Dayco Automatic Belt Tensioner Assembly (MPN: 89236)

Engineered for optimal performance and durability in serpentine belt systems.

The Dayco Automatic Belt Tensioner Assembly is designed to maintain consistent tension on serpentine belt drives, which are essential for powering various engine accessories. Utilizing an original flat spring design, this tensioner minimizes variations in tension, thereby reducing the risk of premature accessory bearing failure and enhancing overall performance. The innovative construction includes a PTFE strip within the spring to resist abrasion, while the flat spring is coated to prevent rust, ensuring longevity and reliability.

This assembly features a heavy-duty cast aluminum spring case and arm, providing additional strength and resistance to cracking and fatigue. The design incorporates a steel pivot tube where necessary, which enhances strength for critical torque requirements. Additionally, the lubricated nylon pivot tube bushing and spring bushing contribute to quieter operation, while the thermoplastic rubber spring slot plug helps keep contaminants at bay.

With a focus on durability, the Dayco Automatic Belt Tensioner Assembly includes a rubber O-ring that seals against dust and grime, and a zinc-coated mounting bolt that resists rust. This assembly is compatible with OEM specifications, making it a reliable choice for maintaining the efficiency of serpentine belt systems.
