Futaba FUSG135SH servo gear set (w/o packing)  [FUSG135SH]

Replacement servo gear set

This Futaba FUSG135SH servo gear set (w/o packing) is a direct replacement accessory intended for use on Futaba-brand RC servos. The write-up focuses on practical details hobbyists need to decide whether this gear set fits a repair or tuning task without implying compatibility with non-RC equipment.

Use this gear set when a servo exhibits gear wear, stripped teeth, or increased backlash. The set is presented without retail packing, suitable for technicians or modders who need spare gears for in-field fixes or bench repairs. It supports routine maintenance and tuning workflows by restoring mechanical engagement and reducing play in the output shaft.

Installation notes: inspect the servo case and output spline for damage before swapping gears, remove the horn and secure the output shaft while changing internal gears, and verify centring and range after reassembly. For tuning, confirm servo endplay and mesh with the driven linkage rather than relying solely on electronic trims.
