Using the specific tool to turn the engine flywheel 99360321,
turn the crankshaft in the opposite direction to that of
operation until the pointer of the dial gauge reaches the
minimum value beyond which it can no longer fall.
NOTE The measurement must be taken holding the
rocker roller in contact with the profile of the
exhaust cam of the camshaft.
reset the dial gauge.
NOTE The dial gauge is to be zeroed with the rocker arm
roller in contact with the base radius of the cam
profile .
This occurs when the flywheel is turned in the
opposite direction of the operating direction
approx. 1 and 1/4 rotations.

reset the dial gauge first in point A.
NOTE The dial gauge is to be zeroed with the rocker arm
roller in contact with the base radius of the cam
profile .
For this, turn the flywheel until it exceeds
protrusions (A-B) and (B-C) on the cam profile
connected to the engine brake operation.
This condition occurs when the flywheel is turned
in the opposite direction of the operating
direction by approx. 1 and 1/4 rotations.
