Dayco Idler Tensioner Pulley 89015 – Serpentine & V-Belt Replacement

PRODUCT OVERVIEW

The Dayco Idler Tensioner Pulley 89015 is engineered as a direct replacement for serpentine and V-belt drive idler and tensioner pulleys. It is designed to maintain proper belt tension, reduce vibration and support long belt life in modern engine drive systems.

KEY FEATURES

• No Slack design for consistent belt tension and stable operation.
• Suitable for serpentine and V-belt drive systems.
• Smooth running surfaces help minimise belt noise and vibration.

CONSTRUCTION & PERFORMANCE

This pulley uses specially formulated glass-filled polymer for high strength, cooler running and improved wear resistance compared with standard plastic pulleys. Advanced 3D CAD design and finite element analysis are employed to optimise structural integrity for both plastic and steel variants.

• Glass-filled polymer construction for durability and heat resistance.
• Precision-machined surfaces and tight tolerances for reduced vibration.
• Helps extend belt service life in demanding operating conditions.

BEARING TECHNOLOGY

The Dayco 89015 pulley incorporates lifetime lubricated ball bearings with double high-temperature seals. This bearing arrangement is critical to overall pulley service life and ensures reliable performance under thermal and mechanical load.

• Lifetime lubricated ball bearings for long-term reliability.
• Double high-temperature seals for protection against contamination.
• Optimised for continuous operation in engine bay environments.
