The only things holding the drive motor mechanism secure are two rails, one along each side. You can see those rails in this image: they appear as black rails on each side of the drive.
Once you get the mechansim off those rails, it pivots easily, still held by two springs in the front and two cables attached to the mainboard. One is a white cable seen in the top left hand corner, the other a tiny ribbon cable seen in the bottom left corner.
