Blue Bird Commercial Bus Belts and Hoses

Designed to replace idler and tensioner pulleys for serpentine drives in heavy-duty diesel engine applications, Dayco HD idler/tensioner pulleys are machined from high-strength steel or powdered metal material to provide excellent wear resistance under ha

Product Features:

• Engineered for the demanding drive systems of today’s class 4-8 heavy-duty commercial trucks
• Premium OE technology to ensure peak performance under extreme conditions
• Utilizes 3D dimensional computer aided design (CAD) and finite element analysis (FEA) for optimal design and maximum structural integrity
• Meets or exceeds OE quality

Produced for heavy-duty vehicles and buses with multiple accessories, Dayco HD poly-V belts are made from EPDM material to resist heat and are compliant with the latest standards, guaranteeing resistance, reliability, low noise and longer service life. En

Product Features:

• Engineered to handle operating conditions with temperatures up to 130°C (266°F)
• Designed for multiple accessories such as A/C, power steering pumps, alternators and water pumps
• Capable of delivering excellent performance in high torque and high power pulse applications
• Specially formulated treated cord insures length and tension stability on heavy duty diesel engine drives for the life of the belt

The Dayco banded narrow raw edge V-belt is recommended for industrial applications where space, weight and power capacity are critical. It features a stronger PET polyester cord design for improved performance and offers high stability, low tension decay, improved durability and reduced maintenance. The banded narrow raw edge V-belt’s cog profile is engineered to improve cooling effects and bending fatigue as well as provide extra flexibility for smaller pulleys. This raw edge classical design features EPDM rubber for more advanced abrasion, heat and oil resistance at wider temperature ranges and increased power capacity vs. wrapped belts.

Product Features:

• Advanced protection against abrasion, heat and oil
• Perfect for textile mills, fans, lathes, grinding machines, compressors and pumps
• Special cord design enhances performance and durability

For heavy duty diesel engine accessory drive applications, Dayco’s HD automatic belt tensioner is designed to handle higher torque and power pulses. The heavy-duty cast aluminum body and pulley arms translate into extra strength and durability and the patented flat spring design prevents fluctuations to the tensioner body as its footprint doesn’t change when it’s under tension. This reduces the risk of belt noise and also helps avoid separation of the housing a key failure seen from competitive products. Dayco automatic belt tensioner H.D. also includes rugged pulleys with dual lifetime lubricated bearings to deliver long lasting, dependable service. Feature highly damped designs using a wave spring and a metal ring with a bonded polymeric surface that acts as a radial shock absorber for the tensioner arm while reducing contamination.

Product Features:

• Designed to prevent fluctuations to the tensioner body for longer service life.
• Reduces the risk of noise and helps avoid housing separation
• Includes pulleys with lubricated bearings for longer lasting performance
