Bearing adjustment, Shimano rear wheel ***SORTED***

Noticed this morning on pre-ride check that the rear wheel had noticeable side-to-side play. Now, I understand how cups and cones work, but how in the name of (insert preferred sky-fairy name here) do you lock the drive side cone against anything? There's no way to hold it. I've looked at many youtube videos, but they all seem to merely explain how the basics work, which I understand.
The only way I can see to do this is to remove the axle completely, tighten the drive-side cone against its various outer bits, then rebuild and do the actual bearing adjustment from the non-drive side.
It's a standard Shimano hub on an R500 wheel, nothing remotely weird.
Your (fairly urgent) help appreciated!

Quick call to LBS seems to confirm that I need to completely remove the axle, lock it up, then reassemble.
That's my afternoon sorted, then...
:sad:

I don't mess around with the cone and nuts etc on the cassette side. I undo them on the non drive side, remove the axle from the drive side. Just clean it all as a unit and put it back in without unlocking the cone on the drive side.

That's what I do. So therefore it's probably wrong.

As @Dogtrousers says you don't need to touch the drive side at all. In many respects a hub bearing arrangement in shimano hubs is similar to an old loose cup and cone bottom bracket arrangement with a fixed side and an adjustable side - the drive side on the hub being the fixed.

Drop the wheel out and loosen the left side lock nut, tighten the cone up ever so slightly to eliminate any play and then using your cone spanner hold it in place and then re-tighten the locknut. This should take about 5 minutes or so.

Don't forget to check the wheel in the dropouts as tightening the QR applies load to the bearings.

What I'm saying is I found the drive side loose, I haven't done anything to it, except try to figure out how to lock it back up. So, steep learning curve it is, then!
:biggrin:

Ah I see. So the cone on the drive side (9) isn't locked anymore. It's free to spin around on the axle? I'd lock it up against (3) so that side is all solid and then carry on as before. (Which is what I think you said in your OP, so I'm not really helping)

That's fine, when you tighten up on the non-drive side it'll pull the axle over and lock it in place, then you're good to go. :okay:
That's the point, there's no way to lock them together except strip-down
They are certainly locked together now, and the hub is re-greased, re-assembled, and running smooooothly.
