Where is the ideal position to install the tensioner pulley?

[StRafael]

The tensioner pulley should be installed on the slack side near the small sprocket. Additional information: Below is an introduction to the functions of the tensioner pulley: 1. The tensioner pulley serves to adjust the tightness of the timing belt and is typically replaced along with the timing belt, while other components may not necessarily require replacement. 2. The 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 degrees of belt looseness, ensuring a more stable, safe, and reliable transmission system. 3. Over time, belts tend to stretch. Some tensioner pulleys can automatically adjust the belt tension. Additionally, a tensioner pulley makes belt operation smoother, reduces noise, and helps prevent slippage.
