Abstract
A method is provided for assembling a structure of an aircraft powerplant. This method includes mounting a seal runner onto a rotor using an installation tool, the installation tool including an inner locating surface and an outer locating surface, the inner locating surface axially recessed from and radially inboard of the outer locating surface. The mounting of the seal runner includes axially pressing a runner mount onto the rotor by moving the installation tool axially towards the rotor, with the outer locating surface axially pressed against a distal end of the seal runner, until the inner locating surface axially engages the distal end of the rotor. After the seal runner is mounted onto the rotor using the installation tool, the runner mount is attached to the rotor through a radial interference fit between the runner mount and the rotor and the runner mount is axially disengaged from the rotor.
