  • Fluid activated connecting pin removal tool
    Patent number: 7562518
    Abstract: A fluid activated connecting pin removal tool, includes a body defining a first cavity adapted to receive a portion of a work piece and a second cavity positioned substantially perpendicular to and intersecting the first cavity. When a fluid activated cylinder is mounted to the body in a first orientation relative to the second cavity, expansion of the fluid activated cylinder results in a piston extending from the cylinder into the first cavity in which the work piece is positioned to exert a force upon a connecting pin connecting portions of the work piece. When the fluid activated cylinder is mounted to the body in a second orientation relative to the second cavity, the secondary cavity serves as a storage compartment for the fluid activated cylinder.
