ABSTRACT:
A tool for removing a faucet stem and cartridge from a faucet body; the stem of the type having a threaded outer end; the cartridge of the type having a central bore retaining the stem; the bore including an inward facing ledge. A cylindrical standoff sleeve has an inner end for bearing against the faucet body. A rod passes through the standoff sleeve. The rod has, on its very inner end, threads for engaging the stem threads and, above that, a device for engaging a cartridge inward facing ledge. Rod outer end includes a threaded section. A rotatable handle threads on the rod outer end and bears against the standoff sleeve outer end such that rotation of the handle moves the rod axially relative to the standoff sleeve for extracting the stem and cartridge after engagement. The cartridge extraction device is an irregular, substantially planar washer mounted on the rod such that the washer may rotate between an insertion position wherein the plane of the washer is non-normal to the cartridge bore axis such that the washer fits inside the bore and an ledge engaging position wherein the plane of the washer is normal to the cartridge bore axis. A washer insertion sleeve moves on the rod and includes on its inner end a magnet for biasing the washer in the insertion position.
