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

Replacement Upper and Bottom Housing

This Futaba FUEBS3329 upper and bottom case set is made for use with Futaba S9074SB and S9156 servos as a direct housing replacement. As an accessory for RC-scale servos, the pair restores the external shell that supports internal gear stacks, bearings, and the mounting flanges used to attach the servo to the model chassis.

Fit this case set when a cracked or worn shell affects mounting alignment, servo centring, or exposes internal components to dirt. During installation, check gear mesh and bearing seating before tightening screws, retain original mounting hardware where possible, and confirm the neutral arm position after reassembly to keep steering and control linkages predictable.

The component supports routine maintenance and setup tasks such as replacing a damaged housing after impact or swapping shells to preserve factory mounting distances while servicing internal gears. This accessory is intended solely for RC servos and related model use.
