2Remove spark plugs To ensure that the  
engine can be easily  
cranked when drawing in  
the timing chain, and to  
avoid the timing chain 
jumping across.  
Remove only one spark  
plug at each cylinder.

6Position engine at a 40°  
crank angle before  
ignition TDC of cylinder  
1. Engine must not be  
cranked back.  
The notches of the  
camshafts must be  
pointing in the direction of  
the inner V.  
It must be possible to  
easily insert the two  
locking plates.  
If this is not possible: ? 
Set the basic position of 
camshafts.AR05.20-P-6020AU
 The copper tabs of the  
timing chain must be  
aligned with the markings  
on the camshaft sprockets. 
Because of the unevenly  
long travel of the timing  
chain it may be necessary  
to crank the engine as  
much as 14 times until the  
copper tabs are aligned  
with the markings on the
