Allocation of main bearing shells |
Bearing shells of the correct thickness are allocated to the cylinder block at the factory. Coloured dots are used to identify the thickness of the bearing shells. |
Letter codes on lower sealing surface or end of cylinder block indicate which bearing shell is to be fitted in cylinder block (top bearing shell) at each location. |
Letter codes on crankshaft indicate which bearing shell is to be fitted in bearing cap (bottom bearing shell). |
The first letter stands for bearing cap 1, the second letter for bearing cap 2, etc. |
