Main Bearing Shells Allocation

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

The letters on the lower sealing surface or on the front side of the cylinder block indicate which bearing shell must be inserted at which position in the cylinder block (upper bearing shell).

The letters on the crankshaft indicate which bearing shell must be inserted at which position in the bearing cap (lower bearing shell).

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