Removal and Replacement

Crankshaft Overview

• The engine is to be secured to the engine lateral bracket (T03001) when performing assembly work.






1 Bolt

• 40 Nm + 90° (1/4) additional turn.

• Always replace.

• Fully threaded.

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

2 Bearing Cap

• Bearing cap 1: Belt pulley side.

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

3 Bearing Shell, for the Bearing Cap

• Without a lubricating groove.

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

4 Crankshaft

• Axial play new: 0.07 - 0.21 mm.

Wear limit: 0.30 mm

• Measure radial clearance using Plastigage.

New: 0.023 - 0.043 mm wear limit: 0.07 mm

• Do not rotate the crankshaft when measuring the radial play.

• Crankshaft dimensions, refer to => [ Crankshaft Dimensions ] Specifications.

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

5 Thrust Washers

• For bearing 3.

• The side lubricating grooves face outward.

6 Bearing Shell, for the Cylinder Block

• With a lubricating groove.

• Identification for replacement part ordering, refer to => [ Identification of the Upper Crankshaft Bearing Shells ].

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

7 Cylinder Block

Identification of the Upper Crankshaft Bearing Shells





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.

G Yellow
B Blue
W White

• The - arrow - points in the direction of travel.

• If the colored dots can no longer be read, use the blue bearing shell.

• The lower crankshaft bearing shells are always shipped as a replacement part with the "yellow" colored dot.
