Dayco Heavy Duty Idler Pulley

Dayco Heavy Duty Idler Pulleys, also sold as idler/tensioner pulleys, replace worn pulleys on serpentine accessory drives in heavy-duty diesel engines. They are engineered for the demanding drive systems of Class 4-8 commercial trucks. Each pulley helps keep the belt aligned and the accessory drive running smoothly.

Key Features:

• Durable construction: Machined from high-strength steel or powdered metal for wear resistance in harsh environments.
• Dual pressed-in bearings: Support long bearing life and protect against the shock loads common in diesel truck applications.
• Engineered design: Computer-aided design (CAD) and finite element analysis (FEA) help deliver structural integrity, which minimizes vibration and helps extend belt life.
• OE-quality standard: Built to meet or exceed original equipment quality for consistent belt tracking and performance.

Dayco is a long-established name in belts, tensioners and pulleys. Heavy-duty operators and mechanics specify these pulleys because they are built to hold up in over-the-road and off-road work. Select the child item that matches your application to get the right pulley for your drive.
