Crankshaft: Service and Repair

Crankshaft Overview

• Before removing the crankshaft, prepare for appropriate storage, so that the sensor wheel - item 4 - does not make contact or become damaged.

• Secure the engine to the engine and transmission holder (VAS 6095) when working on it.






1 Bolt

• 65 Nm + an additional 90° (1/4) turn.

• Always replace.

• Fully threaded.

• Tighten to 65 Nm to measure the radial play in the crankshaft; do not tighten the additional torque.

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 Screw

• 10 Nm + an additional 90° (1/4) turn.

• Always replace.

4 Sensor Wheel

• For the engine speed sensor (G28).

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

5 Crankshaft

• Axial play:

New: 0.07 to 0.23 mm

Wear limit: 0.30 mm

• Measure the radial clearance using Plastigage(R):

New: 0.017 to 0.037 mm

Wear limit: 0.07 mm

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

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