Futaba S3009 S3010 S3014 S3050 S3070 S3072 S3152 S3305 First Gear Replacement - FU1K24501  [FU1K24501]

Direct replacement first gear for listed Futaba servos

This RC-scale first gear is supplied as a direct replacement for the Futaba servos listed in the model string. Fit it when the original first gear shows wear or stripped teeth, or as part of a gearbox rebuild to recover reliable mechanical engagement within the servo gear train.

Compatibility is restricted to the S3009, S3010, S3014, S3050, S3070, S3072, S3152 and S3305 servo models shown in the product title. Confirm your exact servo model before purchase; the part ships without retail packing and is intended as a direct swap for the first gear inside the gearbox.

Installation notes: disconnect power and controls, remove the servo horn and case screws, note the original gear orientation during disassembly, lift the gear train carefully and replace only the first gear, then reassemble while checking mesh and endplay. Apply a light, application-appropriate grease to gear interfaces and keep lubricants away from the potentiometer and electronics.

Tuning impact: replacing a worn first gear eliminates backlash caused by damaged teeth and helps restore repeatable position control. After installation, perform centering and endpoint checks under the model's typical load.
