Abstract
A method and apparatus of assembling a joint of an endless track chain for track-type vehicles to prevent end play in the joint is disclosed. The joint includes a pair of links and a cylindrical pin. Each link includes a laterally outwardly offset outboard end collar having a boss extending outwardly therefrom and a bore therethrough. Each boss has an outer periphery and the pin includes opposite end portions. Each end portion is pressed and non-rotatably mounted into a respective one of the bores of the outboard end collars. The method comprises the steps of forming a generally arcuately shaped annular groove about each of the end portions of the pin, placing a punch device against the outer periphery of the boss in radial alignment with the groove in the end portion of the pin, and applying a sufficient force on the punch device to form at least one mechanically formed nodule protruding from the second bore of each outboard end collar into a respective one of the grooves. The nodule has a cross-sectional configuration substantially conforming to the groove.
