This is the replacement Futaba Servo Gear Set for the S9251 and S9256 Digital Servos. These are the first, second and third plastic gears for the servo that fit on shafts inside the servo and multiply and deliver torque to the output shaft.

Will also work for the plastic gears in the BLS251. They are OEM replacements. Same part numbers stamped on them. I used them to replace a broken 1st and 2nd gear in my BLS251.
