Replacement Shell Specification

The Futaba FUBS3285 set contains upper and lower housing shells made to match Futaba S9351 and S9155 servos. These parts function as external enclosures and are not intended to modify the servo's electronics or internal gearing.

Only the S9351 and S9155 are listed for compatibility; verify fit before attempting to install on any other Futaba or third-party model. The shells are intended to protect internals, maintain component alignment, and simplify routine maintenance operations.

Installation summary: remove the original case with suitable tools, transfer the PCB, gear stack, and output shaft into the new shells, check mesh and end-play, then secure the case and confirm normal travel using a transmitter or servo tester.

Should I recalibrate the servo after fitting the new shells?

Yes, you should verify horn alignment and recalibrate end points after reassembly to ensure the servo's travel and centre position match previous settings.

Could the new casing affect heat dissipation?

These shells restore the original enclosure profile so heat dissipation should be similar to the factory case. If cooling is a concern in high-load applications, monitor operating temperatures after installation.

Are these shells suitable for competition use?

The shells are intended as service replacements and will restore standard fit and function. For competitive environments check that the repaired servo meets any event rules regarding modifications and performance before racing.
