Description
V-belt - original spare part GY6 743x20x30mm, 125/150cc (152QMI).
The 4-stroke cylinder GY6 is one of the most widespread engines for two-wheelers, for which there are of course numerous original spare parts.
The choice of the right V-belt is enormously important for the optimal transmission of the driving force. Only through the perfect interaction of variator, converter, clutch and V-belt can best acceleration values be achieved.
When to change the V-belt?
On scooters, the engine power is transmitted to the rear wheel via the V-belt or drive belt, which connects the CVT variator to the torque drive. As a rule, it should be replaced every 10,000 to 20,000 km. The belt slips when it is heavily worn. By the way, a new belt also slips and needs a short run-in period.
How to change the drive belt?
Replacing the V-belt is a relatively easy, you don't need advanced technical know-how. The first step is to remove the variator cover to get to the variator. You'll need a piston stopper and a blocking tool to remove the CVT and clutch bell. You can then remove the worn V-belt and replace it with the new one. When reassembling, make sure that the V-belt is properly seated and has the correct tension.
