Service gear for Futaba BLS351

This first-stage gear is provided as a spare part for Futaba BLS351 servos commonly used in RC models, and is intended to reinstate proper gear engagement when the original gear shows wear or damage. It is an OEM-compatible spare to help maintain servo function and reliability in scale applications.

Fitting the part requires opening the servo housing, removing the gear train, and replacing the first gear while preserving the positions of bearings and spacers. Reassemble carefully, check alignment of the output spline and servo horn, and make sure the gear runs freely before powering up to avoid binding.

In maintenance and tuning workflows the first gear affects backlash and mesh; installing a new first-stage gear can eliminate excessive play and improve control precision. Once fitted, verify neutral and run a few low-load cycles to ensure the servo operates smoothly.

How should I install the replacement first-stage gear?

Open the servo case, carefully remove the gear stack while recording the order and spacer positions, swap in the new first-stage gear in the same orientation, then reassemble and confirm correct mesh and neutral before normal use.

Will fitting a new first gear extend servo life?

Replacing a worn first gear can reduce wear on adjacent gears and restore accurate engagement, which helps extend overall servo longevity when combined with correct assembly and lubrication.

Can I reuse the bearings and spacers during replacement?

Preserve the original bearings and spacers if they are in good condition; inspect them for wear or damage and replace if necessary to maintain proper gear spacing and function.
