Futaba FUSG25 Servo Gear Set for S25 S125 Servos  [FUSG25]

S25 / S125 servo gear set

This Futaba FUSG25 servo gear set is an RC-scale accessory intended as a replacement gear pack for Futaba S25 and S125 servos. It is supplied without outer packing and is intended for hobby-grade servo maintenance and rebuild work.

Use this gear set when internal wear, stripped teeth, or a failed gear train is identified in a S25 or S125 servo; replacing worn gears restores internal alignment and prevents further load on the motor and bearings. The part is supplied as replacement gears rather than a complete servo assembly.

Installation notes: open the servo case carefully, keep track of small parts such as bushings and bearings, compare gear orientation before removal, replace the worn gears with correct alignment, and verify smooth mesh and endplay before re-sealing the case. Perform a low-voltage functional check on the bench before reinstalling in the model.

Tuning and maintenance role: this gear set serves as a spare parts item for routine upkeep, allowing hobbyists to maintain the original servo performance characteristics after mechanical wear, and to minimise downtime during event or track use.
