A Hole on flywheel with reference mark, corresponding to
the TDC of pistons 1-6
B Hole on flywheel with reference mark, corresponding to
the TDC of pistons 2-5
C Hole on flywheel with reference mark, corresponding to
the TDC of pistons 3-4
D Flywheel hole with two notches corresponding to posi-
tion 54˚ before TDC of pistons 1-6 (camshaft timing refe-
rence );
E Flywheel hole with three notches corresponding to posi-
tion 30˚ before TDC of pistons 1-6 (reference to high
pressure fuel pump timing system and phonic wheel
timing).
In order to perform adjustments correctly, during each rota-
tion phase, check the positioning accuracy using the tool for
TDC Engine 99360612, inserting it into the hole marked with
a notch on the flywheel corresponding to the position of the
