FU1K09301 replacement for Futaba drive gear

This Futaba FU1K09301 first gear is supplied as a direct spare for Futaba servos identified as S3401 and S9404. The part is sold without retail packing and is provided as a single replacement component for model servos.

Typical installation steps include removing the servo horn and case, extracting the worn gear, and fitting the replacement while checking mesh and bearing alignment. Keep track of screws and washers to ensure the original geometry is retained.

Replacing a damaged first gear can eliminate centring errors and intermittent steering behaviour caused by worn teeth, making it a practical part for maintenance and setup work.

Is FU1K09301 an appropriate spare for detailed servo servicing?

It is intended as the first gear spare for Futaba S3401 and S9404 servos and is useful when conducting detailed servicing to restore original gear geometry.

Will the gear arrive boxed or loose in the parcel?

The item is supplied loose without retail packaging, delivered as the single replacement piece.

Any tips for ensuring correct centring after replacement?

After fitting FU1K09301, check that the servo returns to neutral before final screw torque. Fine adjust gear mesh and confirm the output spline aligns with the horn for accurate centring.
