What's wrong with your original bearing Nigel. Has the engine done high miles? Mine has done 22k and by the looks of the top end it's been looked after so kind  of hoping I won't need that bearing. Or are they prone to failure on the 500? What I did with my CB750K0 was to buy a really low mileage gearbox / primary sprocket assy. which cost me about 70 quid after customs, shipping etc (in fact I bought two so if anyone wants to buy one for what I paid).

Hi Ash, sorry for the delay in replying to your question, there's nothing wrong with my bearing, but I have the chance to get some made, by a bearing manufacturer, In small quantities. They want a bearing to measure before they quote, and I was a bit reluctant to send them my only bearing. I've sourced a scrap countershaft with the bearing on it, which they will have later this week, and I'm waiting to hear what they will cost. If they're reasonable I'll get some made.
Regards,
Nigel.

Picked up a  Genuine Honda   91001-283-000 today and he confirmed it is centre grooved. Guess I need to check with him it's 57 mm Dia before he ships it as a bit confused as it doesn't have the -003 suffix. given in the Cb500/4 manual and is listed for a CB450 up to CB500T. Are you out there Nigel and Oddjob (Ken).  May not even need one but with the rarity factor I thought I would take a punt as it was in the UK.

Ash; If it's at the right price I'd buy it straight away. I managed to find a new one too; but it came with a new countershaft. All the other bearings are available; it's just this one that seems elusive at the moment, so well  done for finding it. Have you also got the half locating ring for it?

Yes I bagged it as soon as I spotted it yesterday Nigel. He's not shipping yet as he's looking for a few CB250K bits for me too. Locating ring was present in the crankcases. Every Honda parts manual list that bearing as 5205 including the CB500T one, which , as you spotted, is incorrect.

Surprised nobody has bagged this (I got the other one he had)

Well done Ash! You got a billy bargain there! With regard to getting these bearings; I contacted Nachi; they declined to quote. So I don't think these will be available much longer! The good thing as you said was that they don't wear out very often!

Had an eye on it, but he wouldn't ship to the continent...
