Product Details

Gates Timing Belt Pulley T42230 is an engine timing belt idler pulley for Mitsubishi Eclipse, Galant, Lancer, and Outlander applications. It is built with a smooth backside running surface, which is used where the timing belt rides on the back of the pulley rather than on a grooved sprocket surface. The steel body and flanged design support stable belt routing in timing systems that rely on precise alignment.

The Gates PowerGrip idler pulley line includes fixed idlers and replacement pulleys for tensioner bracket applications, giving this part line a focused role in timing belt service. This part cross-references GMB 448-6050 for the same application.
