What Are the Causes of Engine Belt Wear?

[VanElliot]

Engine belt wear can be attributed to normal wear and tear, structural defects in the timing belt, and improper operation of the tensioner pulley. Normal wear and tear: After several years of use, the timing belt undergoes millions of twists and torsional deformations, making wear inevitable. It should be replaced promptly when it reaches the replacement cycle. Structural defects in the timing belt: Any imperfections on the timing belt, such as small cracks, imperfections in the synthetic material, nicks, or cuts, can lead to premature failure of the belt. When selecting a belt, try to purchase one with fewer defects. Improper operation of the tensioner pulley: The tensioner pulley needs to provide appropriate tension and rotate freely. When it fails to function correctly, like idler pulleys and guide pulleys, it can significantly impact the working life of the timing belt. Pay attention to the working condition of the tensioner pulley and make adjustments in a timely manner.
