open end timing belt

The failure of a timing belt can lead to extensive engine damages, often causing what is known as catastrophic failure. When the timing belt breaks, the engine can fall out of synchronization, potentially leading to the pistons striking the valves. This situation can result in bent valves, damaged pistons, and a host of costly repairs. To avoid this, most manufacturers provide a recommended timeline or mileage interval for replacing the timing belt, generally ranging from 60,000 to 100,000 miles.

The performance of Poly V belts is heavily dependent on the materials used in their construction. Generally, Poly V belts are made from a combination of high-quality synthetic rubber compounds, polyester, and sometimes even aramid fibers. The rubber components provide flexibility and durability, allowing the belts to bend and flex around pulleys without strain. Polyester cords enhance strength and tensile stability, ensuring that the belts can withstand high loads and resist elongation over time. In high-performance applications, aramid fibers may be incorporated for their exceptional strength-to-weight ratio and resistance to wear and tear.
