Futaba FUSG28G Replacement Gear Set for S28G Servos  [FUSG28G]

Direct-fit replacement gears for service

This Futaba FUSG28G servo gear set is an RC-scale replacement gear pack intended for use with S28G-series servos. The text highlights practical fitment notes, installation steps, and how the gear pack restores servo movement after gear wear.

Use this gear set when a servo exhibits grinding, play, or lost positional accuracy due to worn gears. The set is intended for hobby-grade servos and should be used during routine maintenance or repair of model cars, boats, or aircraft servos that specify S28G compatibility.

Installation requires careful disassembly of the servo case, inspection of bearings and other drivetrain parts, and reassembly with correct gear mesh and endplay. Keep small parts organized (use labeled trays or a magnetic mat), note the order of shims and washers, and avoid forcing gears to prevent stripping.

After installation, verify smooth rotation through the full travel and check for binding under load. Use your transmitter trims and servo endpoints to confirm restored centring and travel limits before reintroducing the servo to a model in active use.
