The drive or fan belt, typically, has a V shape, and it has a V-shaped pulley as well. Besides, there are also other appearances, such as wide belts and several small V-grooves arranged, its grooves can be both sides, either top, and bottom, or just one on the bottom.
These belts have the main structure made of small wires covered with rubber. It can bend according to the shape of the pulley and the drive wheels of each type of equipment installed along the belt rotation line.
The belts have limited life equipment, so you should check them regularly. Older belts will begin to develop worn tires, such as cracks on the outer surface or torn sides. Also, there will be an unusual sound alarm when it rotates, for example. The sound of the wind all the time or when starting the engine for a few minutes then disappears.
