S3116 Servo Gear Replacement FUAS3266 Futaba  [FUAS3266]

S3116 Servo Gear Replacement Kit

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

Use this set to replace worn or damaged internal gears, restore proper gear mesh, and reduce gearbox play that affects steering precision or control surfaces. The kit is focused on restorative maintenance rather than performance modification.

Typical installation requires opening the servo case, noting the orientation of existing gears and any shims, swapping the affected gears, checking free play and gear mesh, then reassembling the servo. Verify smooth rotation before reattaching to the linkage or horn.

When servicing, inspect bearings and shaft interfaces for wear and apply a small amount of appropriate servo-safe grease to gear teeth to ensure consistent engagement during break-in.
