Abstract: A belt tensioner for an engine accessory drive is installed over a pulley such that rollers extend toward the engine. Due the belt being between the tensioner and the engine, installation of the belt on the pulley is difficult. To simplify installation, a removable belt guide is included in the belt tensioner. Two methods of installing the belt and tensioner are envisioned. In a first method, the belt is first installed on the pulley and the belt guide holds the belt toward the pulley radially as the tensioner is installed over the pulley. In a second method, the belt is first installed to the tensioner and the guide holds the belt radially away from the pulley as the tensioner is installed over the pulley. In both methods, the belt guide is removed after the belt and tensioner are installed.
