As shown below:
The generator belt of this model needs to drive the vehicle's generator and compressor. It is driven by the crankshaft of the engine. There is an idler gear between the generator and compressor. , the function is to give belt pressure to the generator and compressor pulleys, and there is an idler pulley on the top, which has the same function. The tensioner on the crankshaft pulley is an automatic tensioner, which generates a belt pressure in real time according to the engine belt operation, allowing the belt to maintain the most accurate tension.
Notes on the generator belt:
1. The grooved side of the pulley must match the groove of the belt, so as to ensure that the belt Will not come off the pulley.
2. The plane side of the pulley should correspond to the plane side of the idler pulley and the tension pulley to avoid excessive wear of the belt.
3. When replacing the belt, it is best to replace the tensioner at the same time.
4. The belt should be checked frequently for cracks, and if so, it should be replaced.
