Abstract
A high-offset belt tensioner has a base having a pivot tube that defines a first axis of rotation, an arm having a pivot tube-receiving body rotatably seated over the pivot tube and having a pulley pivot tube that defines a second axis of rotation. A torsion spring seated around an exterior surface of the pivot tube-receiving body with a first spring end attached to the base and a second spring end oriented and seated in the pulley pivot tube. A pulley is seated on the pulley pivot tube and rotatable thereabout. The pulley is secured to the pulley pivot tube by a monolithic dust cover clip without the use of a pulley bolt.

A belt tensioner comprising:
- a support base having a pivot tube that defines a first axis of rotation;
- an arm operatively seated over the pivot tube for rotation about the first axis of rotation and having a pulley mount that defines a second axis of rotation;
- a torsion spring has a first end in operative engagement with the support base and a second end in operative engagement with the arm to bias the arm in a belt tensioning direction;
- and
- a pulley having a bearing seated on the pulley pivot tube and rotatable thereabout, wherein the pulley is secured to the pulley pivot tube by a monolithic dust cover clip without the use of a pulley bolt.
