Servo first gear for listed Futaba models
This is an RC-scale replacement first gear intended for Futaba servos listed in the model string above. Use it when the original first gear shows wear, stripped teeth, or during a servo rebuild to restore reliable mechanical engagement within the gear train.
Compatibility is limited to the S3009, S3010, S3014, S3050, S3070, S3072, S3152 and S3305 servo models as stated in the product title. Verify your servo model before ordering, the part is supplied without retail packing and is intended as a direct swap for the first gear inside the servo gearbox.
Installation notes: remove power and controls, detach the servo horn and casing screws, document gear orientation as you disassemble, lift the gear train carefully and swap the first gear only, then reassemble while checking mesh and endplay. Use light, application-appropriate grease on gear interfaces and avoid contaminating the potentiometer or electronics during the process.
Tuning role: replacing a worn first gear restores mechanical linkage accuracy and reduces backlash introduced by damaged teeth, which can improve the responsiveness and repeatability of servo position control in RC models. After replacement, run calibration checks and verify endpoint and centering under normal load.
