ABSTRACT:
A pressing tool for securing screw connections of steering linkages of motor vehicles particularly between a ball joint socket having a tubular extension and a threaded pin of a pitman arm which has two diametrically opposite parallel wrench flats which are positioned within a tubular extension of the ball joint socket. A tubular extension comprises a sleeve arranged over the ball joint socket and it has two diametrically opposed longitudinally extending slots each having a double arm lever pivotally mounted therein. The double arm lever includes a first arm portion providing a jaw oriented radially inwardly and an opposite arm portion having a camming surface. A control member is located in the sleeve adjacent the camming surface of each lever and it is mounted so as to be threadably movable axially to run along the camming surface and pivot the lever. The lever arm which has the jaw is moved by the control member to engage and deform a deformable cylindrical portion carried by the ball joint socket so that the deformed portions engage against the flats so that the pitman arm with turn with the rotation of the ball joint socket member.
