I don't know what this would be a part of, the hub, the cassette, something else?
Trying to get this apart so I can more easily put in grease and bearings. As you can see, it's been hit a little too hard by something, probably PO using a chisel and hammer instead of the right tool. I have the correct tool to remove it, it just keeps slipping because one side is well rounded. Any other ways outside of welding a nut on to get it out? Any tricks? I can hit it with the impact gun but unsure if the Park tool would survive and if it would just round this off more. Luckily, my fingers are small enough that I can regrease the bearings without having to get this off, but would like to be able to take it apart one day.
Can't wait to find a new job so I can just get a new wheel set lol.
