Think it's pressed on like the CB250/350K. On that bike initially, the bearing and shaft were available separately but laterally only as a complete assembly due to difficulty in replacing the bearing. So, I think it can be done but you would need the right kit to do it. my problem on one of my CB250K engines was not the bearing it was the collar that the oilseal fits onto. Due to a period of not being used, the surface was corroded & pitted. I had the hardness of the collar checked and it had not been surface hardened so I did consider getting it machined down to suit the the next O ring ID size, however, I got a full gearbox off eBay in superb nick for £20 so I never bothered.
I have noticed how diligent he is when he posts, I'm also following him over on HondaTwins, and always look at both sites to see how he approaches solutions. Without people like him taking time out of their lives to help others the motorcycling world would be a lesser place. I'm pleased to know him, and the other regular contributors to these forums, without them I'd be stuck. Probably on the hard shoulder of a motorway.Regards,Nigel.
