Futaba FUAS3219 Servo Gear Replacement for S3103 and S3106  [FUAS3219]

Gear replacement compatible with S3103 and S3106

Supplied as FUAS3219, this gear set is intended for use with Futaba S3103 and S3106 servos and corresponds to the part codes AS3219 and EBS3228 referenced in the listing, provided without retail packaging.

Install this kit when internal gear wear produces slack, uneven movement, or binding; fresh gears return smoother travel and more predictable control response on scale models. Always verify alignment and tooth engagement during reassembly to maintain service life.

The S3103 and S3106 model references indicate intended compatibility; inspect gear profiles and spline dimensions to ensure a correct fit with your servo internals before installation. This item is intended for model servo servicing and workshop replacement tasks.
