Tools for rear hub

Hi all
So my free hub is jamming up for the cassette. The cassette will not spin freely. It is a no-name hub, but found some videos for what looks like the same. I will need a 12mm hex key a tool for a 2 slotted flange (30mm) but the youtuber did not ID the tool
It fits in the photo below. Does anyone know what this is called?

If the pawls are beyond repair, do they sell this part as a whole?
It is a fat bike, so a new hub will be difficult to find
I appreciate the assistance
Thanks

2 notch freehub (note: NOT freewheel) tool should do you. Those notches should be 4mm I think and the diameter 28.5.

Try giving the freehub a good flush and lube. Try this before completely disassembling or replacing the freehub.

One challenge with taking apart freehubs and freewheels is the (near always) lack of available parts. If worn out or damaged pawls, or their spring(s), are found good luck finding replacements. This is why so many people will simply flush and lube the freehub body (or freewheel core) as it does the job that can be done with no special tools and in less time.

But given the chain gauged condition of the spokes and the "no name" hub reference (that now has a problematic freehub) I will say this wheel now has at least two strikes against it. If the hub/axle bearings are worn or if the rim is damaged (flat spotted, dented, bent, poor spoke tensions) I would suggest the wheel gets replaced in its entirety. Andy

New rear hubs that include the free hub aren't very expensive. You might consider that. If a local shop has a wheel person, then ask what they'd recommend. Sometimes a entire new wheel is even a better option. But if you want to learn to do build your own wheels, this might be a good opportunity. Try replace the hub with something the same flange diameter. Otherwise all new spokes can add up quick.

I don't mess with wheels myself anymore. I take them to the wheel person and then I can spend my time riding instead of fiddling. But some get more out of the fiddly stuff.

Looks to me like the chain jumped the large cog more than once.
If you rebuild, plan on replacing those outer spokes.

Thanks for the replies. At this point, I think I'll just replace the free hub without taking it apart. They are not expensive, but of course there are so many versions, I'll need to verify.
Yes, senor fattie has been used and abused. I adore this bike and have put it through some of the worst conditions. I maintain it regularly, but the free hub was beyond my tool drawer

Look at the spokes in your picture. The ones that have been chewed up by the chain having gone between the cassette and spokes should also be replaced

One more vote to replace the wheel or at least the outside spokes. Those gouged spokes may not break on your next ride, or the one after that, but you're going to end up needing to replace all eight of those spokes if you keep the wheel that long.

I doubt I will replace the wheel. The bike is not economically worth it.
The 12mm hex came in, and even with the help of a 2 ' helper bar I could not get the free hub to come off, so I did the desperate mechanics next step; I dripped oil into the free hub until the pawls started moving smoothly. Not sure how long it will last, but I'm sure at least as long as the spokes
