Belt TENSIONERS

Each belt tensioner consists of an idler pulley on the end of a spring loaded pivot arm. The pivot arms can be turned manually for removal and installation of the drive belts.

Each belt tensioners is calibrated to automatically maintain the correct tension of the related drive belt.

The belt tensioner also provides the means to remove and install the drive belt. When the belt tensioner is rotated with a wrench against its spring to the end-stop, two holes align between the arm and the case that allow the tensioner to be pinned in the "install" position. The pin should only be removed when using the wrench to back the tensioner off. Pulling the pin without using a wrench can damage the tensioner itself and/or the belt.
