– Tighten crankshaft bolts in the sequence -1 … 5- as follows:  
1 - Tighten bolts -1 to 10- and -arrows- by hand.  
2 - Pre-tighten bolts -1 to 10- to 65 Nm.  
3 - Turn bolts -1 to 10- 90° further using a rigid wrench.  
4 - Pre-tighten bolts -arrows- to 20 Nm.  
5 - Turn bolts -arrows- 90° further using a rigid wrench.

4-cyl. injection engine (1.8 and 2.0 l engine, chain drive) - Edition 08.2018  
– Remove camshaft timing chain and drive chain for balance  
shaft ⇒ page 114 .  
– Unscrew conrod bearing cap.  
– Remove crankshaft bearing cap.  
– Remove crankshaft and unscrew sender wheel.  
– Renew sender wheel -2- each time bolts -1- are loosened.  
Note  
The second time the bolts are tightened, the contact points in  
the sender wheel for the countersunk heads are deformed so  
far that the bolt heads seat on the crankshaft -3-, -arrows- and  
the sender wheel is »loose« under the bolts.  
Sender wheel can only be installed in one position. The holes  
are offset.

3.1.2  
Allocation of crankshaft bearing shells  
(classification)  
Bearing shells of the correct thickness are allocated to the cylin‐  
der block at the factory. Coloured dots are used to identify the  
thickness of the bearing shells.  
Which bearing shell is to be inserted at each place in the cylinder  
block (upper bearing shell) is marked by letters on the lower seal‐  
ing surface or on the front side of cylinder block.  
Which bearing shell is to be inserted at each place in bearing cap  
(lower bearing shell) is marked by letters on the crankshaft.  
The first letter is allocated to bearing cap 1, the second to bearing  
cap 2, etc.  
Cylinder block:  
The marking on the cylinder block can be found engraved either  
in the sump sealing surface or in the front end (gearbox side) of  
the cylinder block.
