Removal and Replacement



Crankshaft, assembly overview





1 - Bearing shells 1, 2, 4 and 5
^ For bearing cap without oil groove
^ For cylinder block with oil groove
^ Do not interchange used bearings (mark)

2 - 65 Nm plus an additional 1/4 turn (90°)
^ Replace
^ Tighten to 65 Nm to measure radial play, do not turn further

3 - Bearing cap
^ Bearing cap 1: Belt pulley side
^ Bearing cap 3 with notches for thrust washers
^ Retaining tabs of bearing shells and cylinder block/bearing caps must lie above one another

4 - Bearing shell 3
^ For bearing cap without oil groove

5 - Thrust washer
^ For bearing cap 3
^ Observe locating point

6 - Needle bearing

7 - Sensor wheel
^ Replace if damaged
^ For Engine speed (RPM) sensor -G28-
^ Replace sensor wheel every time bolts are loosened

8 - 10 Nm plus an additional 1/4 turn (90°)
^ Replace

9 - Fitting pin
^ Check projection from crankshaft

10 - Crankshaft
^ Axial play, New: 0.07 to 0.17 mm; Wear limit: 0.37 mm
^ Check radial clearance with Plastigage: 0.03 to 0.08 mm; Wear limit: 0.17 mm
^ Do not turn crankshaft when measuring radial play
^ On vehicles with manual transmission, drive in needle bearing if necessary

11 - Thrust washer
^ For cylinder block, bearing 3

12 - Bearing shell 3
^ For cylinder block with oil groove





Checking projection of fitting pin from crankshaft

Special tools, testers and auxiliary items required
^ Depth gauge

Work sequence
- Check projection - a - of fitting pin with sensor wheel - 1 - removed, using a depth gauge.
1 - Sensor wheel
2 - Bolt
3 - Fitting pin projection - 3 - from crankshaft a = 2.5 to 3.0 mm





Sensor wheel, removing and installing
- Replace sensor wheel - 2 - any time bolts are loosened - 1 -. Tightening torque: 10 Nm plus an additional 90° (1/4 turn)

Note: If a second tightening of the sensor wheel is performed, the fastening point of the countersunk screws in the sensor wheel is so far deformed that the screw heads line up - arrows - at the crankshaft - 3 - and the sensor wheel is loose under the screws.
