2. Loose or offset: Check the position of crankshaft pulley. If it is found to be loose or offset, it may be caused by loose bolts or worn hub. This will lead to belt relaxation and affect the transmission effect, so it is necessary to replace the crankshaft pulley.
3. Belt wear: Observe the belt on the crankshaft pulley. If obvious wear, crack or fracture are found, it means that the crankshaft pulley has reached or approached its life limit and needs to be replaced in time.
4. Unstable speed: When the engine is running, if the speed is unstable or there is obvious jitter, it may be a problem with the crankshaft pulley, such as unbalanced hub or uneven wear, which needs to be replaced.
5. Engine fault light is on: If the engine fault light is on, accompanied by performance degradation or other abnormal symptoms, it may be that the crankshaft pulley is faulty and needs to be inspected and replaced.
Generally speaking, the crankshaft pulley is the key component of the normal operation of the engine. Once the above-mentioned signal appears, it indicates that there is a problem with the crankshaft pulley and it needs to be replaced in time to ensure the normal operation of the engine and the effective operation of the transmission system. If it is necessary to replace the crankshaft pulley, it is recommended to seek the help of professional technicians to ensure the correct replacement operation and improve safety. It is very important to observe and identify the signal that the crankshaft pulley needs to be replaced in time for maintaining the normal operation of the engine and prolonging the service life of the crankshaft pulley.
