^ Bearing 1 is located on the belt pulley side





Fig. 2 Removing crankshaft bearing cap

- Unscrew bolts or nuts for crankshaft bearing caps.
- Remove crankshaft bearing caps from cylinder block using T10055 extractor.





Fig. 3 Application of crankshaft bearing shells for cylinder block

Bearing shells with the correct thickness are allocated to the cylinder block in the factory. Colored dots on the bearing shells serve for identifying bearing shell thickness.

Note: The arrow points to the belt pulley side.

Application of bearing shells to cylinder block is marked by a letter beside the respective bearing.








Fig. 4 Application of crankshaft bearing shells for bearing caps

Bearing shells with the correct thickness are allocated to the bearing caps in the factory. Colored dots on the bearing shells serve for identifying bearing shell thickness.

Application of bearing shells to crankshaft is marked with a letter sequence at the crankshaft flank. The first digit, "1" (arrow) identifies the color coding for bearing 1.








Fig. 5 Installing crankshaft bearing cap

- Replace bolts -A- and nuts -1- to -8-.
- Inserting alignment bushings into cylinder block
- Tighten bearing cap nuts or bolts in following sequence:

1. - Screw in bolts -A- hand tight.
2. - Tighten nuts -1- to -8- to 35 Nm.
3. - Tighten nuts -1- to -8- 90 ° (1/4 turn) further using rigid wrench.
4. - tighten bolts -A- to 20 Nm.
5. - Tighten bolts -A- 90 ° (1/4 turn) further using rigid wrench.
