Note! The illustrations in this service information are used for different model years and/or models. Some variation may occur. However, the essential information in the illustrations is always correct.

Engine manufacture number, engine serial number and type





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.

Classification of main bearings





The marking is stamped on the cylinder block and crankshaft.




1. Classification cylinder block
2. Classification crankshaft
3. Cylinder block
4. Intermediate section

General data (engine capacities)





Cylinder block








(1)The bore classification is stamped on top of the engine block. For example: 1CCDDE is read as cyl 1 = C, cyl 2 = C, cyl 3 = D, cyl 4 = D, cyl 5 = E.
