This GPM MG214T/0.5M motor gear is an RC-scale pinion intended for motors that match the listed tooth profile. Made from 40Cr steel, the part provides a hardened metal option for compact drivetrains where a 14T pinion is required. The gear uses a 0.5mm module with a motor tooth diameter of 2.2mm and a round motor bore to match standard motor shafts.
Design notes: the pinion has 14 teeth (14T), a module of 0.5mm, and a round-shaped motor hole. It is secured to the motor shaft with two 3x3 set screws, which sit opposite each other for even clamping. Check that your motor's shaft and overall gear mesh fit these dimensions before purchasing, as the part is intended only for motors compatible with these measurements.
Installation and tuning guidance: when fitting the pinion, ensure the gear meshes cleanly with your spur gear and that the set screws are tightened evenly to avoid shaft slippage. For gearing changes, treat this pinion as a direct replacement part for motors that accept a 0.5mm module and 2.2mm motor tooth diameter, keeping adjustments conservative to maintain drivetrain reliability.
