The side to side should be the play in the gears. The up and down should be the bearings. They allow a little bit of slack. Not much. If it's a drivers license thickness it should be fine. Mine had about an inch up and down before I got it fixed.
As far as the side to side play, not sure about yours but mine has an offset steel bushing about 1.5 inches thick and about 4 inches in diameter. It sits in in the framework by the ring gear and the smaller gear of the turn motor goes in it. It is thicker on one side than the other and has notches. You have to pull the turn motor out to get to it. By rotating it you move the smaller gear closer to or farther from the ring gear. Thus taking up the slack. I don't know the tolerances on that but if it gets too much slack it could strip the gears and or have a run a way and spin out of control.
