Carefully tilt the sander back and lay it down on its side, exposing the three sanding pads on the bottom.

Peel the hook-and-loop sandpaper disc off of the driver assembly.

Use a 3 mm hex key or driver bit to remove the six 11.9 mm-long screws securing the driver pad.

Remove the driver pad from the sanding disc.

Use a flathead screwdriver to pry off and remove the rubber plug in the center of the sanding disc.

Slide a thin 22 mm wrench underneath the sanding disc and clasp it onto the flat part of the motor driveshaft to keep the driveshaft from turning.

Use an 11 mm socket and socket wrench to remove the 16.5 mm-long bolt securing the sanding disc to the motor driveshaft.

Apply counter torque to the driveshaft wrench as you loosen the bolt to keep the sanding disc from spinning.

Take two pry bars and insert them underneath the sanding disc as close to the driveshaft as possible.

Apply pressure to the pry bars in opposite directions to carefully pry the sanding disc off of the driveshaft.

Remove the sanding disc from the floor sander.

Repeat the previous seven steps to remove the other two sanding discs before continuing.

With all three sanding discs removed, use a 4 mm hex key to remove four 25.4 mm-long screws securing the bottom cover and bottom weight.

Lift the bottom weight away from the sander.

Pull the top edge of the bottom cover away from the sander until you have enough space to slide the cover out.

Slide the cover across the bottom of the sander, away from the wheels, and remove it.

Remove the washer from the motor shaft.

Pull the drive pad bearing straight off of the motor shaft.

You may not be able to remove the bearing with your hands. If this is the case, use a bearing puller to remove the bearing.

Remove the snap ring.

Slide the dust fan straight off of the motor shaft.
