Hello,

I am assembling the B18c bottom end and looking for the color of the main and rod bearing
This is my first time to check for the color code.
there are also "No.3" stamped on the connecting rods and 'C' on the crankshaft , that mean color code 3C = Brown , Do you guys try these are also in same thickness? That's make me confuse I am wrong to get the colour code.

and the main bearing code as below:
C4 =black
B3 =green
C3 = brown
C3=brown
B3=Green
