Yeah not sure why, ive seen 2nd hand cases labelled 3BN 00, 01 and 02. Maybe its the place of manufacture, or just subtle changes in materials or something? Ive noticed the 00 case has a couple of shallower indents on the outside of the case, and a couple of radius corners are subtly different. Could be a different manufacturer

Thanks mate. You know the quantities? The link has the type but not how many of each. Is it 2 balancer shaft bearings and 1 of everything else? Cheers.

The current engine is dtr 1997. So the 00 model case should fit?

Thanks Callum really helpful

My exisiting (but damaged) engine case is labelled 3BN 02. I have a lovely pair of 2nd hand cases to swap them out with. However, the replacement case is 3BN 00. Is this a number that signifies a difference in the case design or simply to line up with manufacturing year etc?

Thanks
James

I'm rebuilding my engine and changing the existing engine cases because they have a crack in them which lets the oil out. Question - where do i find information on all the engine bearings in the engine? Haynes manual? They are knackered but havent taken them out yet. Thanks.
