Futaba S3114 S3154 Replacement Servo Case Set - FUAS3264  [FUAS3264]

Service replacement housing

The Futaba FUAS3264 servo case set is a direct replacement enclosure for Futaba S3114 and S3154 servos, supplied without retail packing (w/o packing). It is intended as a service part to restore case integrity after wear or impact and for regular maintenance.

Compatibility: this set fits the S3114 and S3154 servo models as noted in the product title. Installation involves moving the internal gear train, PCB, and output spline from the original case into the replacement shell, keeping original part orientation and any shims or spacers in their positions.

Installation notes: switch off power and remove the servo from the model before opening the unit, keep screws grouped and note their locations, handle the PCB and potentiometer gently to avoid static or bending damage, and verify gear mesh and spline engagement during reassembly. Reuse the original screws where possible to maintain correct thread engagement and preload.

Tuning and service role: installing a new case can reduce axial play and help keep gear alignment consistent, which supports reliable servo response during setup and tuning of small-scale electric RC models.
