Abstract
A replaceable wear cover for track chain bushings which covers and protectively shields the track bushing such that the wear cover, rather than the bushing, directly engages the metallic outer radial portions of the chain-driving sprocket wheel. The wear cover may be made of heat treated steel or like material for long life and includes noise suppression and impact absorbing elastomeric members for reducing noise and impact resulting from driving engagement with the sprocket wheel. A mounting portion of the replaceable wear cover is attached to the inner surface of the track plate by one or more fasteners that pass through the track plate and wear cover mounting portion or by using the same fasteners which attach the track plate to the track links. The wear cover includes a shield portion having depending legs for covering the standard track bushing and which are sprung apart for installation or removal, thereby insuring a tight fit on the bushing.
