Futaba FUEBS3372 BLS153/BLS651 Servo Gear Set AS4165 EBS3372  [FUEBS3372]

Futaba BLS153/BLS651 Servo Gear Set

This gear set is presented as a direct replacement option for Futaba BLS153 and BLS651 servo models, intended for hobby-grade RC servo maintenance and repair. It is described as a gear kit matching the internal drivetrain of those listed servos, so use it when original gears show wear or damage.

Installation is straightforward for a hobby workshop: remove the servo horn, open the case, note the 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 lack experience, take notes or photos during disassembly to ensure correct reassembly.

In tuning and maintenance workflows this set serves as a service part rather than a performance upgrade; replacing worn gears restores mechanical reliability and repeatability in steering and control surfaces. After replacement, check end-to-end play and adjust horn position if needed to maintain expected neutral alignment in your RC model.
