6.9.2 Adjusting injection delivery (with
dyno break)
1 - Start the engine and bring it to the
operating temperature.
2 - Bring the engine to maximim rpm allowed.
3 - Loosen the locknut (A).
4 - Firmly tighten the screw (B) of the flow
limiter.
5 - Activate the dyno brake to bring the engine
to maximum power and speed.
6 - Make sure that fuel consumption
corresponds to the recommended values
(see “Table of specific fuel consumption”).
If fuel consumption does not correspond to the values
shown, reduce the load of the dyno brake.
7 - After a few minutes of running the engine and when it
has “stabilised”, slowly unscrew the limiter screw (B)
until the speed starts to decrease.
8 - Fasten the screw (B) with the locknut (A).
9 - Deactivate the dyno brake and take note of the
“stabilized” engine speed.
10 - Switch off the engine and leave to cool.
11 - Check the valve-rocker arm clearance (see “Adjusting
valve/rocker arm clearance”).
1 - Remove the preassure switch (A).
2 - Mount a union in the hole (B) and connect
to a 10-bar pressure gauge (C).
3 - Start the engine and bring it to the
operating temperature.
4 - Start the engine and bring it to a speed of
900 RPM, while at the same time making
sure that the pressure gauge shows a
pressure of 1 bar (oil temperature 80÷120
°C).
5 - Switch off the engine.
6 - Remove the pressure gauge (C) and the
union (B).
7 - Replace the pressure switch (A) and
tighten it to a torque of 25Nm.
Important
If the engine gives off too many fumes at maximum
load, loosen the flow limiter screw. If it gives off no
fumes or does not achieve maximum power, tighten
the flow limiter screw.
