Retract Servo Gear Kit compatible with Futaba S30G S130G - FUSG130G  [FUSG130G]

Gear Train Replacement Guide

This kit is a direct-replacement gear set intended for Futaba S30G and S130G retract servos used in RC scale models. It focuses on the internal gear components that transfer torque inside retract servos and offers a direct swap when original gears show wear or play.

Installation follows standard hobby servo repair practice: remove the servo horn and shell, inspect gear alignment, replace the worn gear elements with the supplied parts, and confirm smooth rotation before closing the case. Pay close attention to mesh and shaft seating to prevent binding once reassembled.

For tuning and upkeep, clean the gear train, check bearing and shaft runout, and apply a light lubricant only to the gear teeth. Swapping out worn gears can restore consistent retract motion and reduce slop that alters retraction timing and landing behavior.
