ABSTRACT:
A track joint is provided with a controlled running clearance by means of a controlled interstice producing membrane placed between the opposing axial thrust surfaces of the joint. The membrane is of a substance which sacrifically self-destructs upon the initial pivotal movements of the joint. The purpose of the membrane is to relieve the joint of compressive loads which become locked in the joint during its assembly and can cause galling of the thrust surfaces and injury to track seals in the joint.
