Replacement Servo Case for Futaba S3114 & S3154 - FUAS3264  [FUAS3264]

Service part details

The Futaba FUAS3264 case set serves as a replacement housing for Futaba S3114 and S3154 servos and is supplied without retail packing. It is intended for repair work after impact or wear and for routine servicing.

Compatibility: this set is made to fit the S3114 and S3154 servo models listed in the product name. To install, transplant the internal gear train, PCB, and output spline from the original case into the replacement shell, keeping any shims, spacers and part orientation unchanged.

Installation notes: ensure the servo is powered down and removed from the model before opening, organise fasteners so you can restore them to their original locations, take care with the PCB and potentiometer to avoid static or bending damage, and validate gear mesh and spline seating before tightening down. Where possible use the original screws to maintain correct thread engagement.

Tuning and service role: fitting a new case reduces axial play and helps preserve gear alignment, which supports predictable servo response during tuning and setup of small electric RC models.
