Accessory Drive Tensioners
Upgrade Your Engine's Performance with Accessory Drive Tensioners
If you want to upgrade your engine's performance and keep it running smoothly, you need to make sure that all the components in your accessory drive system are working together in perfect harmony. This is where accessory drive tensioners come in. These small but mighty devices are responsible for keeping your belts tight, reducing vibration and friction losses, and optimizing overall efficiency.
The History and Classification of Accessory Drive Tensioners
The first accessory drive tensioners were introduced in the early 1980s as part of a new wave of engine technologies aimed at improving fuel efficiency and reducing emissions. Over the years, they have evolved into a wide range of designs and configurations to meet the specific needs of different engines and applications. Common types of tensioners include flat-wire spring tensioners, round spring tensioners, and hydraulic tensioners.
The Advantages of EP Accessory Drive Tensioners
At EP, we specialize in providing high-quality, durable, and efficient accessory drive tensioners that are designed to work seamlessly with our belts, dampers, decouplers, and other components. Our tensioners feature a unique flat-wire spring design that provides a wider operating range and less tension variation than traditional spring designs. This reduces the risk of premature accessory bearing failure due to high tension and lessens the risk of belt noise, slippage, and poor performance caused by low tension as the belt stretches and wears out over time.
Installation, Maintenance, and Repair
Installing an accessory drive tensioner is a relatively straightforward process that can usually be completed in just a few minutes. Simply follow the manufacturer's instructions to remove the old tensioner and install the new one. As with any engine component, it's important to perform regular maintenance to keep your tensioner in top condition. Check the tension and condition of your belts, pulleys, and tensioners at least once a year or as recommended by your vehicle manufacturer. If you notice any signs of wear or damage, make sure to replace the component as soon as possible to prevent more serious problems down the road.
