Futaba FUAS4109 S3001 Upper & Bottom Servo Housing Replacement  [FUAS4109]

Replacement Housing for S3001 Servos

This replacement upper and bottom case is produced to fit Futaba S3001 servos and functions as a direct housing swap when the original shell is damaged or worn. It keeps internal parts aligned and shields the electronics during routine servicing.

Intended compatibility is with S3001-class servos as shown by the model name, so confirm your servo model before ordering. The package supplies only the two shell halves; gears, bearings, seals, and screws are excluded and must be salvaged from the original unit or obtained separately.

Installation guidance: disconnect power and remove the servo from the model, record gear stack and potentiometer orientation, carefully move the internal gear train and circuit board into the replacement halves, then refit the covers and secure with screws. Be cautious with wiring and the potentiometer link to avoid shifting neutral; perform neutral and travel checks after reassembly.

Service benefit: fitting a new case removes play caused by deformed mounts, preserves gear mesh alignment, and helps recover consistent servo response after maintenance. Replace the housing when the existing shell no longer holds internals securely.
