ABSTRACT:
A method of installing a seal having a sealing surface in a defined operating position in a rotating machine composed of a stationary part which carries the seal and a rotary part mounted to rotate about an axis of rotation and having a cylindrical surface located to rotate adjacent, and in close proximity, to the sealing surface, which method includes: installing the seal on the stationary part in a position corresponding to the defined operating position so that the seal is immovable relative to the stationary part; machining the sealing surface to a desired final dimension by mounting a machine tool to rotate about the axis of rotation and rotating the tool about that axis; withdrawing the tool; and modifying the installation of the seal so that the seal is supported in the defined operating position so as to be resiliently movable relative to the stationary part.
