Injection pump delivery setting with dynamometric brake

1) Run the engine and bring it to the operating temperature.
2) Release the flow limiter screw C completely (see page 175).
3) Bring the engine to maximum rotation speed.
4) Activate the dynamometric brake to bring the engine to the maxi-
mum speed.
5) Check that fuel consumption is in line with the values given in the
table "Specific fuel consumption".
If it is not in line with the indicated values, reduce the dynamome-
tric brake load.
6) After a few operation minutes and when the engine has stabili-
zed, slowly fasten screw C until the rotation speed starts decrea-
sing.
7) Lock screw C using a lock nut.
8) Carry out the fuel consumption check again.
9) Release the dynamometric brake and detect the rotation speed of
the "stabilized" engine (maximum idle speed).
10) Bring the engine to minimum idle speed. Carry out engine setting
when the engine is "stabilized".
11) Switch off the engine and let it cool down.
12) Check the valve/rocker arm clearance (see "Setting valve/rocker
arm clearance").

lnjection pump delivery setting without dynamometric brake

Loosen delivery limiting device C by 5 turns.
Bring engine to full speed in no-load conditions i.e. 3200 r.p.m.. Tighten
limiting device until the engine shows a drop in r.p.m..
Unscrew limiting device C by 1 and ½ turns.
Tighten lock nut.
Note: lf the engine, under full load, generates too much smoke tighten
C; if no smoke is observed at the exhaust and the engine cannot
reach its full power unscrew C.
