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

Gears for Futaba BLS151 Servos

This gear set is supplied as a replacement for the Futaba BLS151 servo family, matching part codes AS4162 and EBS3369. It is intended for RC servo repair and tuning work and is not for use in full-size vehicles.

Install the set when gears show signs of wear such as looseness, chipped teeth, or binding. The product labelling aligns with the service parts for the BLS151 series; confirm your servo model and service codes before ordering. Always disconnect power and receivers before opening the servo case.

Replacement steps are straightforward: open the case, record gear stack and bearing locations, swap in the new gears while preserving orientation, then reassemble checking mesh and endplay. Conduct a neutral position check and a limited-range bench test to ensure everything runs smoothly prior to reinstalling the servo.

New gears restore mechanical integrity, reducing backlash and improving repeatability so your steering, throttle, or control surfaces behave predictably during tuning and operation.
