Graphitic packing removal tool
Graphitic packing removal tools are described for removal of the seal rings in one piece from valves and pumps. The packing removal tool has a cylindrical base ring the same size as the packing ring with a surface finish, perforations, knurling or threads for adhesion to the seal ring. Elongated leg shanks are mounted axially along the circumferential center. A slit or slits permit insertion around shafts. A removal tool follower stabilizes the upper portion of the legs to allow a spanner wrench to be used for insertion and removal

Installation and assembly device and method of using
The present invention relates to an installation and assembly device and method for facilitating the fitup of mating components during blind or remote installation and assembly, especially where close fitup tolerances are involved. The present invention is particularly useful for the purpose of facilitating vertical and/or radial relative positioning of a pump impeller within a mating inlet nozzle during a blind assembly wherein actual fitup cannot be observed during installation. The information within identifies just one successful application of the installation and assembly alignment device for a pump. The device, however, is not solely limited to pump assembly but can be used in other cases where fitup of a sleeve inside a mating bore is required under conditions of close tolerance during a blind or remote assembly. The device is likewise not limited to circular configurations but can be used for many other shapes or configurations. Any material that can be machined and hold reasonably close tolerances can be used for the device. Also, because the sleeve position is adjusted by set screws or bolts, the concentricity can be radially biased, if required, to achieve particular alignment conditions
