PREPARING THE ENGINE FOR A LONG PERIOD
OF INACTIVITY
In the case of a planned period of inactivity that lasts longer
than two months, to prevent the interior parts of the
engine and some components of the injection system from
oxidizing, prepare the engine as follows:
1. Drain the lubricant oil from the sump after heating the
engine.
2. Pour 30/M protective oil into the engine up to the
“minimum” level indicated on the oil level dipstick. Start
the engine and run it for approx. 5 min.
3. Drain the fuel from the injection circuit, from the filter
and from the injection pump channels.
4. Connect the fuel circuit to a tank containing CFB
protective liquid (ISO 4113) and introduce the liquid by
pressurizing the circuit and driving the engine for
approx. 2 min. after excluding injection system
operation.
The operation required can be completed by directly
polarizing terminal 50 of the electric starter motor with
positive voltage equal to that of the nominal system voltage,
using the designated conductor.
5. Nebulize the 30/M protective oil in a quantity of
approx. 130 g (10 g per liter of displacement) in the
turbocharger intake inlet, during the engine turning
operation described in the previous paragraph.
6. Close all of the engine’s intake, discharge, ventilation
and bleeding holes with plugs or seal them with
adhesive
tape.
7. Drain the residual 30/M protective oil from the sump,
which can be used for an additional 2 preparations.
8. Place warning notices of ENGINE WITHOUT OIL on the
engine and dashboard.
Using Illustration 2:
1. Loosen the nut (2)
2. Disconnect the fittings (1)(4).
3. Remove the vapor recirculation pipe (3).
Using Illustration 3:
1. Unscrew the nuts (6) and remove the cover (5) of
the blow-by filter, together with the diaphragm valve
and breather pipe.
2. Release the safety circlip (4) and remove the blow-by
filter (1) from the threaded bushing (3) and spindle(2).
3. Replace and install the new blow-by filter on the
spindle (2) with the threaded bushing (3) and secure
with the circlip (4).
4. Fit the cover (5) with the diaphragm valve and
breather pipe. Tighten nuts (6).
5. Fit the oil vapor recirculation pipe, connect the relative
fittings and screw on the nut.
6. Correctly position the guards inserting the anti-
vibration
plugs.
7. Secure the other guards.
