Iveco Daily. Manual - part 8
- no coolant leaks from coolant hose and cab interior
heating hose connection sleeves. Tighten hose clips, if
necessary;
- no oil leaks from between cover and cylinder head, oil
sump and crankcase, oil filter and housing, heat
exchanger and crankcase or from lubrication circuit lines;
- no fuel leaks from injection pump and injector lines.
Tighten fittings if necessary;
- check that the indicator lights on the instrument panel
and relating to the devices disconnected when the
engine was removed are working properly.
Refitting
To refit the power unit, reverse removal operations and
observe the following indications:
- before refitting gearbox to engine, remove thrust bearin
from diaphragm spring by opening circlip.
Fit thrust bearing on input shaft cover sleeve and
connect it to clutch disengagement lever. Smear input
shaft with Molikote molybdenum disulphate grease.
Engage a speed to rotate main shaft by rotating propeller
shaft flange. Push down the gearbox to properly engage
thrust bearing into diaphragm spring;
- take the utmost care when refitting the power unit into
engine compartment;
- check the conditions of the coolant pipes or sleeves and
of the air conveyors. Replace them if they show any sign
of deterioration;
- check the flexible mountings of the assemblies: engine
and gearbox. Replace them if they show any sign of
deterioration;
- check that the exhaust pipe members have not
deteriorated and are not about to deteriorate. If this is
so, replace them along with the flexible parts for securing
them;
- tighten the screws or nuts to the required torque;
- meticulously check the state of the vacuum pipe. It must
show no sign of cracking, cutting, scoring or of being
crushed. Replace it if there is any doubt at all about its
soundness. When mounting it, make sure the pipe does
not come into contact with sharp metal parts or corners
or with any particularly hot parts. In addition, after
assembly, the pipe must have no bends or constrictions,
its radius of curvature should be broad and it must be
secured to the vacuum pump fitting with a suitable
clamp;
- make sure that the quick-coupling fittings of the fuel
pipes are carefully cleaned and that, after their
connection to the relevant unions of the high-pressure
pump or of the fuel filter mounting, they are fully inserted
and do not get disconnected.
- fill the cooling system with coolant.
- bleed the fuel supply system as described in the relative
paragraph (only for engines 8140.63.4... - 8140.43C.4...);
- fill the power steering circuit and bleed the air as
described in the relevant paragraph;
- check the level of oil in the engine and gearbox;
- adjust the tension of the drive belt of the compressor for
the air-conditioner as described in ”Replacing Belts” (if
present).
Checks and tests
Start up engine, leave running at a speed slightly in
excess of idle speed and wait for coolant to heat
sufficiently to open thermostat. Then check the fol-
lowing:
!
When positioning the engine in the engine bay, take
special care not to damage the top pipe of the power
steering and the soundproof-heatproof cladding of
the engine bay.
Once positioned, meticulously check that the top
pipe of the power steering is sound.
Before using it again, check that the power steering
oil and coolant contain no impurities. If they do, filter
with suitable mesh filters. For any topping up, refer
to the REPLENISHING FLUIDS table in the
”GENERAL” section.

FUEL PIPES
1. High-pressure pump fuel pipe fast coupling - 2. Fuel
supply pipe fast coupling 3. Fuel return pipe fast coupling -
4. Fuel filter mount.
If the fuel pipes (1-2-3) get disconnected from the mount (4),
it is necessary, when refitting, to make sure their couplings are
thoroughly clean. This is to prevent getting a bad seal and fuel
leaking out as a result.
