The LCN Door Closer Hold Open Head And Tube 3048 - 3048L.  As the arm rotates the pivot point threads close on to the mounting bracket face and create a friction catch.  If yours is new, try rotating the mounting plate 180 degrees so the threads tighten as it closes. This replacement part from LCN either breaks or wears out.   The material some times wears out due to the friction of open and closing.  But the biggest issue seems to be the point where the tube mounts to the cast iron connector.
