Hi,

My crankcase is marked BBBBA. I need both Mains and big end shells. The crank has been checked and has minimal wear. Mains are 31.978mm, Big Ends 31.983mm. Can anyone tell me which would be the correct shells to go for please?

Hi Brian,

Try this link, it may help you, I had the same issue:

There are also a few other links relating to bearing shells, use the 'Search' option on the specific forum, i.e CB350/400.

BrianC500:
Cheers Dave. I'l let you know how i get on

BrianC500:
I think I've worked this out correctly.....here goes

Mains measure 31.978mm, Big ends 31.983mm, Crankcase letters are BBBBA

Crankshaft is 1A 1A 1A 1A 1

Conrods are 2C 2C 2C 2C

I think I need Mains Green, Green, Green, Green, Yellow

Big ends Brown, Brown, Brown, Brown.

Could some very kind fellow forum member confirm that for me please?
