All brands of replacement automatic belt tensioners are not alike. Automatic tensioners that are specifically designed for the unique packaging & operating conditions of each engine & accessory belt layout configuration (‘application specific’) are recommended & highly preferred. When properly designed & applied, these belt tensioners will provide pre-determined (‘engineered’), constant tension & variable damping to the belt. The engineered output of these tensioners consistently maintain correct belt tension and help to dampen belt system vibrations, within the belt's replacement life.

The primary advantages of a well-designed automatic belt tensioner are:

• Maintains its correct alignment to the belt

• Automatically maintains correct accessory belt tension

• Automatically dampens normal accessory system vibrations

• Eliminates need to adjust / re-tension belts

• Prevents belt slip (noise / excessive belt wear)

• Optimizes life of belt

• Provides for indication of correct belt length

• Provides indication of excessive belt stretch (replacement)

• Improves belt system alignment

• Extends accessory system component life

Litens accessory drive tensioners provide:

• Equal or greater than Original Equipment quality and performance

• Custom, application-specific fit, form and function

• Quieter and smoother accessory drive operation

• Extended accessory drive component durability

• Constant ‘engineered’ belt tension

• Improved belt life

Are all automatic accessory drive belt tensioner designs equal?

Original Equipment manufacturers subject their parts to rigorous development testing and performance validation. Whenever the design of a replacement part is compromised from the Original Equipment fit and specification, reduced performance and durability can often result. Litens is the established global leader in Original Equipment automatic belt tensioner design technology and market coverage.

Litens’ unparalleled belt tensioner design and applications experience is now brought to the North American replacement market exclusively by Tendeco Sales Inc.
