What are the symptoms of a broken car balance shaft?

[LaAugust]

After the balance shaft is broken, the engine vibration will significantly increase, affecting the comfort of driving and riding. Here is some information about the balance shaft: Dual balance shafts: This type of balance shaft uses a chain drive to rotate two balance shafts, which is more expensive and occupies more space, commonly used in large-displacement motorcycles. One of the balance shafts rotates at the same speed as the engine, eliminating vibrations at the same frequency as the engine. The other balance shaft rotates at twice the engine speed, eliminating the second-order vibrations of the engine. Single balance shaft: This type of balance shaft operates using a gear drive mechanism, which is simpler in structure and occupies relatively less space, widely used in single-cylinder and small-displacement engines.
