Detailed Description

Dayco 5080622 is an accessory drive serpentine belt engineered for engines that require an 8-rib, K-section belt with a 1.10-inch top width. The EPDM rubber compound is paired with aramid reinforcement to help maintain belt integrity under heat, cold, and continuous accessory loading. This belt is specified for heavy-duty and industrial applications, including Cummins, Freightliner, Volvo, John Deere, and Komatsu equipment that call for the listed dimensions and rib count. If you are replacing a worn serpentine belt on a Cummins-powered truck or a Volvo application, matching the part number and dimensions is essential for proper fitment.

This part cross-references Gates K080623 for the same application.

What It Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing belt
• Loss of accessory drive consistency from belt stretch or fatigue
• Incorrect belt length or rib count during replacement
• Heat-related belt deterioration in demanding operating conditions

Installation Notes and Tips

Verify the belt routing, rib count, and measured dimensions before installation. Confirm that the application calls for an 8-rib K-section belt with a 62.21-inch effective length and 62.76-inch outside circumference. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, and replace any damaged components that could affect belt tracking. For vehicle-specific service, confirm the application against the OEM reference for your Cummins, Freightliner, Volvo, John Deere, or Komatsu model.
