[en] The major modification to the D0 detector for the next physics collider run is the upgrade of the central tracking system. The first component to be installed will be the solenoid magnet, with the central pre-shower attached. This engineering note is directed to the installation of the solenoid magnet and the equipment needed to accomplish this task. As part of the installation process, the main detector must undergo a change in position of one of its major components, namely the South End Calorimeter (SEC). This calorimeter must be completely decoupled from the main detector, i.e. all cabling and cryo lines removed. The equipment used for installing all calorimeters (bridge and support structures) will be put into position and the calorimeter (SEC) will be pulled off of the detector center beam and parked on the south sidewalk of the D0 Assembly Hall. The necessary cryo lines will re-connected in order to keep the cryostat cold. This calorimeter will remain here during the greater portion of the upgrade reconfiguration schedule. When this task is finished, the old central tracking system and its mounts will be removed from the bore of the Central Calorimeter (CC). The main detector is now ready to receive the new tracking system, starting with the solenoid magnet.
