S32 and S132 Servo Gear Replacement Kit FUSG132 by Futaba  [FUSG132]

Overview: FUSG132 internals for S32 and S132

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.

Compatibility centres on the S32 and S132 servo families as denoted by the product code. During installation, keep the original sequence and orientation of spacers, shims, and bearings from the donor servo, and verify gear mesh and alignment to ensure smooth operation and minimise free play.

Assembly guidance: carefully dismantle the case using precision screwdrivers, note the location of each component, transfer shims as needed, and check endplay at reassembly. A light, appropriate lubricant on gear surfaces helps cut noise and wear but avoid over-application that attracts debris.

Maintenance benefit: swapping out worn gears is an effective maintenance step to regain steering precision, improve consistency of travel limits, and prolong servo lifespan in hobby applications.
