There are two motor support brackets: one in front, one back (shown in the first image)

Each bracket is attached to the motor by two screws (one on each side).

Using a #2 Phillips screwdriver, remove the four screws (circled in yellow in the second and third images) which attach the two motor support brackets.

Take care to place your hand under the support bracket when removing the second screw as they will fall out and could damage the finish.
