Replacement S3116 Servo Gears FUAS3266 Futaba  [FUAS3266]

S3116 Gear Set Overview

This gear set serves as a direct replacement referenced as AS3266 and EBS3336 for the S3116 servo platform. It is provided without packing and intended for model-scale radio control use only.

Install these gears to correct worn gear engagement, recover accurate gear mesh, and reduce gearbox play that can compromise steering response or control surface accuracy. The kit targets repair and restoration rather than performance enhancement.

Procedure typically requires opening the servo housing, recording the positions and any shims, installing the replacement gears, checking mesh and free play, then reassembling the unit. Ensure the output spline turns freely before reconnecting the linkage.

During servicing, examine bearing seats and shaft condition for signs of wear and apply a light smear of compatible servo grease to the teeth to maintain consistent engagement through running-in.
