Futaba S3114/S3154 Service Case for Servo Maintenance - FUAS3264  [FUAS3264]

Replacement enclosure overview

The Futaba FUAS3264 case set provides a replacement outer shell for Futaba S3114 and S3154 servos, offered w/o packing. It is designed for workshop repairs when the original housing is damaged or worn.

Compatibility: intended specifically for the S3114 and S3154 servo models identified in the product name. Fitting the new shell requires transferring the internal gear train, PCB, and output spline from the original unit into the replacement, taking care to preserve part orientation and any shims or spacers.

Installation notes: remove power and detach the servo from the model before disassembly, lay out fasteners to remember their positions, avoid flexing or touching sensitive PCB tracks, and confirm gear mesh and spline alignment during reassembly. Retain original screws where feasible to preserve correct preload and thread engagement.

Tuning and service role: a correctly fitted replacement case reduces unwanted axial play and helps keep gearing aligned, contributing to steady servo behaviour during setup and tuning of small electric RC models.
