I'm going to take a shot here on how to draw it down.
I'm probably wrong. But here goes.
Take a look at the exploded view of the Hornady manual, page 23 I think. Or pull out your own manual. This is the new manual.

I have an older press, with an older manual. The old manual shows a washer between the index wheel and the yoke. The new manual does not have this washer listed. I actually though I might have lost my washer when I had my press apart, so I had Hornady send me a new washer. But I since believe I did not loose the washer. So I have not put it on. I just think my press is a transition between the 2 manual's
I just thought all the washer would do is allow the spring washer that's on the drive shaft,, inside the ram,,, to become more compressed. I didn't think it would effect the height of the drive hub because the hub floats so to speek.
But you know what. I'm going to tear this thing apart,,,, AGAIN,,, just to see what adding that washer will do. Maybe it will get rid of my little wobble by drawing down the shell plate to the sub plate.
I doubt it though. I'll probably just be wasting my time. Oh well.
