Live Centre looks to be dead

I have a ROTOR C2 Super live centre that isn't spinning freely. I took a look at some videos for disassembly for a live centre but I didn't see anything that looked similar. Since I do not have any experience with taking apart a live centre I would like a second opinion on this one. There is a split in the ring that secures the roller bearings. Safe to assume that is not by design. The ring around the roller bearings appears to be threaded but I am not certain. Anyone take a live centre like this apart before?

Thank-you

I had issues with my Rotor as well.

They had put one of the thrust bearing races backwards (as shown in the picture).

I honestly can't remember all the details of the disassembly. But I believe that split in the cage of the roller bearing is supposed to be there so that you can adjust the preload.

After viewing your images the only view I didn't see was one similar to the first image I posted. I assume yours looks the same from the front?
At this point do you think the internals should come out with some persuasion from the rear? Slide out past the threads?

I believe so, yes. Maybe squirt some penetrating oil everywhere and carefully tap it out.
 
“Rotor” is a pretty high class center (I have one in MT5, very nice). Yes, they come apart (mine needed cleaning and lubrication). I don’t recall the exact details, proceed like Stelster says - carefully. I know I ended up making a few simple tools. It is sort of like one of those wooden puzzles, you just have to figure it out. I’ve had a few rotating centers apart, every one was different - cool to see how different manufacturers do things.
 
I just happened to be trying to figure out how to get my Royal Versa-turn precision (half a tenth) live center apart when I saw this thread. Not sure it helps but here is a blowup I saw for mine.

I'm thinking I'll drill a hole through the shank so I have something to pull it apart with.
