S9202/S9304/S9403 Replacement Servo Housing FUAS3091 AS3091 EBS3096 Futaba  [FUAS3091]

Overview of the Case Set

The Futaba FUAS3091 case set serves as a replacement housing for S9202, S9304 and S9403 servo models named in the product title. It highlights fitment considerations and practical uses for maintenance and tuning on radio-controlled cars and boats.

Items are supplied as the case set only without original packing; they act as like-for-like replacement bodies for the listed servo assemblies. Always check the servo model stamp on your unit matches S9202, S9304 or S9403 before starting work to guarantee compatibility.

When installing, first power down the transmitter and remove the servo from the model. Keep alignment marks visible and transfer original bearings or shims where applicable. These housings are intended to contain your existing internals and not to change gear ratios or the electronics.

A new case can recover mounting points and horn alignment after impact or fatigue, helping steering response remain consistent and making reassembly easier. Verify center and end points after reassembly and perform a bench test prior to refitting in the model.
