Futaba FUAS3215 Replacement Gear Set for S9602 Servos  [FUAS3215]

S9602 metal replacement gears by Futaba model FUAS3215

This aftermarket gear pack carries Futaba model FUAS3215 and the markings AS3215 EBS3226, and is intended for installation in S9602-class servos. It provides a replacement path for stripped or fatigued internal gears, restoring proper tooth engagement and reducing play when installed with correct mesh.

Compatibility: specified for S9602 servos as reflected in the product title; always double-check spline count and servo case clearance before fitting. Installing the set requires careful servo teardown, correct gear orientation, and reassembly to retain accurate gear mesh and horn centring.

Role in tuning: fitting metal internals raises gear stiffness and longevity, which can alter control feedback and better resist stripping under heavy load. After swapping, verify pinion alignment and run the servo through its full travel unloaded to confirm smooth operation.

Use this gear set to replace degraded components in S9602 servos, apply recommended lubrication sparingly during reassembly, and confirm free movement before reinstalling in your radio model.
