ABSTRACT:
A portable disassembly tool is provided to disassemble a track link assembly from a machine by removing opposed track links from the track link assembly. The portable disassembly tool includes first and second members that are tightly secured to the track link to be removed by a plurality of fasteners. The second member has clearance holes therein to freely receive the ends of the associated track pin assemblies. A third member having spacer members extending therefrom is disposed adjacent to the second member with the spacer members extending into the respective clearance holes into contact with the ends of the track pin assemblies and secured to the second member by a second plurality of fasteners. By alternately tightening the plurality of fasteners, the track link is pulled from the associated track pin assemblies. During the removal of the track link, binding in any direction is overcome.
