Abstract
Abstract An equalizer bar is mounted on a track roller frame bearing by a split cap arrangement. The split is angled relative to a transverse axis of the vehicle, so that fastening means may be easily reached sidewardly of the track frame to disconnect the equalizer bar from such bearing means. In one preferred embodiment the equalizer bar main body, to which the cap is removably secured, overlies and is in contact with the bearing means to provide that, upon removal of the cap, the equalizer bar rests on the track roller frame.
