Litens 950434A Accessory Drive Belt Tensioner Assembly

The Litens 950434A Accessory Drive Belt Tensioner Assembly delivers original equipment quality for demanding accessory drive applications. As the original equipment supplier for Volkswagen, Litens manufactures this tensioner to meet all OE form, fit, and function specifications, ensuring reliable performance and precise fitment.

Key Features:

• Hydraulic tensioning shaft technology for consistent, automatic belt tension adjustment
• European-style split steel pulley design for enhanced durability and efficiency
• Torsion spring design (round spring) for superior alignment and longevity
• Automatically compensates for belt stretch and wear over time
• Made in Germany with OE-exact engineering standards
• Installation instructions included for professional-grade installation

This tensioner plays a critical role in maintaining proper accessory drive belt tension, preventing belt slippage, reducing engine noise, and ensuring consistent performance of alternators, air conditioning compressors, and other belt-driven accessories. The robust hydraulic design provides superior damping characteristics compared to conventional spring-loaded tensioners, extending both belt and component service life.

Important: For optimal performance and longevity, verify that the alternator overrunning clutch pulley is functioning properly before installation, as a failed one-way clutch can cause premature tensioner failure.
