ABSTRACT:
A tool for installing and removing snap rings (40) of the type which includes a pliers-like implement (10) whose jaws (12b,14b) are separated when handgrip members (12a,14a) are urged together, includes a narrow projection (36) mounted on one jaw (12b) for extending into a snap-ring hole (38) on one side of a snap-ring break (46), and a slot (42) on the other jaw (14b) into which a break edge (44) of the snap ring (40), on the other side of the break (46), fits. The narrow projection (36) is angled away from the opposite jaw (14b) and the slot (42) is narrower at one end than the other. The pliers-like implement (10) basically includes two arms (12,14) each forming a handgrip and a jaw, a circular-shaped fulcrum member (16) about which the two arms (12,14) pivot, and at least one circular spring (18,20) for biasing the two arms (13,14) together on the fulcrum member (16) and for preventing the fulcrum member (16) from migrating away from its desired fulcrum position.
