Abstract:
A method for enclosing one end of a movable socket within a housing with an expandable cover-plate having a central orifice configured to receive a grease fitting, and simultaneously establishing said central orifice to predetermined dimensions to receive said grease fitting, comprising the steps of:assembling internal components of said movable socket within said housing, with said expandable cover-plate disposed over said internal components; positioning a two-stage assembly tool in axial alignment along a central axis with said expandable cover-plate; exerting a load on said two-stage assembly tool such that a working face of said two-stage assembly tool moves along said central axis to contact said expandable cover-plate, and a concentrically disposed pivot punch extends to seat within said central orifice; increasing said exterted load to axially displace said working face into contact with said housing, displacement of said working face and said pivot punch expanding said expandable cover-plate into conformance with said working face, enclosing said internal components within said housing of said movable socket, and establishing said central orifice to predetermined dimensions corresponding to said pivot punch; and releasing said exerted load to remove said pivot punch from said central orifice and said working face from contact with said movable socket.
