GENERAL DATA
Scheme 149
The engine serial number and type are stamped on the left side of the cylinder block at the top of the mounting for the water pump.
There is also a decal on the timing casing with the engine type, manufacturing number, and serial number.
Scheme 150
The marking is stamped into the engine block and crankshaft. The classification marking is in the engine block above the oil cooler and crankshaft. The classification shall be read from the digit 1 to 6. The first letter after the digit 1 corresponds to the classification of main bearing 1. The bearing positions are numbered starting at the engine's leading edge.
- Classification cylinder block
- Classification crankshaft
