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.

Claims (12)

1. A fluid activated connecting pin removal tool, comprising:

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;

means for mounting a fluid activated cylinder to the body in a first orientation relative to the second cavity such that, upon expansion of the fluid activated cylinder, a piston extends 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; and

means for mounting the fluid activated cylinder to the body in a second orientation relative to the second cavity such that the second cavity serves as a storage compartment for the fluid activated cylinder.

2. The fluid activated connecting pin removal tool as defined in claim 1 , wherein the fluid activated cylinder has a mounting flange and the body has a receiver adapted to engage the mounting flange in either the first orientation or the second orientation.

3. The fluid activated connecting pin removal tool as defined in claim 2 , wherein the mounting flange is rectangular and the receiver has opposed channels adapted to receive the mounting flange, the opposed channels having a longitudinal axis, the mounting flange having first bolt receiving apertures perpendicular to the longitudinal axis of the fluid activated cylinder, the body having second bolt receiving apertures extending perpendicular to the longitudinal axis of the opposed channels, the mounting flange of the fluid activated cylinder being secured to the receiver of the body in both the first orientation and the second orientation by sliding the mounting flange into the opposed channels and extending bolts through the second bolt receiving apertures of the body and into the first bolt receiving apertures of the mounting flange.

4. The fluid activated connecting pin removal tool as defined in claim 1 , wherein the body has a first end, a second end, and opposed walls that extend between the first end and the second end, the first cavity extending transversely through the opposed walls at the second end, the second cavity extending longitudinally between the opposed walls.

5. A fluid activated connecting pin removal tool, comprising:

a body having a first end, a second end, and opposed walls that extend between the first end and the second end, a first cavity adapted to receive a portion of a work piece extending transversely through the opposed walls at the second end and a second cavity positioned substantially perpendicular to and intersecting the first cavity extending longitudinally between the opposed walls;

a fluid activated cylinder having a longitudinal axis and mounting flange positioned transversely to the longitudinal axis;

a receiver positioned at the first end of the body and adapted to engage the mounting flange of the fluid activated cylinder in either a first orientation or a second orientation relative to the second cavity, in the first orientation, upon expansion of the fluid activated cylinder, a piston extends 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, and in the second orientation the second cavity serves as a storage compartment for the fluid activated cylinder.

6. The fluid activated connecting pin removal tool as defined in claim 5 , wherein the mounting flange is rectangular and the receiver has opposed channels adapted to receive the mounting flange, the opposed channels having a longitudinal axis, the mounting flange having first bolt receiving apertures perpendicular to the longitudinal axis of the fluid activated cylinder, the body having second bolt receiving apertures extending perpendicular to the longitudinal axis of the opposed channels, the mounting flange of the fluid activated cylinder being secured to the receiver of the body in both the first orientation and the second orientation by sliding the mounting flange into the opposed channels and extending bolts through the second bolt receiving apertures of the body and into the first bolt receiving apertures of the mounting flange.
