ABSTRACT:
Hydraulic pliers useful for mounting and dismounting snap rings (otherwise called C-shaped stop rings) of large nominal diameter. They comprise a hand-holdable plier main body having working fluid contained therein, a hydraulic piston mechanism contained in the plier main body and adapted to be moved by hydraulic forces exerted by manual pumping operation effected by gripping action applied from outside, and a working-pin opening and closing mechanism mounted on a plier head for operative connection to the hydraulic piston and adapted to be opened or closed in the same plane and at right angles to the directon of movement of the hydraulic piston as the latter advances. The hydraulic pliers do not require any accessory equipment and are handy to carry. Thus, they are designed to expand or contract snap rings of large diameter lightly and efficiently by their hydraulic force.
