Please be very careful when reconnecting everything on the AOS. It is easy to dislodge other things because the space is so cramped and with cold weather/gloves it is worse.
The AOS is a part I would carry with me on a longer trip because it could be an issue getting a replacement. Some special tools may also help like Mayhew pliers:
