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

Gear set for Futaba S136G servos

This item is a replacement gear pack intended for Futaba S136G servos and is provided with part identifiers AS3185 and EBS3184. It serves as a direct replacement for damaged or fatigued internal gears in hobby radio control servos.

Functionally, the kit restores proper meshing, reduces slop from missing or chipped teeth, and returns the servo to expected mechanical performance. The description emphasises fitment, a practical installation method, and routine service considerations for radio control models.

Installation guidance: carefully remove the case, inspect bushes and the pinion for wear, keep the original gear order and spacer positions, and ensure the gear train moves freely before sealing the case. Typical hobby tools—small hex drivers and tweezers—are usually sufficient for the job.

Service notes: renewing worn gears is part of standard drivetrain upkeep and helps avoid erratic steering or throttle responses. Once fitted, check servo centering, adjust endpoints on your transmitter, and perform a slow-load test to validate smooth operation.
