What Causes the Timing Chain of MG5 to Jump Teeth?

[AlejandroLee]

The reason for the timing chain of MG5 jumping teeth: Due to overload or improper design and manufacturing, the phenomenon where the flexible gear teeth slip out of the rigid gear teeth during meshing. Jump teeth phenomenon: During the use of the toothed belt, its tension will decrease due to wear. If the tension of the toothed belt is not adjusted in time, the phenomenon of the toothed belt jumping teeth will occur. Therefore, to ensure the normal operation of the engine, the tension of the toothed belt should be checked and adjusted regularly. The interval for inspection and adjustment should be determined based on the road conditions and climate conditions the vehicle is driven in. Function: The main function of the engine timing belt is to drive the engine's valve train, ensuring that the intake and exhaust valves open or close at the appropriate time, allowing the engine cylinders to intake and exhaust normally. In some models, such as the Volkswagen Jetta (EFI), Santana 2000, Bora, Audi, etc., the timing belt also takes on the task of driving the water pump.
