2. Fit the clip nut of the removed motor onto the new motor, ensuring an identical
position of the 8x8 hole in the fan hood.
3. Push the new encoder onto the clean shaft end of the motor until it makes
contact with the shaft collar and/or spring plate on the motor.
4. The mounting collar of the encoder must point towards the shaft end.
5. Screw on the encoder mount on the motor.
6. Secure the encoder inner ring by tightening the stud on the motor shaft.
