FQ Majestic Tear-Down Instructions
After tearing down my Filter Queen to replace the cord and the motor batting, I decided it might be helpful for others to offer a step-by-step procedure for tearing down the motor unit to gain access to the wiring, motor components or batting. Going in blind wasn't all that bad, but I could have saved some effort if I had known what I know now. The only tool necessary is a Phillips screwdriver and maybe a pair of pliers.
1. Open the canister's latches and lift out the motor assembly.
2. remove the screw at the pointed end of the cone-shaped basket, take off the basket and discard disposable filters.
4. Set the motor assembly on a flat surface, remove the exhaust port cover, and remove the three screws surrounding the exhaust port. If the unit has an older style pedal type power switch, carefully pull the rubber cover off of it in order for the pedal to fit through the opening on the top motor cover.
5. Carefully lift the motor cover off. You will still need to disconnect several wires before you can completely separate the outer top cover from the motor. Be sure to label the wires before you undo the wire nuts holding them together so you'll know what connects where when you go to reassemble it.
6. To access the motor in order to replace the brushes, unscrew the three bolts that hold the two halves of the motor cover together.
To reassemble, just reverse the steps above, replacing the paper filters as you go. If you replace the motor batting, you will need to save and reuse the cardboard ring that was underneath the old batting. The bolts holding the two halves of the motor cover together go with the nuts at the bottom. One of the more challenging parts of reassembly is lining up the screw holes on the top of the motor cover with those on the metal basket and the serial number ring that go in the exhaust port. They are unevenly spaced so they only line up one way.
