To avoid excessive compression of the spark arrester A (fig. 152),<br />
check projection B of the nozzle (fig. 150).<br />
B = 6.80÷7.05 mm.<br />
If this measure is larger put spacer 2 between ring nut 1 and copper<br />

0.25 mm thick spacers are available.<br />

Injector, spark arrester<br />
Every time you remove the pump/injector you must replace the<br />
spark arrester, the copper gasket, the oil O-ring, as well as the 2 fuel<br />
O-rings.<br />
Insert the spark arrester in the injector housing with surface A<br />
pointing upwards.<br />
Tighten simultaneously both nuts that fasten it to the head at 20<br />
Nm.<br />
For engines with the injectors fixed with self-locking nuts, tighten<br />
