Idling speed setting in no-load conditions (standard)
Afterllingwithoil,fuelandcoolant,starttheengineandwarm
upfor10minutes.
Adjust idling speed at 850÷950 rpm by turning screw 1 then
tightenlocknut.

Note: Speeddecreaseswhenlooseningscrew 1andincreases
whentighteningit.
Injection pump delivery limiting and torque adjusting
device
LimitingdeviceChasthefunctionoflimitingtheinjectionpump
maximumdelivery
Thesamedeviceacts as torqueadjusting devicesince springs
N act on lever L and thus oppose the resistance of spring M
containedinthebarrel.
Thetorque limitingdevice allows lever L to haveastroke Hof
1.0÷1.1 mm: this increases the injection pump delivery while
torquereachesitspeak.
Note: Inapplicationforgeneratingsetsandmotorweldingunits
thetorque adjustingdevice onlyactsas delivery limiting
devicewithoutspring MandstrokeH.
Standard injection pump delivery setting without torque
dynamometer
This adjustment must only be carried if necessary and if there
isnodynamometricbrake,sincethistypeofadjustmentisvery
approximate.
LoosendeliverylimitingdeviceCby5turns.
Bringenginetomax.rpminno-loadconditionsi.e.3200rpm.
Tightenlimitingdevice Cuntiltheenginerpmdecreases.
UnscrewlimitingdeviceCby1÷1/2turn.
Tightenlocknut.
Note: If the engine, at full load, generates too much smoke
tighten C; loosen C if no smoke is observed at the
exhaustandiftheenginecannotdeliveritsfullpower.
Full speed setting in no-load conditions (standard)
Before carrying out this operation, make sure that the engine
adjustment is standard; i.e. corresponding to one of the power
curvediagramsshownonpages20-21.
Exampleofadjustmentofanengineat3000rpm:
After setting idle speed turn screw 2 and set full speed in no-
loadconditionsat3200rpm;thentightenlocknut.
Whentheenginereachesthepre-setpower,fullspeedstabilizes
at3000rpm.
Nota: Speedincreaseswhenlooseningscrew2anddecreases
whentighteningit.
