I can't find the answer. I seem to remember it is the same as stock Nachi 45BG07S5A1G-2DL

Externally it looks fine but it sounds like shaking a can of stones when running (has done since new but is 6 years old now).

Can anyone confirm? Thank you.

Did you ask Eurocharged?

No, I thought this would be well known and much quicker, I would guess all 83mm pulleys will be the same regardless of where they came from. I will email them if no one knows and post it.

Agreed, that is usually the case yes

Eurocharged (Jerry) replied very quickly and gave me the link above - 45BG07S5A1G-2DLCS which would be a stock sized bearing.

Thanks for putting the answer here!

No problem. Unfortunately for me on closer inspection, it looks like I need a whole new pulley. The pulley has been spinning around the bearing and there is some forward backward movement of the pulley on the bearing. I guess need to decide what to do, 83mm again, fixed pulley, back to stock, or smaller pulley. I would have tried 80mm but I don't think anyone is making them any longer.

Yes, I have been looking for an 80 also. Anyone konw why no one is making them?

It was brought out by VRP but is no longer on their website. Could email them. It looks like eurocharged have taken all of their non tune products away too. I am going to put my stock pulley back on and wait for a sale on fixed 83mm + tune.
