How to fix displaced nuts/washers in hub axle?

Hello, everyone.

I've just replaced the freewheel on my bike for the first time, after lots of trial and error. But there's one problem I can't work out how to solve: I must've displaced the nuts and washers on the hub axle because one of the two nuts that fix the wheel to the frame isn't getting enough axle, while the other is getting too much, as shown in the pictures (note: the bike is upside down):




What I've unsuccessfully tried to do is remove the axle again, in order to move the nuts/washers on both sides in such a way that the hub is moved towards the left, giving more room to the washer on the right. The problem is that now the axle is not coming out after undoing the buts/washers on the left. In fact, not even the right-hand washers are moving.

It shouldn't be so hard, should it? It was so easy when I did it the first time: I undid the left-hand nuts and the whole axle came out.

Might I have broken anything? What do you suggest me to try?

Thanks in advance!

OK, bad news you'll have to take it apart a bit.

What happened is that while you had it apart, you either put the spacers on the wrong side, and/or walked the axle across while adjusting the cones and locknuts.

The right spacing is such that the axle locknut on the right is about 3/16" beyond the face of the freewheel, so when it's mounted there's room for the chain between the outer sprocket and the frame. The rest of the spacers go on the left, and the entire system is adjusted so the same amount of axle sticks out both ends.

Do you have enough room for the chain to go into the smallest gear without rubbing against the frame? If so, then you can keep the spacers as they currently are, and just basically have to thread the axle through the hub (loosening the cones on the non-drive side, and tightening the cones on the drive-side).
If you don't have room for the chain to go in the smallest gear without rubbing against the frame, you'll need to re-space things as well. I often measure combinations of spacers (between the cone and locknut), which could help you if you need to re-space.

You have to remove the freewheel. Then using the 15mm and 17mm hub cone spanner loosen the axle locknut on the left side. Move this a few threads out. Then loosen the right side axle locknut and move this a few threads in. Put the wheel on the bike to check if the axle is in the correct position. Once it is shifted correctly, tighten the axle locknut with the hub cone spanners. Make sure that the axle is not too tight that it grinds onto the bearing ie. the axle should spin smoothly without too much side play.

Thanks everybody for your help!

Right after I managed to re-space the nuts as per your advice, I noticed that I had fitted the axle opposite way, so I had to move the nuts back to their original positions.

All's well that ends well.
