Futaba FUBS3321 Servo Case Set for S3114/S3154  [FUBS3321]

Servo case set for S3114/S3154

This servo case set is a direct accessory item intended for use with Futaba S3114 and S3154 RC servos. It provides replacement external housings to restore a worn case or to refresh an existing servo body without changing internal electronics. The text focuses on practical fit, basic installation considerations, and how the case supports setup and tuning tasks.

Installation is mechanical and requires removing the servo horn and screws, transferring internal components into the replacement shells, and reassembling carefully to preserve gear mesh and bearing alignment. Keep parts organized during disassembly and avoid forcing bearings or gear stacks to prevent damage to internal components.

In a tuning context the case set helps maintain consistent mounting and alignment when servos are replaced during chassis setup. Using a matched case for the same servo model preserves mounting points and reduces the need to rework linkages or brackets, making it useful for routine maintenance and swap-outs during trackside adjustments.
