In for a penny, in for a pound. That's the way it always starts, right?

I'm changing brakes pads on my TAG axle. I have one side done, and I'm working on the other... but this rotor has to be changed. I've never changed one on something this heavy, and closest job I've ever done is probably changing bearings on a boat trailer.  However, I'm not deterred, even if I should be.

I do have a tractor I can put a fork on and hold/lift the rotor, so this isn't a problem.  Here are my questions:

1. It appears I need two 8-sided sockets to remove this. My micrometer tells me they are 3 1/4" and 3 7/8". Does this sound about right? I can't find a parts explosion for this anywhere that shows me these nut sizes.  (I searched for Meritor 1560)
2. It also appears there is some kind of locking ring between the two afore mentioned nuts. And this locking ring requires its' own socket like thing, but I have no idea what specs are on this. Any idea exactly what tool this would be? (I have seen these sockets with teeth, in different sizes, so I know about what it looks like.)
3. I don't suppose there are places that rent heavy duty tools like this? This is probably a one-time deal for me, so I don't like buying one and done tools unless I have to. (But I'm thinking this isn't an Auto-zone tool loaner type of situation).
4. This final question maybe should have been my first question.  I have not been able to find anything that actually tells me specifically how to remove and reinstall the rotor. The Meritor manual just says to "remove the rotor from the spindle."  So now I'm guessing this must be documented in some other manual (maybe an axle manual), but I don't know where.  Hopefully this would tell give me the steps, tools needed, and torquing specs.

Thank you!
