I guess these code on the back of the cases are the case bore sizes and I need to find out the crank main bearing journal sizes so for main bearing one the case is size “A” and the journal size is the number

It’s early days but want to work out now / understand  what I need to get as want to replace all shell bearings

Also I presume as all the crank webs have A1 the big ends are red?

Your casing is marked AABBB and your crank looks like 11111 which should give you Yellow Yellow Green Green Green.

Not going to guess which rod is which from the pics but crank looks all As so A1 – Red, A2 – Yellow, A3 – Green.

Hopefully someone will confirm.

I’m confused

I understand the big ends are all looking to be A1 but where do you get the 11111 from for the crank mains please

Big thanks for appreciation to all for this help

Best wishes Al

I have e-mailed you a copy of the excel sheet I made to help me identify the right colour codes.
