Futaba FUEBS3369 Servo Gear Set for BLS151 Servo AS4162 EBS3369  [FUEBS3369]

BLS151 Servo Gear Replacement

This gear set is a replacement accessory intended for the Futaba BLS151 servo family, supplied under the part codes AS4162 and EBS3369. It is an RC-scale component meant for restoring worn gears or preparing a servo for fine tuning, not for any full-scale vehicle application.

Use this set when internal plastic or metal gears show play, stripped teeth, or uneven movement. The set's labeling matches the service parts referenced for BLS151 series servos, so verify your servo model and part codes before ordering. Keep the servo powered off and disconnected from any receiver or power source during replacement.

Installation is a standard gear-swap: open the servo case, note gear stack order and bearing positions, replace the damaged gears with the matching codes, and reassemble while checking mesh and endplay. After reassembly, perform a neutral-centre check and a controlled range test on the bench to confirm smooth operation before mounting the servo back in your model.

The role of this gear set in setup and tuning is simple and practical: renewing gear integrity reduces slop and improves repeatability, which helps maintain predictable steering, throttle, or control surface responses in RC models during setup and track or field tuning.
