Abstract
The adjustment mechanism of the present invention is mounted to a frame and comprises an alignment cam that is pivotally mounted to the frame by a tension link pivot pin. The alignment cam is provided with an actuating arm that is coupled to a longitudinally extendible adjusting member. The longitudinally extendible adjusting member comprising a screw jack. A tension link is pivotally mounted to the tension link pivot pin. Camming surfaces on the alignment cam are skewed with respect to the transverse axis defined by the tension link pivot pin so that rotation of the alignment cam twists the tension link and thereby the idler wheel predominately about a vertical axis. Albeit to a lesser degree, rotation of the alignment cam also twists the tension link and idler about a longitudinally extending horizontal axis. Therefore by extending or retracting the screw jack, the toe-in/toe-out orientation of the idler wheel can be adjusted.
