Kyosho UM323C 23T Steel Motor Pinion for 1/48  [KY-UM323C]

23T Steel Motor Pinion for 1/48 Micro Cars

This Kyosho UM323C steel pinion is an RC drivetrain part with 23 teeth sized for 1/48 scale installations. As the motor pinion it transfers torque from the motor to the spur gear, so correct mesh and alignment are important to keep power delivery smooth and reduce premature wear.

Fit this pinion for routine replacement or when changing final drive ratios on small electric micro or compact touring chassis. Before installation confirm the motor shaft diameter and the pinion fastening method on your motor, then set a small clearance when meshing to avoid binding. Secure the pinion and spin the drivetrain at low throttle to check engagement.

Maintenance is simple: check teeth for nicks or burrs, clear debris, and replace the pinion if wear degrades mesh quality. For quieter operation inspect the spur gear and bearings rather than altering the pinion finish.
