(888) 312-8812 Login SignupGuide the belt through the correct route on a Euro 3 15-liter ISX or QSX engine with the Cummins Engine Timing Belt Idler Pulley. Unlike a driven accessory pulley, the idler redirects the belt and provides a rolling surface that helps maintain the intended path around the engine. A smooth pulley surface lets this idler guide the belt without adding a driven accessory load. Pulley position, diameter, and engine application must agree before installing the Cummins 3680196 so the belt approaches neighboring pulleys at the correct angle.
