1 Answers
When replacing the belt, it is necessary to replace the tensioner pulley. Here is an extended introduction about the tensioner pulley: 1. Structure: The tensioner pulley mainly consists of a fixed housing, tension arm, wheel body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the different tightness of the belt, ensuring the stability, safety, and reliability of the transmission system. 2. Function: The tensioner pulley is a wearable part in automotive components. Over time, belts tend to stretch. Some tensioner pulleys can automatically adjust the belt tension. Additionally, with a tensioner pulley, the belt operates more smoothly, reduces noise, and prevents slipping. The function of the tensioner pulley also includes adjusting the tightness of the timing belt.
