Futaba FUBS3285 Servo Case Set for S9351/S9155 — Upper & Bottom Replacement Shells  [FUBS3285]

Upper and Bottom Servo Case Set

This Futaba FUBS3285 upper/bottom servo case set provides direct replacement shells specified for use with Futaba S9351 and S9155 servos. The parts are intended as RC-scale accessory components to restore or replace damaged external housings without altering the servo internals.

Use and compatibility are limited to the listed models, S9351 and S9155; do not assume fit with other Futaba or third-party servos. The set focuses on the mechanical enclosure role: protecting gear stacks, keeping internal alignment, and allowing straightforward swap‑out during maintenance.

Installation overview: remove the original case using appropriate drivers, carefully transfer the PCB, gears, and output shaft into the replacement shells, verify gear mesh and end‑play before final screw torque, and confirm normal travel through your transmitter or tester. The shells are intended to be a like‑for‑like enclosure replacement, so standard servicing practices apply.
