The bottom halves of the bearing shells are assigned to the specific journal of the crankshaft by means of a letter engraved on the journal of the crankshaft. Each letter represents a color of the necessary bearing shell. EXAMPLE: If the first letter engraved on the crankshaft is a "r", than the first lower main bearing shell half is the Red main bearing shell half.
