ABSTRACT:
A seal removal tool includes a hollow cylindrical member, an advancing device, and a extracting device. The cylindrical member has an open, circular first end with a barbed knife-edge that has a perimeter with a diameter substantially equal to an inside diameter of an inner circular edge of an annular seal fitting snuggly around an exposed end of a shaft. A second end of the cylindrical member is partially closed with an enlarged threaded opening therein. The advancing device comprises a first threaded elongated rod element and a pressing portion for pressing against the partially closed second end. The extracting device comprises a second threaded elongated rod element having an enlarged tip for engaging the exposed end of the shaft after disengaging the advancing device. The enlarged tip is configured to screw into an enlarged threaded opening in the cylindrical member and to advance axially and press against the exposed end of the shaft as the second threaded elongated rod element is rotated.
