About this First Gear

This item is the direct replacement first gear for the Futaba servo models shown in the title. It ships without retail packaging and is intended as the internal gear used in the primary reduction stage of those servos.

Compatibility applies only to the listed models: S9075, S9157, BLS152, BLS157HV, BLS172SV/HV, and BLS177SV. Do not assume compatibility with other servo codes; confirm the exact model number before purchase.

Fitting tips: power down and remove the servo case before you begin, track the order and orientation of washers and bearings during disassembly, and ensure spline alignment when installing the replacement gear. Once reassembled, check mesh and endplay manually prior to applying power. This component is for maintenance and repair tasks rather than for performance modification.

Will changing this gear affect servo performance?

Replacing a worn or damaged first gear restores original performance but will not increase the servo's rated torque or speed.

How can I confirm my servo model matches the listed compatible parts?

Check the model code printed on the servo housing and compare it with the list in the title. Only order if the codes match exactly.
