The flange (82), the first shaft (84), and the second shaft (86) at least partially define a leak path (LP). The leak path (LP) includes a radial gap (212) between the first shaft (84) and the second shaft (86); and a leak channel (154) in an axial surface (156) of at least one of the first shaft (84) or the second shaft (86).
