swirl frame flange (1), so that the clamp nut is at 9
Place inletfairing (4) onto torque tube mount
(6). Leave inlet fairing loose.
While inlet fairing (4) is loose on
torque tube mount (6) during
installation, it must be held in
place by hand to prevent damage
(3) With second mechanic helping to keep parts in
proper position, secure inlet fairing (4) and torque tube
