A master track chain connection for use on track chains of crawler tractors is disclosed. The master connection includes apparatus for independently securing the track shoe to the split master link thereof and for retaining or clamping the half-links of the split master links together. Separating the track shoe retention function from the half-link clamping function maintains clamping integrity in the event of bolt-loosening as the result of load induced slippage of the track shoe relative the link. The apparatus includes a first bolt threaded into a first threaded aperture for solely fastening the track shoe to the link and a second bolt threaded into a second threaded aperture for solely retaining the half-links together. A third bolt is preferably provided for jointly securing the track shoe to the link and for clamping the half-links together.

A master link for an endless track, comprising: said master link having a mounting surface along one edge thereof for receiving a track shoe, a rail surface along the opposite edge thereof, and a pair of half-links separable along mating interlocking surfaces, said surfaces being oriented in a generally diagonal direction between the mounting surface and the rail surface of the link; and means for independently securing the track shoe to the master link and for retaining said half-links together, said means including at least a first threaded aperture and a second threaded aperture each entering through said track shoe mounting surface, the first of said threaded apertures being adapted to receive a first bolt for solely fastening the track shoe to the link and the second of said apertures being adapted to receive a second bolt for solely retaining the half-links of the master link together, said second bolt having a head positionable in abutting engagement against the mounting surface of the link and not against the track shoe when said track shoe is positioned on said master link.
