Crankshaft Bearing Shell, Allocating

The bearing shells are allocated to the cylinder block with the correct thickness by the factory. Colored dots identify the bearing thicknesses

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 installed 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 cap (lower bearing shell)

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

Cylinder Block





The cylinder block identification may be located either on the oil pan sealing surface or on the top (transmission side) of the cylinder block

The identification on the cylinder block is for the upper bearing shell





Note the letters and then match them to the color identification in the table

Crankshaft





The identification on the crankshaft is for the lower bearing shell

Note the letters and then match them to the color identification in the table
