ABSTRACT:
A retaining ring installation tool for use in installing retaining rings onto shafts and into bores is formed from a single piece of metal to define a cylindrical, elongated body. A hollow cavity is formed in one end of the body and the wall of the body that defines the cavity is slotted to form a plurality of individual, flexible spring contact arms or fingers which extend forwardly from a rear body portion and which collectively define an insertion end of the tool. The ends of the fingers are enlarged to ensure contact occurs between the tool and the retaining ring during the installation of the ring onto a shaft or into a bore. The contact arms are bent either radially inwardly or outwardly so that they will contact the retaining ring at all times during installation of the ring.
