Belts and chains stretch or elongate through usage. As belts wear, the initial tension is lessened and will result in slippage and consequently, horsepower loss; unless a form of take-up is used to restore the belt to its original tension. As chains wear, they are elongated and can result in slapping or increased vibration. This shock loading can also result in added bearing wear. Both chain and belt drives , if allowed to run loose will show an increased rate of wear. The Universal Drive Tensioner was designed to operate in all directions, and adjusts easily as tension requirements change. A properly tensioned drive runs smoother and quieter, delivers maximum horsepower, and wears longer.
