The workshop manuals for mechanical parts have been divided into Sections, each of which has a number and its relevant contents
are indicated in the General Specifications. Each section features a main Unit (e.g. engine, gears etc.).
The subjects usually dealt with in each section are:
Technical data table, Driving torques, Equipment, Diagnostic, Removal and Fitting in place, Repair operations.
Where possible, the same sequence of procedures has been followed for easy reference.
Diagrams and symbols have been widely used to give a clearer and more immediate illustration of the subject being dealt with, (see
next page) instead of giving descriptions of some operations or procedures.
Example
Ø 1 = housing for connecting rod small end bush
Ø 2 = housing for connecting rod bearings
Furthermore, within each section, every heading or sub-heading concerning the operations to be carried out is preceded by a six
digit number. This number is the Product Code that is to be found in the repair operation described in the REPAIR TIMES CHARTS
and in the FAULT CODES.
For quick reference the indication of how to read this code is described below (see the Repair time charts also).
Product Code:
Example:
Product 50 = Frame;
Product 52 = Axles;
Product 53 = Gears etc.
Unit Code:
Figures three and four identify the ASSEMBLY within the PRODUCT
Example:
Product 50 = Frame;
Unit 01 = Chassis;
Unit 02 = Bumpers etc .
Sub-assembly Code:
Example:
Product 50 = Frame;
Unit 01 = Chassis;
Sub-assembly 40 = Chassis cross members etc.

MAIN SERVICING OPERATIONS TO BE PERFORMED ON VEHICLE ENGINE
!
On vehicles equipped with 8140.43B/R/S (Common Rail) engines, follow the indications specified below before
performing engine servicing operations that involve fuel system:
- before every engine servicing operation, perform engine/vehicle diagnosis by proper IVECO testers and print out
obtained results.
- MS6.3 control unit replacement shall be authorised by Help Desk.
- The following fuel system components shall not be overhauled but replaced: flow control devices, pressure relief
valve, fuel pressure sensor, rail, complete CPI high pressure pump, pressure control valve, electroinjectors;
- Every Common Rail system part is packed by supplier into oil paper sheets and then stored into cardboard boxes.
These parts shall be protected against dampness and shall be unpacked just before their use.
- Take utmost care to part cleanliness during filter and prefilter handling and fitting (even in case of simple
replacement) to prevent foreign matters and dirt infiltration. To this purpose, hydraulic part and sensor protective
plugs shall be removed just before refitting into place.
- Assembly direction shall be observed for all electric connections.
- Every threaded connection shall be tightened to the specified torque.
- Every quick coupling connector (on this engine find them on high pressure pump and diesel fuel draining duct) shall
be fitted properly. Operate on the tabs set at connector base to remove them.
Electroinjector:
injector body connections/unions/nuts shall never be manipulated. Nozzle body and electromagnet shall never be
disassembled, since this operation is not required and is forbidden.
When servicing operations on high pressure pipe are required, the hexagon on injector side shall be held with proper
wrench.
Before servicing pipes, check whether injector is fitted into seat on cylinder head.
When removing/refitting injector draining duct, do not remove retaining spring from its seat on injector: when pushing
the spring towards the engine and exerting a vertical force on connector, recycling is released. When refitting, put
recycle connector into its seat and exert a vertical force by pressing the retaining spring towards engine. Fitting shall
be friendly.
Rev. sensor (camshaft/flywheel):
during positioning, air gap between sensor and phonic wheel shall be falling within 0.8 and 1.5 mm and detection surface
and wheel surface shall be parallel.
CPI high pressure pump:
it is forbidden to operate on pressure control or third pumping element cut-out device.
When servicing operations on high pressure pipe are required, the hexagon on pump side shall be held with proper
wrench.
Before servicing high pressure pipe, check whether pump is properly fitted into its seat.
High pressure pipes
When removed, high pressure pipes shall not be reused but replaced.
Fixing connection tightening or loosening shall be performed with injectors, rail and high pressure pump perfectly
secured and holding the hexagon on component side if there is enough space.
Rail and accessories
Pressure control device and pressure relief valve can be refitted 5 consecutive times, then they shall be replaced. Before
refitting they shall be smeared with an oil film.
Overpressure valve shall be lubricated before refitting and its seal shall always be replaced.
For engine 8140.43S only - Since engine No. 3089322, a rail with the same configuration but without flow limiters
and pressure relief valve has been mounted. The same prescriptions specified for the previous one shall be complied
with.

Removal (Engine 8140.43C - 8140.63)

- 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 bearing
(2, Figure 6) from diaphragm spring (3, Figure 6) by
opening circlip (4, Figure 6).
Fit thrust bearing (2, Figure 6) 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 (2, Figure 6) 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;
- fill the cooling system with coolant.
- 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.
- 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.

507130 OXICAT - OXYDIZER CATALYST
(Vehicles with 8140.43C -
8140.63 engines)
Description
455182
The oxidizing catalyst (1) is a post-treatment device for ex-
haust gases. It is used to oxidize CO, HC transforming them
into carbon dioxide (CO2) and steam (H2O).
This catalyst also treats saturated and aromatic hydrocarbons
forming part of the particulate, such as the carbon in the form
of soot, metals, water and sulphur compounds that are ex-
hausted.
The cylindrical-shaped catalyst consists of a ceramic honey-
comb monolith whose cells are platinum-impregnated, a ca-
talyzing substance of oxidation reactions. Its total volumetric
capacity is equal to 600 cm3 with a density of 400 cells per
square inch.
The exhaust gases passing through the cells heat the catalyst,
converting the pollutants into inert compounds.
The chemical oxidation reaction of CO, HC and of the parti-
culate is efficient with temperatures ranging between
200°C ÷350°C.
With temperatures higher than 350°C it starts oxidizing the sul-
phur contained in the diesel oil, generating sulphur dioxide
(SO2) and sulphur trioxide (SO3), which are the cause of acid
rain.
Correct catalyst sizing enables limiting the temperature, ob-
taining the greatest percentage of conversion of polluting
emissions, while reducing the freezing of sulphur compounds.
Check the level of oil in the tank and top it up if necessary.
Lift the vehicle at the front, start up the engine and let it idle
for some time.
Check there is no oil leakage from the hydraulic circuit and
check the level in the tank.
Slowly turn the flywheel in both directions of steering so that
the air in the hydraulic system comes out.
Check the level of oil in the tank again and top up if necessary.
