Futaba FUAS3260 S9450 Servo Replacement Gears AS3260 EBS3233 Upgrade for Tuning  [FUAS3260]

S9450 compatible gear replacement pack

This gear pack is provided for Futaba S9450 servos and is identified by codes FUAS3260 AS3260 EBS3233. It is meant as a service and tuning component to reinstate mechanical precision and to support hobbyists who rebuild or tune servo internals on RC models.

The set addresses mechanical restoration: replacing rounded or chipped teeth, reestablishing correct mesh geometry, and ensuring consistent output behavior during dynamic operation. It is presented solely as a mechanical spare, not a change to electronics or control firmware.

Fitting tips: remove the servo housing and document the internal stack order before fitting, inspect shafts and bearings for wear, set proper mesh and minimal endplay on reassembly, and exercise the servo through full travel to confirm reliable operation before refitting to the model. Recurrent wear may indicate binding or foreign debris in the drive train.

For tuning or rebuild projects, the Futaba FUAS3260 gear set offers a direct way to restore internal mechanical performance in S9450 servos.
