Replacing the Drive Motor

Procedure
The drive motor and flywheel are balanced as a matched pair. Since the flywheel is balanced
to a specific motor, flywheels should not be removed from one and installed on a different
motor. If the drive motor is replaced, the drive motor and flywheel should be replaced as a unit.
