S136G Gear Replacement FUAS3185 AS3185 EBS3184 Compatible with Futaba  [FUAS3185]

Service kit: gears for S136G Futaba servos

This product is a replacement gear pack for the Futaba S136G servo family and is supplied with the part identifiers AS3185 and EBS3184. It is presented as a direct option to renew damaged or worn gear sets inside hobby radio control servos.

The kit's function is to reinstate proper gear mesh, remove excess play from worn teeth, and return the servo to predictable mechanical operation. This description concentrates on compatibility notes, a reliable installation routine, and how the parts fit into standard tuning and servicing workflows.

Installation advice: strip the servo case and inspect the pinion and bushes for wear before replacing gears, maintain the original gear order and spacer placement, and confirm the gear train moves freely without binding prior to reassembly. Typical small hex drivers and fine hand tools suffice for the task.

Tuning and verification: replacing compromised gears is an effective preventative measure against erratic steering or throttle response due to internal backlash. After refitting, check servo neutral and endpoint values in the transmitter and conduct a low-speed load test to verify smooth behaviour.
