Allocation Of Main Bearing Shells From Production Date 09/24/2012

WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

It is absolutely necessary to observe the production date. The production date is located on the crankshaft counterweight. Determine the production date. Refer to MAIN BEARING SHELLS ALLOCATION .

The main bearing shells are allocated to the cylinder block and crankshaft with the correct thickness at the factory. Colored spots serve to identify the bearing thicknesses.

If the cylinder block or crankshaft are being replaced, then the bearing shells must be allocated.

The correct color code for the bearing shells needs to be determined by the letters on the cylinder block and the crankshaft.

The first letter is for crankshaft bearing 1, the second for crankshaft bearing 2, etc.
