Abstract
A crawler track mechanism including a plurality of track plates each mounted on track chain links, the chain links being interconnected by bushes having an outer sleeve rotatably journalled on an inner sleeve which in turn is rotatably journalled on a central cylindrical pin). A drive sprocket, and if necessary an idler sprocket, includes recesses having a semi-circular cross section to receivably locate the bushes. The bushes, by virtue of the relative rotation between the pin, the inner sleeve and the outer sleeve, reduce friction and wear between the drive sprocket and the chain bushes.
