Injection timing check
Top up the tank checking that fuel level is at least 10 cm above
checking device.
Adjust injection pump rack rod at half-stroke.
Turn the flywheel according to the engine direction of rotation and
check that fuel reaches the checking device.
Repeat this last operation; during compression proceed slowly and
stop immediately when the fuel is seen to pass through the
checking device hole; bring flywheel back by 5 mm: This is the so-
called static injection timing.
Follow the same procedure for the other two pumps considering
that the flywheel has top dead center reference marks for each
cylinder marked with 1, 3 and 2 and staggered by 120°.
