It is not necessary to remove all of the grease from the output gear, only
the excess grease. Do not use solvents to clean the output gear.
1. Remove each servo.
2. Remove excess grease build‐up from the single servo output gear using a lint‐free cloth.
3. Apply a thin coat of grease to the servo output gear using a brush or other applicator (see
note above).
4. Reinstall the servos.
5. Rotate control surfaces through their range of motion to ensure freedom of movement.
