9 SETTINGS SPEED SETTINGS Setting the idle minimum (standard) After filling the engine with oil, fuel and coolant, start it and let it warm up for 10 minutes. Turn the screw 1 to adjust the idle speed at 850 to 900 rpm. Tighten then the locknut. Note: If you loosen screw 1 speed decreases. To the opposite direction speed increases. 176 Setting the idle maximum (standard) After setting the idle speed turn screw 2 and regulate the idle maximum at 3800 rpm. Block then the locknut. When the engine reaches its setting power, the maximum rpm will stabilise at 3600 rpm. Note: If you loosen screw 2 speed increases. To the opposite direction speed decreases. 177 Setting the stop Remove the rocker arms cover and completely unloosen screw B. Push rod A to the right and keep it in this position; see figure. Tighten screw B until it touches rod A. Release rod A and tighten again screw B by a 0.5÷1.0 turn. Tighten the lock nut. 178 Pump/injector unit timing with speed governor - Loosen the screws C of each pump/injector unit. - If it is not connected, connect spring D to rod A (with this operation the speed governor blocks are closed). - Move plates B of each pump/injector unit rightwards; see figure (with this operation the pumps/injector unit are at their maximum delivery). - Tighten screws C at 1.1 Nm. Re-balance the deliveries. Note: Spring D is the start-up fuel supplement spring: with the engine stopped pull rod A to the right by bringing the pump/ injector unit delivery to the maximum value, until the speed governor comes into operation with the engine running 179 - 74 - FOCS Workshop Manual_cod. 1.5302.858_1° ed_ rev. 00
Settings 9 Injection pump flow limiter and engine torque gearing device Flow limiter C has the function of limiting the injection pump’s maximum delivery. The same mechanism acts also as a torque gearing device. Indeed, under torque, spring N operating lever L overcomes the resistance of spring M located in the plunger barrel. The stroke H that the torque gearing device allows to be carried out by lever L, will increase the injection pump delivery and the torque will hit its maximum value. 180 181 PUMP INJECTION DELIVERY SETTING Pump injection delivery standard setting without dynamometric brake This adjustment must be performed with the dynamometric braked engine. Without this the regulation is approximate. In this case proceed as follows: 182 - Unlock the maximum flow limiter lock nut. - Fully screw in flow limiter C. - Run the engine to the maximum speed, that is 3800 rpm. - Loosen flow limiter C until the engine revs start to decrease. - Screw flow limiter C by 2.5 turns. - Tighten the lock nut. Note: If the engine under maximum load emits too much smoke unscrew C. Tighten C if at this load there is no smoke and if the engine does not reach its maximum power.

Injection pump flow limiter and engine torque gearing device<br />
Flow limiter C has the function of limiting the injection pump’s<br />
maximum delivery.<br />
The same mechanism acts also as a torque gearing device.<br />
Indeed, under torque, spring N operating lever L overcomes the<br />
resistance of spring M located in the plunger barrel.<br />
The stroke H that the torque gearing device allows to be carried out<br />
by lever L, will increase the injection pump delivery and the torque<br />
will hit its maximum value.<br />

PUMP INJECTION DELIVERY SETTING<br />
Pump injection delivery standard setting without<br />
dynamometric brake<br />
This adjustment must be performed with the dynamometric braked<br />
engine.<br />
Without this the regulation is approximate.<br />
In this case proceed as follows:<br />
182<br />
- Unlock the maximum flow limiter lock nut.<br />
- Fully screw in flow limiter C.<br />
- Run the engine to the maximum speed, that is 3800 rpm.<br />
- Loosen flow limiter C until the engine revs start to decrease.<br />
- Screw flow limiter C by 2.5 turns.<br />
- Tighten the lock nut.<br />
Note: If the engine under maximum load emits too much smoke<br />
unscrew C. Tighten C if at this load there is no smoke and if<br />
the engine does not reach its maximum power.<br />
