ABSTRACT:
The pivot or hinge joints of a track chain assembly of a track laying tractor each include lubricant cavities which are sealed by a pair of spaced apart seals. The seals each include a resilient rubber load member and a relatively rigid polyurethane seal member having an annular sealing lip which is biased into place by the load member when the seal is installed. The effectiveness of the seals is tested by adding a coloring agent or dye to the lubricant in the cavities being sealed, by operating the assembled chain in a mud box for a predetermined time, by disassembling the chain and then by inspecting the seal members to see whether or not surfaces thereof normally outside the sealed cavity have been contacted by leaking lubricant as evidenced by the presence of the dye.
