Futaba FUAS3188 Internal Gear Set - compatible with S3002 and S3016 Servos  [FUAS3188]

Internal gear replacement for S3002 and S3016

The FUAS3188 gear set is supplied as a replacement parts kit for Futaba S3002 and S3016 servos, marked AS3188 and EBS3190. This listing supplies the internal gear components without original external packaging and is intended for parts-level repair to restore mechanical engagement.

Compatibility is limited to the Futaba S3002 and S3016 model references shown; verify the AS3188 or EBS3190 identifiers on your existing gears before disassembly. Typical servicing steps include opening the servo case, recording shim and gear order, removing the damaged gears, and fitting the replacement set in the same sequence.

After installing, confirm correct gear mesh and endplay with the output spline and horn connected, then run the servo at low speed to ensure smooth rotation and to check for any binding or unusual noise. These checks confirm the replacement gears are performing correctly in RC use.

This product is offered as the gear components only; no extra accessories or original retail packing are included. Use the AS3188 and EBS3190 part markings to match this kit to your servo.
