Abstract
High-offset belt tensioners have a base, an arm having a first end operatively rotatable relative to the base and having an axially offset second end defining a pulley mount, a torsion spring operatively connected to the arm and the base to bias the arm in a belt engaging direction, a pulley rotatably mounted to the pulley mount, and a bolt or bolt sleeve that has axially oriented splines or knurls fixing the pulley to the pulley mount. The bolt or bolt sleeve are non-rotatable relative to the pulley mount and are configured to engage a tool to load the high-offset tensioner during installation.
