<p>Track links have been typically difficult to service due to their size, weight, and the considerable use of press or force fits between components. According to the present invention, there is provided an easily serviceable hinge joint including two meshed hinge members having aligned bores therein. The track assembly includes two meshed track links (10, 12) one having a narrow end (20) received in a notch (22) in an enlarged end (24) in the other, aligned bores (26, 28) in the links, a hinge pin (30) received in the bore for pivoting the links together, annular grooves (40) at opposite ends of the pins, retaining rings (44) in the grooves, recesses (42) in one of the links about the bore therein adjacent the ends of the pin and defining shoulders substantially abutted by the retaining rings, and caps (50, 52) closing the recesses and having axial portions (54) about the periphery of the respective retaining rings for preventing radial movement thereof.</p> |
