This GPM aftermarket motor pinion is built as a direct scale accessory for AXIAL SCX6 models, providing a 15-tooth pinion intended for small RC motors that match the listed shaft and pitch details. The part is made from high carbon steel to improve wear resistance compared with typical stock alloys, and it functions as the interface between the motor shaft and the drivetrain to transfer torque to the gearbox.
The design details provided by the source note a 5mm centre hole and a 1mm tooth pitch, information you should confirm against your motor shaft and existing pinion before installation. Use common RC practices: check mesh with the spur gear, secure the pinion to the motor shaft using the supplied fastener, and verify free rotation before powering the model.
