Title: Honda CB 400 four bearing codes
Post by: eem46 on May 09, 2017, 11:12:33 AM

Dear All,

I know this subject passes a lot on the forum, but this is my first Honda CB 400 Four engine so I would like to double check the bearing info.

My crankcase stamps outside are BBBBB
My crank paint says: A1 A1 B1 B1 2
My conrods paint says: 1 2(bit blurry, see pic) 3 3

So my cranks bearing codes are: B1 B1 B1 B1 B2, so that is Green, Green, Green, Green and ? (Please advise color shell B2)

Conrods will be: A1 A2 B3 B3, so that is ? Yellow ? ? Please advise color shell A1 and B3

Thanks a lot.

Kind regards,

Emiel

Thank Oddjob.

So buy the stuff and plug and play.... so no double check with Plastigauge?

Kind regards,

Emiel

Thanks Oddjob!

Do you also agree that the number in the picture on the conrod is a 2?

Kind regards,

Emiel
