Abstract
A tool for removing a retaining pin from a tooth of a ground engaging tool assembly of the type in which the tooth has side walls defining a socket which receives a shank of a mounting member, and in which the retaining pin impales aligned holes in the tooth side walls and in a through bore of the shank and is secured by a split washer that is held in a cavity surrounding an end of the through bore and engages a circumferential groove in the pin. The tool includes a mounting element that embraces the tooth to align a stud with the pin, and force multiplying means for moving the stud effectively axially to slide the pin endwise out of engagement with the washer.
