Futaba FUSG9303 Replacement Gear Set for S9302 and S9303 Servos  [FUSG9303]

Replacement gear train for S9302 and S9303

This gear set is an RC-scale replacement intended for S9302 and S9303 servos, supplied without retail packing. It is engineered to replace worn internal gears so steering and control surfaces regain smooth, repeatable motion while reducing lash in hobby-grade servos used on scale models.

Fit this set when internal wear, stripped teeth, or excessive play begins to affect precision or centering. The components serve as maintenance parts during servo rebuilds and routine upkeep, restoring consistent positioning and control feel without altering the servo's factory-rated speed or torque.

Installation notes:

• Carefully note gear orientation during disassembly so each element returns to its original index position.
• Inspect nearby parts such as bearings and output shafts for signs of wear before reassembly, and replace any damaged items to prevent early failure.
• After reassembly, check gear mesh and end play at the control horn to confirm smooth operation and avoid binding.
