XS rear wheel on 600 shadow

[shortpork]

I don’t like the giant hub and chodey street tires available for the stock 15in shadow rear wheel, so I picked up a 16in xs wheel online.

Well baked me thought the axle sizes were the same cause I only half assed looked into it that night.
It’s the look I want and I can get everything else to jive but the shadow has a 16mm axle and the xs has a 20mm.

Could I...
Put a sleeve over the shadow axle the width of the xs hub to snug everything up??

The sleeve and axle would turn independently, but the hub all turns independently as well. I Would weld them together but couldn’t remove the back tire then.

I don’t see a problem with it but I don’t have mechanically minded friends to ask. Just looking for others opinions. Thanks

Can you change the bearings to fit the axle?

[shortpork]

I was thinking that but I’m not totally sure how that works. Wouldn’t the axle only be riding on the bearings rather than the entire width of the hub? It’s hard tailed so that seems like a lot of stress on a small area. But idk

Yup, just swap bearings to fit hub and axle. The axle should be riding on just the bearings.

Just measure the size of the outside diameter of the xs bearings (same as hub size of xs) and the axle diameter of the shadow, then find bearings to fit.

Bearings may be a different size on each side of the hub; often larger on the chain/belt/shaft (drive) side.

I took a quick look here and saw the left side for XS 650 rear wheel listed as a #6203-2RS bearing (25mmx62mmx17mm) and left rear bearing for shadow 600 as #6303-2RS (17x47x17).
Look for more bearings from All Balls Racing,

Thank you Trinort! So looking through th axle hole of the xs the hub and bearing look to be the same diameter. You’re saying I’m good to put bearings with smaller ID so the axle only rides in the bearings correct?
Sorry, paranoid about some of this stuff...

Yep that's what he's saying. Your good to go just get a smaller bearing.

The axle runs on the bearings and nothing else.

Cool! Thank you both for the help. Really appreciate it!

You will also need the right diameter spacer, which fits between the bearings, inside the hub.
Take a look here:

Here is a link to a xs650 shop manual pdf from xs650 chopper.com which may be helpful while dealing with that wheel:

Sweet thank you for that. I did some looking and I should be able to find what I need. If the new bearings I get are the same width then the spacer that’s in there should work still yeah?

[shortpork]

So I took my wheel apart and found this diagram.

Piece #20 it a top hat that goes into the sprocket side bearing ( which is larger than the brake side bearing). For this to work I would need that Tophat piece with a ID of 17mm.

When I was reading how to remove these wheel bearings people were saying to slide the spacer to one side so you can get your punch on the other sides bearing. My spacer had no movement, but would without this top hat piece. If my replacement bearing had my ID of 17mm would I need this top hat piece? Is the wheel spacer slop okay? Sounds like other bikes have some...
Thanks

Since you will not be re-using the bearings, you can follow the procedure the one poster explains from the link the the thread above:
"On these rear wheels, you don't have to go through that whole routine of sliding the spacer to the side to get at the bearing. That only needs to be done for the fronts. On the sprocket side bearing, there's a top hat shaped spacer (#20 below) pressed into it from the rear. Find a socket that fits on that and simply drive it into the hub. It will push the center spacer and the other bearing out. Then it's a simple matter to remove the sprocket side one with a drift of some sort."

Normally you only want to press on the outer ring of the bearing, which is what you can do when you install new bearings in the bores in the hub.

The spacer has to be the right length between the inner rings of the bearings, when the bearings are fully installed to prevent side-loading of the bearings - you don't want that.
You may be able to modify the one from the Shadow back wheel.

One way to measure for the spacer length is install one of the bearings until it is fully seated in the hub, then use a measuring tool (vernier caliper works great for this) and measure from the inner edge of the bearing to the seat of the bearing bore on the other side of the hub...you want the bearing spacer to be the same length as the distance between the inner faces of the two fully installed bearings.

Ok great info. So from your earlier post you say the spacer has to be the same diameter as the axle? Ie fit snug around the axle. If so I’d be back to my initial solution of a sleeve would seem the easiest.

[TriNortchopz]

I was confused with your original explanation and didn't understand about welding them together and the axle turning...

The sleeve and axle would turn independently, but the hub all turns independently as well. I Would weld them together but couldn’t remove the back tire then.

Spacer does not need to be a snug fit on the axle, it just needs to be the right diameter to fit against the inner 'ring' of the bearings...

I would measure the bearings and get new ones from a local bearing supplier.

[shortpork]

Oh okay. That makes sense.

So I found that the xs wheel spacer fits perfectly on the shadow inside bearing ring and the new bearings will have the same ID. The xs wheel spacer will be short since the Tophat won’t be used anymore but... I’ve got tube the same diameter as the stock spacer and the ring slides off. Looks like I’ll just make my own to length so long as it all jives up as planned.
