Dayco ela (elastic) or stretch belts are specifically designed for two, three, and four point drives that are designed to use self-tensioning belts. Although these belts may look like standard poly rib belts, they are very different. These specially designed elastic belts have self-tensioning capabilities required by specific OE drives. Vehicles that are manufactured with stretch belts must replace them with stretch belts. These belts are not interchangeable with standard constructed belts of their same size. Dayco ela belts utilize a proprietary EPDM construction that is designed to elongate over the fixed pulley system, and then maintain the required belt tension over the life of the belt. The backbone behind the Dayco ela belt is its specially developed polyamide tensile member, which allows for high elongation required for installation, yet provides the proper tension maintenance properties to transmit the accessory loads demanded for the drive. This belt construction incorporates a wear resistant EPDM rib material, along with a highly elastic EPDM cushion rubber that surrounds the polyamide tensile cord, thus providing the required adhesion and flexibility to maintain lasting performance. Stretch belts have unique installation instructions depending on the OE application. Installation may require a specialized tool for the application or a simple zip tie. Do not attempt to install by prying the belt on the pulleys. Dayco provides detailed instructions on the reverse side of the sleeve.
