Alignment hole for TDC position is at front on timing case cover.
Crank engine at central bolt and secure vibration damper with
special tool 11 9 190 in firing TDC position of 1st cylinder.
Important!
When the engine is shut down, the inlet and exhaust
adjustment unit is normally locked in its initial position.
The situation may arise in some individual cases where this
initial position is not reached and the camshaft can continue
to be rotated in the adjustment range of the adjustment unit.
In order to avoid incorrect timing adjustment, it is essential to
check the locking of the adjustment unit and if necessary
perform locking by rotating the camshafts.
Checking locking of inlet adjustment unit in initial position:
Engage hexagon head of inlet camshaft and attempt to rotate inlet
camshaft carefully against direction of rotation.
If there is no fixed connection between inlet camshaft and inlet
adjustment unit, rotate inlet camshaft against direction of rotation
as far as it will go.
The inlet adjustment unit is locked in the initial position when the
inlet camshaft is non-positively connected to the inlet adjustment
unit.
Checking locking of exhaust adjustment unit in initial position:
Engage hexagon head of exhaust camshaft and attempt to rotate
exhaust camshaft carefully in direction of rotation.
If there is no fixed connection between exhaust camshaft and
exhaust adjustment unit, rotate exhaust camshaft in direction of
rotation as far as it will go.
The exhaust adjustment unit is locked in the initial position when
the exhaust camshaft is non-positively connected to the exhaust
adjustment unit.
