Futaba FUAS3267 Replacement Gear Set for S3153 Servo  [FUAS3267]

Service Replacement for S3153 Servos

This Futaba FUAS3267 gear set fits S3153 servos and provides a direct replacement to restore precise steering and control in hobby radio-controlled models. The article focuses on fit, serviceability, and how fresh gears support repeatable steering inputs on scale models.

Compatibility is limited to S3153 servos as specified by the product name, so verify your servo model before purchasing. The gear set replaces worn or damaged gears to restore mechanical engagement and reduce play that can affect precision during operation.

Installation is straightforward for anyone comfortable with small electronics work: remove the servo horn and case screws, note the orientation of the gear stack as you disassemble, swap the worn gears with the replacement set, and reassemble while checking mesh and endplay. Use light, appropriate grease on gear teeth and avoid over-tightening case screws to prevent binding.

Tuning role: installing a correct-fit gear set helps maintain consistent steering centering and reduces backlash. This supports finer endpoint adjustments and smoother feedback when trimming or programming endpoints and rates in your transmitter.

Maintenance tips: inspect gears periodically for chips or excessive wear, keep the gear train free from grit, and use small amounts of suitable gear grease when reassembling. If you encounter unusual noise or binding after replacement, recheck gear orientation and bearing alignment.
