Main Bearing Shell Allocation: Notes
WARNING: This page is about a different car, the 2013 Volkswagen Beetle and 2012 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.
The bearing shells are allocated to the cylinder block with the correct thickness by the factory. Colored dots serve to 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 in the cylinder block (upper bearing shell).
The code letters on the crankshaft identify which bearing shell 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.
