Futaba FUEBS3369 BLS151 Internal Gear Kit Compatible with BLS151 Servos  [FUEBS3369]

FUEBS3369 Gear Kit for BLS151

This replacement gear kit is intended for the Futaba BLS151 servo family and carries the service references AS4162 and EBS3369. It is an RC-scale component for restoring worn gears and refining servo response during tuning and set up.

Apply this kit when you observe gear backlash, stripped teeth, odd noises, or inconsistent rotation. The label matches the referenced service parts for BLS151 units; verify your servo model and part numbers before purchase. Always ensure the servo is disconnected from power and any receivers before servicing.

Installation is a standard internal gear replacement: remove the case, note the exact gear order and bearing positions, fit the replacement gears maintaining original orientation, then reassemble while checking gear mesh and endplay. After assembly perform a neutral-centre check and a cautious bench test to confirm smooth function prior to refitting the servo.

Renewing the gear set reduces play and improves repeatability, which supports consistent control inputs when fine tuning steering, throttle, or control surfaces on RC models.
