the magnet assembly.
Install the Propeller over the Plastic Screw and hand tighten the Plastic Nut.
Finally, replace the Nozzle and Wet Side Cover and VOILA - A happy Vortech!!
