That's looks to be the countershaft. The bearing will come off with some whacks with a hammer, you just need to be careful when you do whack it, use a piece of wood to absorb the blows whilst loosely suspending the shaft in a vice so the shaft can move. The O ring is actually behind the bearing IIRC, it seals the bearing against the spacer which is what the outer seal uses. That will also come off if you want to clean it.
The problem is the bearing is almost unobtainable these days, very few left around. If it's not rumbling I'd leave it alone.

Agreed. I’m pretty sure the only way to get a bearing is to purchase the entire assembly. Like the man said, if it ain’t rumbling, leave well alone.

The red arrow is the BRAND SPANKING NEW ONE
Got it in the states whilst I was there! NOS
The blue arrow is the set ring for that shaft, it’s the smaller one I need mate.

Lucky man, not many about.
Getting it off is fairly easy, it's getting it on that can be a problem. Hitting the sprocket end of the shaft isn't that much of a problem, it's fairly solid steel BUT I'd still use something between the shaft and the hammer, thin piece of metal maybe. However when installing the bearing you need to hit the other end and that's a lot more fragile, I seem to recall some brass bushing inside the shaft, so protecting the end of the shaft is vital because if you deform it then the needle bearing won't go on or it will bind inside it.
The O ring should be easy to find I reckon, nothing special about it, just really thin.
Don't forget, DON'T reuse the circlips. Not worth the risk.
