  • Piston pin spiral or wire lock ring insertion tool
    Patent number: 7080432
    Abstract: A tool is disclosed, for inserting a multi-turn spiral lock, received by a groove of a piston assembly. The tool includes a handle, for transmitting manual torque forces, to enter a spiral, grooved head, or a profiled fitting, a wire lock ring. The spiral, grooved head, is manufactured, with a ½ turn medium-pitched, helical groove. This permits the ½ spire, after being assembled, to be easily pushed, and transferred, to a piston groove. Also, a wire lock end, equipped with a controlled sliding sleeve, allows the ring to be located on the tool, prior to assembly. This allows for an easy bore insertion to snap the wire lock into the bore groove.
