4-cyl. injection engine (1.8 and 2.0 l engine, chain drive) - Edition 08.2018  
– Check dimension between drive plate and cylinder block at  
three points and calculate average.  
Note  
Measure through hole in drive plate to milled surface of cylinder  
block. If measuring on the intermediate plate, the plate thickness  
must be taken into account.  
Specification measured without intermediate plate: 19.5…  
21.1 mm  
Specification measured with intermediate plate: 18.8…  
20.4 mm  
If the specification is not reached, replace all securing bolts and  
tighten.  
If specification is not attained:  
– Remove drive plate again and fit shim -A-. Tighten bolts -3-  
again to 30 Nm.  
– Repeat measurement. If the specification is not reached, re‐  
place all securing bolts and tighten.

– Apply silicone sealant as shown to clean sealing surface of  
sealing flange.  
♦ Thickness of sealant bead: 2 to 3 mm.  
Note  
The sealing flange must be installed within 5 minutes after ap‐  
plying the silicone sealant.  
The bead of sealant must not be thicker than specified, other‐  
wise excess sealant can enter the sump and obstruct the  
strainer in the oil intake pipe.  
Check sealing flange; it must be free of kinks and damage.  
The sealing lip must face engine following installation. If the  
sealing lip »folds out« during installation, oil leaks may occur.  
– Check guide - T10122/6- -(B)-; it must be clean and free of  
sharp edges.  
– Attach assembly aid - T10122/1- -(A)- to guide - T10122/6-  
-(B)-.  
– Push sealing flange -C-, leading with the outer side, onto guide  
-B-.  
– Remove assembly aid -A-.
