Replacement Upper and Bottom Case Set for S9074SB/S9156 - Futaba FUEBS3329  [FUEBS3329]

Service Case Pair for Servos

The Futaba FUEBS3329 upper and bottom case set is designed as a direct housing replacement for Futaba S9074SB and S9156 servos. The set rebuilds the external enclosure that holds the gear train, bearings, and the mounting flanges used to secure the servo to the model chassis.

Install this case set when a damaged shell impacts mounting alignment, servo centring, or allows debris to enter. During the swap, confirm gear mesh and bearing seating before final torque on screws, reuse original mounting hardware where it remains serviceable, and check the neutral arm position once the servo is reassembled to maintain correct steering and control geometry.

This accessory supports standard maintenance and tuning operations such as replacing a broken housing after an impact or swapping shells to keep factory mounting distances while servicing internals. Intended for RC servos and model use only.
