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.
4. With the fuel feed pump cam in the rest position mount the
pump and actuate it manually .
Feed pump
1. Insert the fuel feed pump tappet into its housing and make
sure that it moves freely.
2. Fit the 0.2 and 1mm adjustment gaskets.
3. With the fuel pump excenter in rest position the tappet
should protrude from the gasket surface (g. 89) by:

Oil lter
Fit the mesh type oil lter cartridge into the crankcase (g.87)
and check that the rubber seals and the O-ring on the cover are
in good condition.
On request, engines can mount an external lter cartridge that
can be screwed onto the crankcase (g.88). Oil the seal before
assembly.
