Futaba FUSG23 Internal Servo Gear Set (W/O PACKING)  [FUSG23]

Replacement gears for S23 servos

The Futaba FUSG23 servo gear set is a direct spare for Futaba S23 series servos, supplied without retail packing. It is an RC-scale replacement intended to swap out worn internal gears and restore mechanical function without fitting a new servo.

Fit this gear set when you notice excessive clearance, gear backlash, or stripped teeth inside an S23 servo. The set restores correct gear mesh and ensures torque is transmitted from the motor to the output spline, helping the servo keep expected centring and control response in RC models.

Installation notes: carefully dismantle the servo on a clean bench, organise shims and small screws, and verify gear mesh and endplay before reassembly. Use a small amount of suitable gear grease only on the contact faces, keep bearing surfaces free of lubricant, and run the servo slowly to confirm smooth motion before reinstalling in the model.

Tuning and fitment: replacing internal gears can change feel and endplay slightly; inspect for binding after installation and confirm that electrical and mechanical interfaces remain secure. This item is sold as an internal replacement gear set for scale RC servos and is not intended for full-size or non-hobby applications.
