Abstract
A belt tensioner is disclosed that has a spring case defining a receptacle for a torsion spring and having an arm extending radially outward and axially rearward therefrom and terminating with a bore configured for fastening the spring case directly to an engine. The belt tensioner has a support base non-rotationally connected to the spring case through a pivot tube. The pivot tube defines a first axis of rotation, and a pulley mount of the support base defines a second axis of rotation. The support base includes at least one fastener bore for connection to the engine. An arm is coupled to the support base for rotation about the first axis in response to a spring force applied by a torsion spring seated within the spring case and has a free end that defines a pulley mount that defines a third axis of rotation.
