Futaba S32/S132 Internal Servo Gear Set FUSG132  [FUSG132]

Futaba S32 and S132 gear set notes

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 centering behaviour in hobby servos without altering electrical or control systems.

Compatibility is focused on the S32 and S132 servo families as indicated by the model designation. When fitting the gear set, retain the original order and orientation of spacers, shims, and bearings from the donor servo, and take note of gear mesh and alignment to maintain smooth movement and minimise play.

Installation notes: disassemble the servo carefully using small drivers, document the position of each part, transfer any existing shims, and reassemble while checking endplay. Light, appropriate grease on gear interfaces can reduce noise and wear, but avoid over-lubrication that can attract debris.

Role in tuning and maintenance: replacing worn gears is a practical way to recover lost precision in steering or control surfaces on RC models, improve repeatability of endpoints, and extend the service life of the servo as part of routine maintenance.
