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 is 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. A dust cover is
seated on the pulley pivot tube juxtaposed to the pulley and a first end of
the pivot tube is deformed toward the dust cover to retain the pulley without
the use of a pulley bolt.
