Futaba FUAS3185 S136G Servo Replacement Gear Set AS3185 EBS3184  [FUAS3185]

S136G servo replacement gear pack

This RC-scale accessory is a replacement gear set designed for Futaba S136G series servos, supplied with the part references AS3185 and EBS3184. It is offered as a swap option to renew worn or damaged gear trains inside hobby radio control servos.

The purpose of the kit is clear: restore gear engagement, eliminate play from chipped or stripped teeth, and bring servo response back to nominal performance. This entry focuses on compatibility checks, a straightforward installation approach, and how the gear set fits into regular tuning and maintenance for radio control models.

Installation notes: open the servo case and inspect bearings and pinion fit before changing gears, maintain the original gear stack orientation and spacer locations, and confirm smooth end-to-end movement before reinstalling the servo in the model. Standard small hex drivers and a tidy workspace are recommended; no specialized tools are necessary beyond common hobby hand tools.

Maintenance context: replacing degraded gears is a standard drivetrain service that prevents inconsistent steering or throttle inputs caused by internal slop. After fitting new gears, re-centre the servo and check endpoint settings in your transmitter, then test the servo under light load to ensure reliable operation.
