Cassette oscillating
Took my cassette off to clean, and re-installed. Now the gears seem to shift side to side when I spin it. Is that normal?

No, is the lock ring on straight?

It isnt normal.
something is loose. Maybe a spacer is missing, maybe the lock ring isnt tight enough, not sure what. But no the cassette shouldn't wobble.

I think you have a freewheel and that would be normal as a Freewheel is a self contained unit and the quality of freewheels varies. If it is indeed a cassette that slides onto a freehub body then you might want to make sure you are using the thin spacer that goes on the freehub before the cassette.

Depending on what cassette and hub you have you may need a spacer or two behind the cassette. Happened to me twice when I first went to 10 speed and took me hundreds of miles to even notice.

OP mentioned cassette, and he responded about the lock ring, so I'm guessing it's a cassette, but we'll have to wait and see.

Looking at the hub, the stepped design of the center part of the hub is very characteristic of early Shimano freehubs/cassettes.
So, I'd bet a 99% chance it is actually a cassette.
It wouldn't hurt to take the cassette off and verify that nothing is bent, or out of place, but I wouldn't be particularly concerned with a minor wobble either.
How does the axle turn?

As mentioned above, freewheels tend to wobble like that with no ill effects. Perhaps even improving shifting. So, if there aren't other symptoms (wheel out of true, stiff axle, issues with coasting, etc), then perhaps don't need to worry about it.

FYI: If this is a 7-speed hub, it does not need any spacers behind the cassette.

Hyperglide teeth are shaped in a way that appear to wave back and forth when you spin the cassette around. If there isn't anything obvious blocking the cassette or lockring from seating straight you're probably fine.

As long as the lockring can engage enough threads in the freehub body, it shouldn't be a problem. But any spacers behind the cassette eat up clearance between the smallest cog and the dropout. I never use any spacers behind my cassettes.

A bit of runout in tha cassette (or feeewheel) is normal. Note the upper pulley on many derailleurs and see how much it will move side to side to compensate for the slight runout of some cassettes. That allows the derailleur to stay be in tune while the sprocket wobbles a bit.
