ABSTRACT:
An improved ratcheting tool swivel body assembly which would include a swivel body having a principal body portion, and a threaded port extending outward from the wall of the stem body, the stem body would further include a continuous opening therethrough, for receiving an elongated stem member, the stem member including a port through the stem member, for allowing fluid to flow between the port and the stem member and the threaded port of the swivel body. The stem member would include a first end having a threaded male end for threadably engaging to the hydraulic fluid source of the torque wrench, and a second end terminating in a hex head portion which is engaged against the upper end of the swivel body. The stem member would be maintained in position through the use of a retainer ring adjacent the lower threaded end of the stem body and rests along a angular surface of the swivel body so that should inordinate pressure be placed on the swivel assembly or it comes into contact with a blunt force, the retainer ring is maintained in position against the angulated surface which prevents disengagement of the stem member from the swivel assembly body.
