Swing Axel Removal

Hi Yall,

I've got a swing axel box laying around and it's taking up too much space.

Last night I tried to take it apart but had difficulty removing the gearbox side plates.

I'm not familiar with these things so how do I pull the bastard apart? Do I need some sort of puller to avoid damaging the gearbox casing by prying the bits apart.

Thanks in advance.
