Futaba S9102 Internal Gear Set - FUAS3198 (AS3198 EBS3092)  [FUAS3198]

Overview of FUAS3198 Replacement Gears

The Futaba FUAS3198 gear set is specified for the S9102 servo line and is referenced by AS3198 and EBS3092. It ships without retail packing and is intended as internal replacement gears rather than a full servo assembly.

Use this set to renew worn gear teeth, recover from stripped gears after incidents, or refresh a servo during a service teardown. As this is a parts-level item, double-check your servo model before dismantling the unit.

Installation advice: follow the manufacturer's service steps to open the casing, keep small parts and bearings in sequence, and inspect gear mesh and endplay on reassembly. Apply modest gear grease and test the servo through its complete travel. When in doubt, consult a qualified hobby technician or Futaba S9102 service literature.
