Litens 642-200-13-70 Drive Belt Tensioner Assembly with Pulley

The Litens 642-200-13-70 is a genuine OEM-quality drive belt tensioner assembly with pulley designed for select Mercedes-Benz vehicles. Litens is the world's largest supplier of original equipment power transmission products, ensuring this tensioner meets exacting factory specifications for form, fit, and function.

Key Features:

• Internal round spring technology provides constant belt tension and alignment throughout its service life
• Heavy-duty steel pulley with close tolerance ball bearing pocket and electro-deposited coating for superior corrosion resistance
• Provides constant, engineered tension and dampening, which maintains correct belt tension and minimizes system vibrations
• Automatic tensioning eliminates the need for manual belt adjustments and prevents belt slip
• Complete assembly includes tensioner mechanism and pulley for direct replacement

Manufactured to meet or exceed original equipment specifications for functionality and durability, this tensioner assembly ensures reliable accessory drive operation. Since accessory drive belts and tensioners are manufactured with similar design life targets, replacing both components together extends system service life and reduces labor costs versus individual replacement.
