An extractor tool (200) for removing and replacing a plumbing fixture such as a leaking, rusted tub shoe flange with or without cross hairs, includes a shaft (210) having left-handed threads (218) over most of its length and a frusto-conical wedge (212) near one end terminating in a plurality of axial lugs (214) forming a castle around an axial recess (216), the other end of the shaft being flatted to receive a wrench. A plurality of separate, arcuate shaped, shoes (232, 234, 236) are slidably positioned around the threaded portion of the shaft and are maintained there by a flexible o-ring (244) forming an expandable body having a central bore portion and at least the inner end adjacent the frusto-conical wedge of the shaft formed with a tapered circular recess (240). A washer (246) and nut (248) are assembled on the shaft from the threaded end. |
