This GPM SCX6017TS motor pinion is an RC-scale replacement pinion designed for pinion-to-motor applications on compatible electric crawlers and rock bouncers. It is made from high carbon steel to improve durability compared with typical stock brass or softer alloys, and it is intended to transfer motor torque to the drivetrain without implying any real vehicle use.
The pinion features 17 teeth with a 1mm pitch and a center bore sized for 5mm motor shafts as supplied in the original data. Use it where a 17T, 1mm-pitch pinion is required to maintain correct mesh with your spur gear and to match the motor shaft diameter. The part includes the small screw shaft accessory for securing the pinion to the motor where applicable.
Installation notes: confirm the motor shaft diameter is 5mm before fitting, check gear mesh with the spur gear to avoid excessive backlash or binding, and secure the set screw to the manufacturer's torque recommendation for your motor setup. Routine inspection of gear wear is recommended for durability and consistent performance.
