Crankshaft Assembly Overview

Crankshaft Assembly Overview





1 Bolt

• Replace

• 40 Nm + 90° (1/4) additional turn.

• Fully threaded

• Tighten to 40 Nm (but not any further) to measure radial play in the crankshaft.

2 Crankshaft Bearing Cap

• Bearing cap 1: belt pulley side.

• Retaining tabs on bearing shells and cylinder block/bearing caps must lie above one another.

3 Bearing Shell (for Bearing Cap)

• Crankshaft bearing shell, allocating.

• Without a lubricating groove.

• Do not interchange used bearing shells (mark them).

4 Crankshaft

• Measuring axial play. Refer to => [ Crankshaft, Axial Play Measuring ] Crankshaft, Axial Play Measuring.

• Measuring radial clearance. Refer to => [ Crankshaft, Radial Play Measuring ] Crankshaft, Radial Play Measuring.

• Crankshaft dimensions. Refer to => [ Crankshaft Dimensions ] Specifications.

• Locking the crankshaft. Refer to => [ Crankshaft, Locking ] Procedures.

5 Thrust Washers

• For bearing 3.

• Side lubricating grooves face outward.

6 Bearing Shell (for Cylinder Block)

• With a lubricating groove/

• Crankshaft bearing shell, allocating.

• Do not interchange used bearing shells (mark them).

7 Cylinder Block

Crankshaft Upper Bearing Shell (for Cylinder Block) Allocation





From the factory, the upper bearing shells are allocated to the cylinder block with the correct thickness. Colored dots serve to identify the bearing thicknesses.

The letters marked on the lower sealing surface of the cylinder block identify which bearing thickness must be installed in which location.





• - Arrow - points in direction of travel.

• If the colored dot is not visible, use the blue bearing shell.

Crankshaft Lower Bearing Shell (for Bearing Cap) Allocation





• Bearing shells with the correct thickness are allocated to the bearing cap at the factory. Colored dots on the sides of the bearing shells serve for identifying bearing shell thickness.

• The allocation of the bearing shell for the bearing cap is identified by a series of letters on the crankshaft/vibration damper pulley flange. The first letter of the row of letters represents bearing " 1", the second letter is for bearing "2", etc.





• - Arrow - points in direction of travel.
