First Gear for Futaba Servos (S3009 S3010 S3014 S3050 S3070 S3072 S3152 S3305) - FU1K24501  [FU1K24501]

Precision first gear for the listed Futaba servo models

This is a replacement first gear intended for use inside the Futaba servos shown in the product title. Replace the part when teeth are damaged or during a tune-up to recover consistent mechanical engagement across the gearbox.

The gear is compatible with S3009, S3010, S3014, S3050, S3070, S3072, S3152 and S3305 servo models as listed. Confirm your servo model before purchase; the item is supplied without retail packaging and is intended to be installed as the gearbox's first gear.

Fitment tips: remove power, take off the servo horn and case screws, keep track of gear orientation as you disassemble, carefully lift and swap the first gear only, then reassemble checking mesh and endplay. Apply a light, appropriate lubricant to gear interfaces and keep grease away from the potentiometer and circuitry.

Tuning benefits: installing a fresh first gear reduces backlash and improves repeatability of position commands, which helps when fine-tuning servo endpoints and response. After installation, run calibration and verify centering under typical load conditions.
