Injectors and injector pipes
Mount injectors to heads placing copper gaskets in between
(see pag. 36).
Connect the injectors to the pumps by way of the injection lines.
Important
• Important: always use two wrenches to loosen or tighten the
unions on the injector pipes (fig.86) thereby ensuring that the
position of the delivery valve holder on the pumps is not changed
(see pag.33).
Electric shut off
If the engine is equipped with an electric shut off, insert the
electro-magnet into the crankcase taking care to position the
engine shut-off lever in the STOP position; make sure that the
injection pump connection lever moves freely along its entire
stroke.
Make the electrical connections as shown in diagram 90.

On request, engines can mount an external filter cartridge that
can be screwed onto the crankcase (fig.88). Oil the seal before
