Dunno, all my experience is just that, experience, and so I don't know the "proper" names of many parts.
Anyhow, on the opposite side, that shaft fits into a ring of bearings, just like it does on the side you removed, see ?
Now if that ring's popped out on the other side, yeah, you gotta problem, but not really an insurmountable one.
Just a thought.
It's hard to visualise a lot of this without parts-in-hand, so bear with me, guy.
