An assembly technique and device for enclosing an open end of a movable socket (10) comprised of fully hardened materials with an expanding cover-plate (66) and for positioning the cover-plate at a predetermined distance from an exposed pressure plate (62) of the movable socket so as to provide a reliable indicator of socket wear. During assembly, various internal components of the movable socket, including the pressure plate, are installed within a housing (12) through a posterior opening (16) with the cover-plate is positioned over the components. A two-stage ram (100) having first and second contact surfaces (142, 167) is brought into engagement with the cover-plate. Pressure exerted by the two-stage ram is transferred to the cover-plate through the first surface, expanding the cover-plate into a generally planar configuration and enclosing the internal components within the socket housing. A continued increase in pressure extends the second contact surface into engagement with the cover-plate, further deforming the cover-plate to a predetermined final position relative to an internal component for a consistent indication of wear on the socket components within the housing. |
