What kind of noise will the tensioner make if it is broken

After the tensioner is damaged, it usually produces an abnormal buzzing or squeaking sound. When the vehicle accelerates, if the tensioner malfunctions, it is often accompanied by a piercing metallic friction sound. The appearance of this sound is due to the inability of the tensioner to effectively adjust the tightness of the synchronous belt or chain, resulting in abnormal working conditions.

The main function of the tensioner is to ensure that the timing belt or chain of the engine is always in the optimal tension state, in order to achieve normal engine operation. As an important component of the tensioner, the tensioning wheel directly contacts the timing belt or chain. Once a malfunction occurs, it not only produces abnormal noise but also seriously affects the normal driving of the vehicle.

There are various symptoms of damage to the tensioner, including engine timing gear jumping, ignition and valve timing disorders, engine shaking, and ignition difficulties. In severe cases, it may even result in the vehicle being unable to start. At the same time, damage to the tensioner may also cause increased fuel consumption, insufficient power, detonation and other malfunctions, which can damage the overall performance of the vehicle.

Therefore, maintenance and upkeep of the tensioner are very important. It is generally recommended to inspect and replace the tensioner and tensioning wheel when driving a vehicle for about 50000 kilometers. When replacing, it is usually necessary to synchronously replace the synchronous belt or chain to ensure the normal operation of the entire system.

For a scooter, the symptom of a damaged tensioner may manifest as a loose transmission chain. When the tensioner fails, the transmission chain will become loose and unable to work together with the transmission wheel, resulting in friction, jamming, and other phenomena when moving or cycling. This not only affects the driving experience, but may also cause further damage to the vehicle.

In summary, as an important component of the engine timing system, the tensioner's normal operation is crucial for the vehicle's performance and stability. Once a malfunction or abnormal noise is found in the tensioner, it should be checked and repaired in a timely manner to avoid causing greater damage to the vehicle.
