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

Internal gear replacement for Futaba BLS153 and BLS651

This replacement gear set is designed for Futaba BLS153 and BLS651 servos and is intended for hobby RC maintenance and repair tasks. Replace gears when wear or chipped teeth degrade steering precision or cause inconsistent control responses.

Follow a careful disassembly sequence: remove the horn, open the case, note gear positions and orientations, install the new gears from the kit and reassemble. Use the appropriate driver for the servo screws and preserve all shims and washers so gear mesh and neutral offset remain unchanged. If unsure, document the disassembly steps to simplify reassembly.

Consider this item a service component rather than a tuning part; its role is to restore dependable mechanical performance. After refitting, check for smooth travel and correct neutral position before reinstalling the servo in your model.
