Crankshaft Overview

Crankshaft Overview

• Secure engine to assembly stand using engine and transmission holder (VAS 6095) when performing repair work. Refer to => [ Engine, Securing on Assembly Stand ] Engine, Securing to Assembly Stand.






1 Cylinder Block

2 Bearing Shell for Cylinder Block

• With lubricating groove

• Lubricate

• Do not interchange used bearing shells (mark)

• Crankshaft bearing shells identification (classification), refer to => [ Crankshaft Bearing Shell Allocation ] Crankshaft Bearing Shell Allocation

3 Crankshaft

• after removal, lay aside so that sensor wheel - item 8 - => [ (Item 8) Sensor Wheel ] is not rested on and becomes damaged

• If the crankshaft is being replaced, then the bearing shells must be allocated to the bearing cover. Refer to => [ Crankshaft Bearing Shell Allocation ] Crankshaft Bearing Shell Allocation

• Axial clearance, refer to => [ Crankshaft, Measuring Axial Clearance ] Crankshaft, Measuring Axial Clearance

• Radial clearance, refer to => [ Crankshaft, Measuring Radial Clearance ] Crankshaft, Measuring Radial Clearance

• Do not turn crankshaft when measuring radial play

• Crankshaft dimensions, refer to => [ Crankshaft Dimensions ] [1][2]Crankshaft, Engine

4 Bearing Shell for Bearing Cap

• Without lubricating groove

• Lubricate

• Do not interchange used bearing shells (mark)

• Crankshaft bearing shells identification (classification), refer to => [ Crankshaft Bearing Shell Allocation ] Crankshaft Bearing Shell Allocation

5 Bolt

• Replace

• Tightening sequence, refer to => [ Crankshaft, Tightening Sequence ]

6 Bearing Cap

• Bearing cap 1: Belt pulley side

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

7 Bolt

• 10 Nm + 90° turn

• Replace

• Replace sensor wheel every time bolts are loosened, refer to => [ Sensor Wheel ] Service and Repair

8 Sensor Wheel

• For Engine Speed (RPM) sensor (G28)

• Only possible to install in one position - Bores are offset

• Replace sensor wheel every time bolts are loosened

• Removing and installing, refer to => [ Sensor Wheel ] Service and Repair

9 Thrust Washers

• Lubricate

• For bearing 3

10 Bolt

• Replace

• Tightening sequence, refer to => [ Crankshaft, Tightening Sequence ]

Crankshaft, Tightening Sequence





- Tighten the crankshaft bolts in the sequence - 1 to 5 -.

- Tighten the bolts - 1 through 10 - and - arrows A - hand-tight.

- Tighten the bolts - 1 through 10 - to 65 Nm.

- Tighten the bolts - 1 through 10 - 90° further using a rigid wrench.

- Tighten the bolts - arrows A - to 20 Nm.

- Tighten the bolts - arrows A - 90° further using a rigid wrench.
