FUAS3184 Gear Set — Product Summary

This entry lists the FUAS3184 aftermarket gear set for Futaba servos, noted in some references as AS3184 or EBS3180. The kit is offered without original packing and is aimed at hobbyists performing servo maintenance or rebuilds.

The parts are intended only for the model codes named: S135, S3501, S3502, S9002 and S9601. If you service those specific Futaba servo models, these gears allow replacement of internal components while retaining the existing gear train geometry.

Service guidance: document the existing gear positions before removal, handle the PCB and bearings with care to prevent damage, and ensure each replacement gear is seated in the same orientation. After putting the servo back together, test for smooth operation and correct neutral before returning to normal use.

Buyer note: this is a gear-only listing without original packing. Verify your servo model numbers match the compatibility list and inspect gear mesh carefully during installation to confirm proper engagement.
