They disassembled the motor to do this.

Depending upon the design of the back plate / cap the motor usually provides access to a squared off portion of the shaft so you can use a wrench to turn the shaft or secure it for removing / installing the impeller. In the most common design a wrench can be slid onto the shaft behind the rotating switch.
