So after unscrewing everything, theres two pieces of plastic glued down behind the tabs, it might be possible to heat it up and pull them out but I'm not entirely sure.
From my experience I found it easiest to just cut the plastic around the tabs on the chassis and then pop up the tabs and the plastic glued behind it with a tiny flathead screwdriver to break the old glue.
Not ideal if you want to keep it pristine but if you're not worried about the resale value it's not the worst thing in the world.
I've got images up on the drive unit doc on how the internal gear assembly works and it can be found under clam-shells.
