Main Bearing Shells Allocation

The bearing shells are allocated to the cylinder block with the correct thickness at the factory. Colored dots serve to identify the bearing shell thickness.

The code letters on the lower contact surface or on the top of the cylinder block identify which bearing shell and where it must be mounted on the cylinder block (upper bearing shell).

The code letters on the crankshaft identify which bearing shells and where they must be installed in the bearing cover (lower bearing shell).

The first letter is for bearing cover one, the second for bearing cover two, etc.
