Update: I was able to get the shell off thanks to this post by Ryan: https://ogrforum.ogaugerr.com/...-photos-and-findings
Unfortunately I took the shell off and came face to face with the main board of the engine sloping down making grease get near the electric boards as well as the worm gear having to bridge a very long gap.
I’m not quite sure what to do; it’s so unfortunate Lionel’s quality control is at such a low standard.
