Futaba Servo Gear Replacement for S32 & S132 — FUSG132  [FUSG132]

FUSG132 gears — purpose and maintenance

This Futaba FUSG132 servo gear set is an RC-scale replacement gear kit intended for use with Futaba S32 and S132 servos. It serves as a direct internal gear replacement to address wear, reduce backlash, and restore centring behaviour in hobby servos without altering electrical or control systems.

The pack is tailored to the S32 and S132 families as shown by the product code. During installation, preserve the original order of spacers, shims, and bearings from the donor unit, and check gear mesh and alignment carefully to maintain smooth, low-play operation.

Practical installation guidance: disassemble using small screwdrivers, keep track of component locations, transplant shims where required, and verify endplay on reassembly. Apply only a small amount of suitable grease at gear interfaces to limit noise and wear while avoiding buildup of dust-attracting residue.

Maintenance advantage: replacing degraded gear sets restores repeatability in steering and control surfaces, helping to retain accurate endpoints and extending the usable life of the servo within routine servicing cycles.
