Futaba FUEBS3329 Upper & Bottom Shells for S9074SB and S9156  [FUEBS3329]

Upper and Lower Shell Replacement

The Futaba FUEBS3329 upper and bottom shell pair is intended for direct replacement on Futaba S9074SB and S9156 servos. This accessory rebuilds the outer housing that secures internal gears, bearings, and the mounting tabs that fix the servo to the model chassis.

Use these shells when the existing housing is damaged, misaligned, or allows contamination. When fitting, confirm correct gear mesh and bearing alignment before finalising screws, keep original mounting hardware if serviceable, and verify the servo arm is centred after reassembly to ensure reliable steering geometry.

These cases assist routine upkeep and tuning activities such as replacing a split housing after an impact or swapping enclosures to maintain factory mounting distances during gear service. The product is designed for hobby RC servo applications only.
