ABSTRACT:
An endless track chain is provided with a rotatable sleeve that is mounted about the track bushing to provide the track with longer external bushing life. The rotatable sleeve is sealed and lubricated, as is the standard track joint. However, each is separate from the other with its own supply of lubricant. As a consequence, a failure of a seal for the rotatable sleeve has no effect on the track hinge joint.
