Abstract
A method of making a belt tensioner system, in which the system comprises a support unit, an endless transmission belt construction carried by the support unit and arranged to move in an endless path, an arm pivotally mounted to the support unit, a pulley rotatably carried by the arm and being in engagement with the belt construction, and an actuator carried by the support unit and having opposed ends is provided. The actuator has a movable piston projecting out of one of the opposed ends thereof and being in engagement with the arm to pivot the arm in a direction to urge the pulley into the belt construction as the piston is extended outwardly from the one end of the actuator, the other of the opposed ends of the actuator being pivotally mounted to the support unit whereby the actuator pivots relative to the support unit as the piston thereof extends and retracts at the one end thereof.
