Abstract
A wheel balancer for balancing a wheel having a rim and tire. The wheel balancer comprises a chassis and a driven shaft extending away from the chassis for rotating the wheel. An A&D arm, pivotal and axially extendible with respect to the chassis, is also provided. A first laser device is operable to produce a laser spot at a desired weight placement location on an inner surface of the rim. The first laser device is manipulable by an operator to move the laser spot to the desired weight placement location. A second laser device is attached to the A&D arm and movable therewith. The second laser device produces a visible marker on the inner surface of the rim for determining when the A&D arm is in a plane of the desired weight placement location.
