ABSTRACT:
A kit for permitting the mounting and removal of spiral lock washers to and from an annular washer retaining groove on a tumbler wheel post of a combination lock or the like includes a cylindrical tubular container-tool with an internal chamber for storing a washer removing tool and a washer guide stub. The guide stub is fittable in an axial opening in an end of the tumbler wheel post so that such a spiral lock washer positioned on a conical downwardly and outwardly flairing surface of the stub can be moved into the washer retaining groove by positioning the open end of the container-tool over the washer and then forcing the washer downwardly along the guide stub into the retaining groove; the washer removing tool has a cylindrical body having one end insertable in the axial opening in the post with a spring urged pivot arm mounted in the body having an outer end adjacent the body for movement between the flights of a washer in the washer retaining groove so that subsequent rotation of the body effects movement of the washer from the groove upwardly and outwardly of the post.
