a clamping device, mounted on the gripping element, configured to releasably secure the gripping element to the shaft; and a force applying element, mounted on the clamping device, the force applying element being configured to allow an extraction force to be applied to the gripping element in a direction parallel to the axis of the shaft. ### Claim 2 (depends on 1) The shaft extraction device of claim 1 wherein the force applying element comprises a slide rod, and the device further comprises a slide hammer slidably mounted on the slide rod. ### Claim 3 (depends on 1) The shaft extraction device of claim 1 wherein the gripping element comprises a pair of hemi-cylindrical elements configured to be positioned on opposite sides of the shaft. ### Claim 4 (depends on 3) The shaft extraction device of claim 3 wherein the hemi-cylindrical elements are lined with an elastomeric material. ### Claim 5 (depends on 4) The shaft extraction device of claim 4 wherein the elastomeric material has a Shore A durometer of about 30 to 85. ### Claim 6 (depends on 3) The shaft extraction device of claim 3 wherein the hemi-cylindrical elements have a length of from about 2 to 6 inches. ### Claim 7 (depends on 1) The shaft extraction device of claim 1 wherein the clamping device comprises locking pliers. ### Claim 8 (depends on 1) The shaft extraction device of claim 1 wherein the clamping device is configured to allow a clamping force applied by the clamping device to be adjustable. ### Claim 9 (depends on 2) The shaft extraction device of claim 2 wherein the slide rod has a length of from about 2 to 3 feet. ### Claim 10 (depends on 1) The shaft extraction device of claim 1 wherein the force applying element has a longitudinal axis that is substantially perpendicular to a longitudinal axis of the clamping device ### Claim 11 (depends on 2) The shaft extraction device of claim 2 further including a slide stop, limiting travel of the slide hammer along the slide rod. ### Claim 12 (depends on 1) The shaft extraction device of claim 1 wherein the clamping device is secured to the gripping device. ### Claim 13 (depends on 12) The shaft extraction device of claim 12 wherein the longitudinal axis of the clamping device is substantially parallel to a longitudinal axis of the gripping device. ### Claim 14 (depends on 12) The shaft extraction device of claim 12 wherein the device is configured so that the extraction force is applied in a direction substantially parallel to the longitudinal axis of the shaft. ### Claim 15 A shaft extraction method comprising: gripping a portion of a shaft having a longitudinal axis with a gripping element; releasably securing the gripping element to the shaft with a clamping element; and applying an extraction force to the gripping element, using a force applying element that is mounted on the clamping device and that has a longitudinal axis that is substantially perpendicular to a longitudinal axis of the clamping device.
