Futaba S136G Replacement Gear Set FUAS3185 AS3185 EBS3184  [FUAS3185]

Replacement gears for S136G units

This accessory is a gear replacement pack for Futaba S136G servos and includes the part references AS3185 and EBS3184. It is intended to replace fatigued or damaged gears inside hobby radio control servos.

The set's role is to restore correct gear engagement, remove play caused by worn teeth, and return the servo to expected mechanical feel. The overview covers fitment considerations, basic swap procedures, and how this kit supports regular tuning and upkeep of RC models.

Fitment tips: remove the servo shell and examine internal bushes and the pinion before installing new gears, replicate the original gear stack order and any spacers, and check for smooth travel through the full range before mounting the servo back into the vehicle. Standard hobby drivers and a neat working area are adequate.

Practical maintenance: replacing worn gear components is a routine service task that prevents unpredictable control inputs from internal slop. After installation, re-centre the servo, fine-tune endpoints on your transmitter, and run a controlled load test to confirm reliable operation.
