Gsa Greasing Procedure; Gdc Rvsm Altitude Inspection - Garmin G1000 Maintenance Manual

9.6 GSA GREASING PROCEDURE

Clean and apply grease Aeroshell 33MS (preferred), or Aeroshell 17 to output
gear every 1000 hours or 3 years, whichever comes first.
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. Re-install the servos.
5. Rotate control surfaces through their range of motion to ensure freedom of movement.
