Cylinder Block Assembly: Locations

Crankshaft, removing and installing





1- Bearing shells 1, 2, 4 and 5
^ For bearing cap without oil groove
^ For cylinder block with oil groove
^ Do not interchange used bearing shells (mark)
2- 65 Nm plus an additional 1/4 turn (90°)
^ Replace
^ To measure radial clearance, tighten to 65 Nm but not further
3- Bearing cap
^ Bearing cap 1: Belt pulley end
^ Bearing cap 3 with recesses for thrust washers
^ Bearing shell retaining lugs in cylinder block and bearing caps must align
4- Bearing shell 3
^ For bearing cap without oil groove.
^ For cylinder block with oil groove.
5- Thrust washer
^ For bearing cap 3
^ Note securing arrangement
6- Sender wheel
^ For Engine speed (RPM) sensor -G28-.
^ Replace if damaged
^ Always replace sender wheel if securing bolts have been loosened
7- 10 Nm plus an additional 1/4 turn (90°)
^ Replace
8- Dowel pin
^ Checking projection from crankshaft
9- Crankshaft
^ Axial clearance, new: 0.07 to 0.17 mm; wear limit: 0.37 mm
^ Check radial clearance with Plastigage(R), new: 0.03 to 0.08 mm; wear limit: 0.17 mm
^ Do not rotate crankshaft when checking radial clearance
10- Thrust washer
^ For cylinder block, bearing 3





Checking dowel pin projection out of crankshaft

Special tools, testers and auxiliary items required
^ Depth gauge

Work sequence
- Use depth gauge to check projection - a - of dowel pin with sender wheel - 1 - removed.
1. Sender wheel
2. Securing bolt
3. Projection of dowel pin 3 out of crankshaft a = 2.5 to 3.0 mm





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

Note: The second time the bolts are tightened, the contact point of the countersunk head, in the sender wheel, is deformed sufficiently to allow the bolt head to seat - arrows - on the crankshaft - 3 -, thus allowing the sender wheel to remain loose under the bolts.
