Futaba FU1K24501 Servo First Gear for S3009 S3010 S3014 S3050 S3070 S3072 S3152 S3305  [FU1K24501]

First gear compatible with specified Futaba servos

This item is an RC-scale replacement first gear intended for the Futaba servo models listed in the title. Use it to replace worn or stripped teeth or as part of a gearbox rebuild to restore reliable engagement of the servo gear train.

Compatibility applies to the S3009, S3010, S3014, S3050, S3070, S3072, S3152 and S3305 servo models as stated in the product title. Confirm your servo model before ordering; the part is supplied without retail packaging and is intended as a direct internal gear swap.

Assembly advice: isolate power and remove the servo horn and enclosure screws, document gear positions during disassembly, remove the gear train carefully and replace the first gear only, then reassemble checking mesh and endplay. Lightly grease gear contact points with a suitable lubricant and avoid contaminating the potentiometer or electronics.

Compatibility notes: fitting a new first gear corrects mechanical play introduced by damaged teeth and helps restore consistent servo positioning. After replacement, perform calibration checks and verify endpoints and centering under normal operating load.
