I noticed today that there's about 3mm of horizontal free movement between my cranks and BB (hollowtech midleburns onto shimano BB).
I assumed it was the adjuster ring that had come loose and needed tightening back up to the BB, but there are no threads on the axle section that becomes visible...
Does it need more spacers or have I messed up somewhere?

There should be threads on that axle, which the adjusting ring spins on. There are only about 4-5 though.

The BB cups might need spacing out more. I had to space out my 68mm shell with 3 spacers, which takes it up to about 75mm.

Hope that helps!

73 mm is the ISO oversize, 68, normal, so it'll be the difference.
