Thanks for the manual link, it will come in handy.
The part I'm needing to remove though is the entire top 1/2, the monitor and control areas.

If that comes off I believe I can lay that section on its side and rotate it through the doorway and wheel the base is normally to reassemble in place. Or if it comes apart into 2 pieces for each monitor housing it should walk right through the door.
A quick measurement when I pulled it in the shop yesterday, I believe the total depth is about 40", even with an oversized door that's not going to work without taking it apart.
