What are the effects of a bad tensioner pulley?
1 Answers
The effects of a bad tensioner pulley are: 1. Increased engine noise during sudden acceleration; 2. Engine timing misalignment; 3. Disordered ignition and valve timing; 4. Engine vibration and difficulty in ignition. The tensioner pulley is a belt tensioning device used in the automotive transmission system, mainly composed of a fixed housing, tensioning arm, wheel body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the varying tightness of the belt, ensuring the transmission system remains stable, safe, and reliable. The tensioner pulley is a wear-prone part of the vehicle and needs to be replaced promptly when damaged, along with checking whether the belt has cracks or deformations.
