Front wheel slides back and forth on axle

I was recently given a GY6 49cc scooter. The only thing wrong with it is the speedometer doesn't work.

So after some tinkering, I discovered the speedometer cable wasn't spinning. I removed the front wheel and pulled the speedometer off. It looks like someone put it on wrong, tightened it down and bent the 2 tabs inside.

I disassembled the speedometer and straightened the tabs.

I reinstalled the front wheel and tightened the axle, everything appeared to be fine... except the wheel slides back and forth on the axle between 1/4" and 1/2". The bearings on both sides of the wheel are able to slide in and out the same distance as well, shouldn't they be pretty well fixed in place?

I'm wondering if this wasn't the issue with the speedometer to begin with? When the wheel is pushed towards the speedometer, the speedometer works, but when i'ts pulled to the other side, the hub is far enough away from the speedometer gear where it doesn't spin the speedometer.

Any help would be great, thanks!

Sounds like you're missing one or more axle spacers.

Here is a video of it, I think you might be right on the spacer issue.

Missing spacer? or maybe existing spacer/s put in backwards or on wrong side of wheel hub maybe?

After some measurements, the spacers are the correct length and all required parts are there.

When the axle is tightened down, the forks, axle, bearings, and spacers become a solid "assembly" if you will, and the wheel hub is able to move side to side over this assembly... which indicates to me that the bearings are not seated properly in the hub or the part of the hub that holds the bearing is worn.

I've ordered new bearings and Loctite 640 High Strength Sleeve Retainer to help hold the bearings in their correct position.

Hopefully this solves the problem, I will update this post after the weekend.

New bearings with loctite did the trick, everything works as it should now.

Thanx for the follow up. That includes the speedometer working as it should too?
