1. Remove the servo assembly from the vehicle.
2. Place the assembly on a bench with the cover in the up position, remove the servo cover screws and lift off the cover. DO NOT INVERT the servo assembly once the cover has been removed.
3. Drill a 3/16" (4.7 mm) hole through the center of "C" of the logo on the cover.
4. Clean the cover of drill filings.
