As shown below:
The generator belt of this model should drive the vehicle's generator and compressor. It is driven by the engine crankshaft. There is an intermediate 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. It generates real-time belt pressure based on engine belt operation, so that the belt maintains the most precise tension.
Generator belt notes:
1. The grooved side of the pulley must match the groove of the belt, to ensure that the belt will not come loose from the pulley.
2. The flat side of the pulley must match the flat side of the idler pulley and the tensioner pulley to avoid wearExcessive belt wear.
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.
