Futaba FUAS3184 Servo Gear Set for S135 S3501 S3502 S9002 S9601 replacement gear set  [FUAS3184]

Futaba Servo Gear Replacement Overview

This is an aftermarket replacement gear set listed as FUAS3184 for Futaba servos, referenced also with AS3184 and EBS3180 in the product title. It is offered without original packing and intended for RC-scale servo maintenance and rebuilds.

Compatibility is limited to the model codes shown in the product name: S135, S3501, S3502, S9002 and S9601. If you maintain or rebuild those servo models, this set is provided to replace worn or damaged internal gears while preserving the original gear train layout.

Typical installation considerations: open the servo case with the appropriate hex driver, document the original gear order and orientation, remove the electronic components carefully to avoid damage to the PCB and bearings, then swap in the replacement gears following the original sequence. After reassembly, check for smooth rotation and correct neutral position before reattaching to the linkage.

Notes on use: this listing is for the gear set only, sold without packing. Confirm model numbers match your servo before purchase and inspect gear engagement and mesh during reassembly rather than assuming fit from model name alone.
