Abstract
A machine tread including a first and second pair of plates. The plates have corresponding first ends and second ends, and the second ends of the first pair include outer bores. The first ends of the second pair include aligned bushing bores. The first ends of the second pair fit between the second ends of the first pair, aligning the outer and bushing bores. Ends of a bushing including an inner bore engage the bushing bores forming a pin bore through the inner and outer bores. A retention pin fits in the segmented pin bore. A head end abuts an external surface of the first pair of plates and a locking end extends past the pin bore. A retention cap engages the locking end. A dowel pin fits through a dowel pin bore in the retention cap and the locking end to limit movement of the retention pin.
