Upper Crankshaft Bearing Shell Identification
From the factory, the upper bearing shells are allocated to the cylinder block with the correct thickness. Colored spots serve to identify the bearing thicknesses.
The letters marked on the lower sealing surface of the cylinder block identify which bearing thickness must be installed in which location.
