Dayco launched a line of heavy-duty serpentine belt kits featuring the company’s two-piece tensioner engineered with an outer and inner tensioner that cuts installation time.
Currently available to order for customers in the U.S. and Canada, there are six part numbers that cover approximately 650,000 vehicle in operation. These kits are specifically designed for Class 8 trucks with Detroit DD13, DD15 or DD16 engines.
In an effort to optimize inventory for distributors and ensure fleet technicians have all the parts needed for a complete belt repair, Dayco’s heavy-duty serpentine belt kits also include two pulleys and two serpentine belts in the appropriate length and width.
“Not only do the kits include all the parts techs need for the job but the two-piece technology cuts the job time in half, getting vehicles in and out of the bays faster,” said Jay Buckley, director of product management for Dayco North America. “Time and again, we learn that the pulley and tensioner weren’t replaced at the same time. Our goal is to call out the benefits of replacing all parts of a front-end accessory drive system at the same time to enhance vehicle performance and service life.”
The tensioner and its pulley counterpart are machined from high strength steel to provide wear resistance under harsh environments. It also features Dayco’s patented flat spring technology and dual pressed-in pulley bearings to provide long bearing life and protection against shock loads.
The two heavy-duty poly-V serpentine belts included in the kit are designed to run cooler, reduce rib cracking and provide increased flexibility. Engineered for high torque and power pulses, Dayco’s belts feature specially treated cords to resist stretching and ensure length stability.
