Futaba S3173SVi Servo Housing Set FUEBS3439  [FUEBS3439]

Service housing for S3173SVi servos

This Futaba FUEBS3439 servo case set is made to enclose and shield the S3173SVi servo internals. It replaces cracked or worn shells to re-establish mechanical support and ensure components remain correctly positioned.

Fitment is simple for experienced hobbyists: remove the servo, disassemble per the manufacturer's guidance, transfer the geartrain and circuitry into the replacement case, and reassemble while confirming smooth gear engagement and correct horn fit. Where possible reuse original fastenings and conduct a final check of travel and centring before returning to service.

On the pit or at the field the case makes quick repairs possible, improves the repeatability of servo setup, and gives a robust enclosure that helps maintain calibration during use.
