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: 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.27).

Oil filter

Fit the mesh type oil filter cartridge into the crankcase (fig.87) and
check that the rubber seals and the O-ring on the cover are in good
condition.
On request or KD 425-2 engines can mount an external filter cartrid-
ge that can be screwed onto the crankcase (fig.88). Oil the seal befo-
re assembly.

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 (fig. 89) by:
4. With the fuel feed pump cam in the rest position mount the pump
and actuate it manually .

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 con-
nection lever moves freely along its entire stroke.
Make the electrical connections as shown in diagram 90.
