How exactly do I service this bottom bracket?
Working on an 89 Schwinn Le Tour, and I took apart the bottom bracket for bearing replacement/lube, and found this...
Any idea how I can replace the bearings in this type of cup?

If you really need new ball bearings, replace the whole thing with a UN unit for $15-$25.

That retainer will just pop out. then service like normal. You can reuse the retainer or not, it wont affect anything. I've seen these on at least 3 different mid to late 80's Schwinns that I have flipped. I think these came prelubed with retainer for easy assembly when new.

If you feel so inclined to replace the BB's once you remove the Hatta retaining ring, just go to your LBS and ask for two (2) # 23 Bottom Bracket Bearings, and drop them in.
If the BB's aren't shot or the spindle isn't worn, just re-lube & install.
