Futaba FUAS3206 Metal Gear Replacement for S3003 Servos - EBS3206 AS3206  [FUAS3206]

Replacing S3003 internal gears

This aftermarket gear set provides metal replacements for the internal gear train of Futaba S3003 servos, enabling repair of stripped or worn components. The parts allow model builders to revive servo performance without replacing the whole unit, focusing on mechanical restoration of the drive train.

Installation notes: remove the servo cover according to S3003 service steps, extract the old gears and install the replacements in the exact same sequence and orientation. Check gear engagement and any axial play prior to closing the case to avoid friction or misalignment.

Performance note: swapping to new metal gears can reduce play and improve positional consistency. After completing the fitment, set the servo to neutral and carry out a full-range bench verification before fitting the servo back into the model chassis.
