  • Patent number: 10213824
    Abstract: A tool for removing a swaged fastener from a piece of equipment tubing includes, in combination with a slide hammer component, a multiple segment fastener that can be manually rotated between respective stations. The segments, around a central base, include: (a) a large hollow collar station for hammer-sliding back an innermost locking nut of the swaged fastener; (b) a large rounded-slit station for reverse-hammer sliding off an outermost ferrule of the swaged fastener; (c) an elongated tube station sized to fit over and abut a front end of the equipment tubing for hammer-sliding to push back its innermost ferrule; and (d) a small, rounded-slit station for positioning behind the pushed back innermost ferrule and reverse hammer-slide it off of the equipment tubing. A related method is also disclosed.
