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

Upper/Bottom Servo Case Set

This Futaba FUEBS3329 upper and bottom case set is intended for use with Futaba S9074SB and S9156 servos as a direct housing replacement. Designed as an accessory part for RC-scale servos, the set restores the external shell that holds internal gear stacks, bearings, and the mounting flanges that secure the servo to the model chassis.

Use this case set when a damaged or worn shell affects mounting alignment, servo centring, or exposes internal components to contamination. During installation, confirm gear mesh and bearing alignment before finalising screws, keep original mounting hardware when possible, and verify neutral arm position after reassembly to maintain predictable steering and control linkage geometry.

The item supports routine maintenance and tuning tasks such as replacing a cracked housing after an impact or swapping shells to retain factory mounting distances while servicing internal gears. This accessory is strictly for RC servos and related model use.
