Wheelhorse 520-HC Tranny/Transaxle Separation?

[steddy 0]

I have a mid 1980's 520-HC that I'm working on separating the rear end from the hydro pump. Besides the 4 bolts that I've removed, what holds that assembly together? I think it is the Eaton pump. Everything I find online says they should pretty much just pop apart. I don't want to break anything, but I'm getting pretty close to snapping, here. It just doesn't seem like it should be that difficult.

Thnx
