Futaba FUSG9303 Servos S9302 S9303 Internal Gear Replacement  [FUSG9303]

Service kit for S9302 / S9303 internal gears

This kit provides replacement internal gears for S9302 and S9303 servos and is shipped without retail packing. It helps recover precise, repeatable movement and reduces gear backlash in hobby servos used on scale models.

Install this set when worn teeth, excessive free play, or uneven motion compromise steering or control surfaces. The parts are intended for maintenance and full rebuilds, returning stable positioning and the servo's intended feel without changing its rated torque or speed.

Installation notes:

• Record gear positions during disassembly so each gear is reinstalled with the correct orientation.
• Check nearby parts such as bearings and output shafts for wear and swap any defective items before reassembly to avoid early issues.
• After rebuilding, verify gear mesh and end play at the control horn to ensure smooth, bind-free operation.
