Abstract

A method is provided for assembling a structure (20) of an aircraft powerplant. This method includes mounting a seal runner (32) onto a rotor (30) using an installation tool (108), the installation tool (108) including an inner locating surface (118) and an outer locating surface (120), the inner locating surface (118) axially recessed from and radially inboard of the outer locating surface (120). The mounting of the seal runner (32) includes axially pressing a runner mount (72) onto the rotor (30) by moving the installation tool (108) axially towards the rotor (30), with the outer locating surface (120) axially pressed against a distal end (68) of the seal runner (32), until the inner locating surface (118) axially engages the distal end (46) of the rotor (30). After the seal runner (32) is mounted onto the rotor (30) using the installation tool (108), the runner mount (72) is attached to the rotor (30) through a radial interference fit between the runner mount (72) and the rotor (30) and the runner mount (72) is axially disengaged from the rotor (30)°.
