A V-belt is an element that is used to transfer power from the engine or transmission to the accessory or device. V-belts are most often used to drive an alternator, a coolant pump or a compressor, and in agriculture, belts are used in agricultural devices and accessories operating at high rotational speeds. V-belts are the most frequently worn parts of agricultural machines due to the material they are made of and damage resulting from overloads during machine operation. A worn V-belt should be replaced with a new one as soon as possible to prevent an accident or damage to the machine. A poorly installed V-belt or incorrectly set tensioner, too little or too much tension on the V-belt may result in faster wear. The first signs of V-belt wear (e.g. belt stretching) are a loss of machine power or an unnatural sound when the device is operating.
