ABSTRACT:
In a pre-mounted tensioning device the fastening bolt is covered by the idler wheel. The fastening bolt is serviced through a recess provided in the wheel surface. A pre-mounted unit is created through the insertion of a fastening bolt whose head is pushed by spring elements against the wheel surface, thus preventing the idler wheel from turning and forcing the recess to coincide with the fastening bolt.
