1. First loosen the generator fixing screw and the belt tightness adjustment screw.
2. Then place the generator against the engine so that the distance between the pulleys is the shortest, then place the belt cover on the rocker hammer.
3. Adjust the belt tightness to the appropriate level, tighten the motor mounting screws and adjust the screws.
1. The timing belt becomes loose after being used for a while. When the timing belt cannot fully fit the gear, a loud howling noise occurs when the cold engine starts. If there is an abnormal noise in the belt, we can try to resolve it by adjusting the tensioner or replacing the belt. When the engine runs well, this abnormal noise will disappear automatically. Actually, it's not a major problem. Simply replace the aging timing belt regularly.ur avoid this problem to a large extent.
2. The belt may slip on the generator, causing strong friction and vibration between the belt and pulley, producing a sound of a certain frequency. Apply polyol solution to the surface of the belt and moisturize it thoroughly to reduce hardening and freezing of the belt in winter, thereby maintaining a certain degree of elasticity and reducing slippage. For a new car, one application is enough. If the belt is older, it must be applied continuously for 3 days.
3. The belt drive accessory is affected by other equipment. For example, if the bearing is damaged or stuck, the power of the belt drive accessory will increase and the belt will work excessively. remains in this state for a long time, the power of the belt drive accessory will increase.
4. This may bedue to reduced friction coefficient of the belt surface and excessive belt wear. The owner should check and replace it in time. , the owner can observe one of the groups of transmission belts. If the pointer exceeds the range, it means that the belt has been excessively worn and should be replaced by the car owner in time to avoid more breakdowns during driving and affect driving safety. .
How to judge abnormal belt noise:
You can determine which belt has a problem by listening to the sound. If abnormal belt noise occurs when using the air conditioner, it may be caused by abnormal belt noise. air conditioner compressor. There is a problem with the belt. If there is an abnormal noise when the car is cold, it may be a problem with the engine belt. In this way, the abnormality of the belt can also be judgeded in general.
