CSC Pug Speedometer Drive Gear for CSC Pug Scooters and 139QMB Bikes
This replacement drive gear is made for CSC Pug scooters and compatible 139QMB Chinese motorcycles. It handles a key job in your scooter's speedometer system. You can also browse our range of scooter speedometers and gauges for related options.
Construction and Function
The gear mounts on the axle, so it sits securely inside the speedometer system. Its precise design passes speed data from the wheel through to the gauge. It is manufactured to match the vehicle's original specifications, so it works as a dependable stand-in for the factory part.
When to Replace Your Drive Gear
Consider swapping the drive gear if your speedometer stops working properly or displays speeds that seem off. Worn or damaged teeth can compromise both how the gauge performs and your safety on the road. Checking the part periodically and replacing it when needed helps keep the speedometer reading correctly.
