Why the Engine Serial Number Matters

Every MTU Series 4000 engine is built with specific production updates throughout its manufacturing life.

Before ordering spare parts, always have:

3. Arrangement Number
4. Emission Level

The engine identification plate is normally located on the starboard side of the engine block.
