1 Answers
The service life of tensioner pulleys and idler pulleys is approximately 80,000 kilometers, and they should also be replaced when abnormal noises occur. Below is an introduction to tensioner pulleys: Introduction: A tensioner pulley mainly consists of a fixed housing, tension arm, pulley body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the varying tightness of the belt, ensuring the stability, safety, and reliability of the transmission system. Construction: Tensioners are categorized based on their location into accessory tensioner pulleys (such as alternator belt tensioner pulleys, air conditioning belt tensioner pulleys, supercharger belt tensioner pulleys, etc.) and timing belt tensioner pulleys.
