Futaba FUEBS3372 BLS153/BLS651 Servo Replacement Gear Set  [FUEBS3372]

Replacement gears for Futaba BLS153 and BLS651

This gear set is supplied as a direct replacement option for Futaba BLS153 and BLS651 servo models, intended for hobby-grade RC servo maintenance and repair. Use this kit when the original internal gears show wear or damage to restore reliable operation.

Installation is straightforward for a hobby workshop: remove the servo horn, open the case, note gear stack orientation, swap the worn gears with the kit components and reassemble. Use the correct driver for the servo case screws and keep track of spacer or washer positions to preserve mesh and neutral position. If you are new to servo work, take notes or photos during disassembly to aid correct reassembly.

As a service part rather than a performance upgrade, replacing worn gears restores mechanical reliability and repeatability in steering and control surfaces. After replacement, verify end-to-end play and adjust horn position if needed to maintain expected neutral alignment in your RC model.
