Futaba FUEBS3372 BLS153/BLS651 Gear Kit for Servo Maintenance  [FUEBS3372]

Service gear kit for Futaba BLS153 & BLS651

This gear kit serves as a like-for-like replacement for Futaba BLS153 and BLS651 servo internals, aimed at hobbyists maintaining or repairing their servos. Fit it when gear wear affects precision or creates slack in control linkages.

Standard workshop procedure applies: detach the servo horn, open the case, document the gear stack order, swap out the worn gears with the supplied parts and reassemble. Use the correct screwdriver for the case screws, and keep washers and spacers in their original positions to keep mesh and neutral alignment accurate. Photographing each step helps if you are less experienced.

Functionally this kit is a maintenance part rather than an upgrade; it returns the mechanical drivetrain to reliable operation so steering and control responses remain consistent. After refit, test travel and center position, then fine tune the horn if necessary.
