Remove bearings from Mag Wheel?

[DieselTech]

It's basically a hollow tube that sets you bearing preload from being too tight, it rides over the axle shaft & between the bearings. Kinda like a spacer.

The crush sleeve is also that thicker part in the middle of the axle that keeps the bearings in place, correct? I think on his axle they might be integrated into it. Mine are as it they are machined or a super tight fit.

Yes some are set up with shoulders on the axle, to set preload on the bearings. Also could have a variant of both with shoulders & spacers.

This is the new axle kit they are sending to me.

Wow there is alot of ways to do this, it's really not that hard. I'm surprised the op's axle pulled through/out it shouldn't it should be stepped but looks like they went the cheap and easy way now! These are the axles they used to use no inner spacer needed the step sets the bearing inner race so as not to be misaligned with the outer, this also makes removing the bearings easy as you just put a nut on the axle end and and smack it with dead blow/hammer.

That is how my axles look.

Have you had a chance to get a old axle out yet? I'm just curious what your old 1 looks like?

The old axle for the bearings that are in place now was a straight shaft (of course threaded at each end). Same diameter the entire length. 9.83mm I believe is what I measured... from memory. The second axel set they sent me with bearings is shouldered about 1/4 inch in from the threads with that main body measuring 10.XXmm. The 1/4 inch shoulder is the 9.83mm diameter of the existing and the new bearings that came in this kit I got from them already. So when they sent me that axel to replace the slightly bent one for the rear, and the missing nuts and retainer washer for the front hub, it would not fit in the existing bearings because of the shoulder. First they told me to replace everything with the new bearings and new stepped axle, but then the next day they said don't use that axle and they wanted to send the kit I posted earlier but I said don't bother, I would use the existing slightly bent axle (the new one had a wobble in it too so I just decided it was as accurate as China can make them) and told them not to send this second new kit. Then after I ran the bike and took the front wheel off, i realized the bearings were seized and that they had just been spinning on the shaft for that 8 miles of riding last weekend. Glad I greased it before assembly, but sorry I did not realize the bearing was not turning..... That is how we got to where we are today but now I have to remove the bearings as they are defective.....sheesh... way too much going on here!!

Yeah I think when I get a set of mag wheels, I'm just going to replace bearings when i get the wheels, maybe the axle 2 depending on what shape there in. Seems like here lately all the mag wheels either have bent axles or bad bearings.

This is what the stepped/shouldered axle does when setup with good bearings and a balanced wheel, the wheel is just sitting on the axel's end with the nut on to give a little bigger footing.
The axle is not turning just the wheel and bearings with surprisingly little resistance.
