Abstract: A method of repairing a chain assembly involves aligning bores of inner and outer chain links and inserting a thread end of a pin through the bores. Then, a nut is threadingly engaged with the threads of the pin, the nut is tightened nut on the threads to create an interference fit between the pin and a plate of the outer chain link at the bore of the outer chain link, and the nut is further tightened on the threads until an axial stop blocks further advancement of the nut along the thread end of the pin. Additionally, a kit for repair of a chain assembly system includes a chain link defining a bore, a pin that can form an interference fit with the bore, a nut, and an axial stop that blocks further advancement of the nut along a thread end of the pin when the pin contacts the axial stop.

Abstract: A chain assembly system can include an inner chain link and an outer chain link. The inner chain link and the outer chain link can define a pair of bores. The chain assembly system can include a pin including a head end that defines a head, and a thread end opposite the head end having threads. The chain assembly system can include a nut configured to threadingly engage the threads of the thread end of the pin and an axial stop that is configured to block further advancement of the nut along the thread end of the pin towards the head end of the pin when the pin contacts the axial stop.
