Typically the way these things work is, there is a piece of
cast iron that piece is milled to seat the bearings. Into
this goes the arbor. In order to change one or the other
the same procedure has to be performed. In other words, the
arbor shaft is removed first followed by the bearings.
Since it appears that you won't be using these pieces again
(?) I'd say you could probably tap them all out with a stout
piece of dowel and a hammer. As for replacing, I'd take all
the parts and pieces to your local Delta Service Center and
see if they'd press them for a nominal fee. Or, you could
hunt down a friend who has a press. Or, you could buy a
press.

In other words, you really should have them pressed back in.
Too many chances to wreck the thing if you don't.

I took mine to the Delta Service Center.
