M156 Main Bearing Code Identification Guide


The M156 Engine has 5 main bearings. When ordering a Main Bearing Assembly, it is necessary to provide Weistec Engineering with the bearing code for your specific engine. It is vital that the code is provided to ensure that the proper bearings are supplied for your specific engine. The identification process is very simple. Actual assembly of an M156 engine must be performed by an experienced engine builder following Mercedes OEM specifications for torqueing procedures.


Location 1 is on the snout of the crankshaft. It is a 5 character code consisting of any combination of the following letters: R, Y, G, B. In the picture the code is circled in red.


Location 2 is on Bank1 side of the engine just behind where the engine mount bracket bolts on to the engine block. It is a 5 digit code consisting of any combination of the following numbers: 1, 2, 3, 4. In the picture below the code is circled in red. Note: Very early M156 engines may not have this code. If your engine is an early M156 engine and does not have the code in location 2, the code from location one is all that is necessary
