Part identification

[Boost]

Hey gokarters, I recently got a gokart from my friend, but of course since it was free it was not running. I got it running and all but there was another issue. A part that bolts onto the gear that goes to the tires rusted and cracked then fell off. I was wondering if anybody could help me find one online before I think about getting one machined. Here's some pics of it.

Here is where you can see its cracked:

It bolts to the gear that spins the tire as you can see here:

And here is the back and as you can see there's a bearing build into it:

To explain it a little more the part that cracked goes into the rim and bolts to it. The other side bolts to the gear. It basically connects the gear to the tire but on the other side it has the brake.
Thanks a lot I appreciate any feedback you guys can give.

Sorry about that I'm on mobile because my internet is down.
I don't have the option on mobile to downsize the images.
Edit: It is back up now and the images are resized.

Sorry best I have at the moment the rest are on my computer which doesn't have internet because its down for some reason today.
Yeah it might be homemade it has a few sketchy things on it. If I can't get this part reproduced what other options do I have?
Thanks for the help by the way I'm new to the whole gokart thing.
I really want to get the remade by my friend who is a machinist but it looks like the bearing is almost built into it. Not sure how I would go about doing that.

Post a pic of all the wheel components of the afflicted wheel...
That homemade piece is someone's way of working harder, not smarter....

I welded the part that cracked back together.
I will post updates tomorrow because I didn't get a chance to put it together yet. Tomorrow morning I will get a pic of how it works.
