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