Engines Iveco C87 / Cursor 87. Instruction - page 1

Manuals for repairs are split into Parts and Sections, each one of which is marked by a numeral; the contents of these sections are
indicated in the general table of contents.
The sections dealing with things mechanic introduce the specifications, tightening torque values, tool lists, assembly
detaching/reattaching operations, bench overhauling operations, diagnosis procedures and maintenance schedules.
The sections (or parts) of the electric/electronic system include the descriptions of the electric network and the assembly’s
electronic systems, wiring diagrams, electric features of components, component coding and the diagnosis procedures for the
control units peculiar to the electric system.
Section 1 describes the engines illustrating its features and working in general.
Section 2 describes the type of fuel feed.
Section 3 relates to the specific duty and is divided in four separate parts:
1. Mechanical part, related to the engine overhaul, limited to those components with different characteristics based on the relating
specific duty.
2. Electrical part, concerning wiring harness, electrical and electronic equipment with different characteristics based on the relating
specific duty.
3. Maintenance planning and specific overhaul.
4. Troubleshooting part dedicated to the operators who, being entitled to provide technical assistance, shall have simple and direct
instructions to identify the cause of the major inconveniences.
Sections 4 and 5 illustrate the overhaul operations of the engine overhaul on stand and the necessary equipment to execute such
operations.
The appendix contains a list of the general safety regulations to be respected by all installation and maintenance engineers in order
to prevent serious accidents taking place.
The manual uses proper symbols in its descriptions; the purpose of these symbols is to classify contained information. In particular,
there have been defined a set of symbols to classify warnings and a set for assistance operations.

General danger
It includes the dangers of above described signals.

Danger of serious damage for the assembly
Failure to comply, both fully or in part, with such prescriptions will involve serious damage to the assembly and may
sometimes cause the warranty to become null and void.

Environment protection
Moreover, it describes the correct actions to be taken to ensure that the assembly is used in such a way so as to protect
the environment as much as possible.

Danger for persons
Missing or incomplete observance of these prescriptions can cause serious danger for persons’ safety.

GENERAL WARNINGS

Warnings shown cannot be representative of all danger situations possibly occurring. Therefore, it is suggested to contact
immediate superiors where a danger situation occurs which is not described.

Use both specific and general-purpose toolings according to the prescriptions contained in respective use and
maintenance handbooks. Check use state and suitability of tools not subjected to regular check.

The manual handling of loads must be assessed in advance because it also depends, besides weight, on its size and on
the path.

Handling by mechanical means must be with hoisters proper as for weight as well as for shape and volume. Hoisters,
ropes and hooks used must contain clear indications on maximum carrying capacity acceptable. The use of said means
is compulsorily permitted to authorised personnel only. Stay duly clear of the load, and, anyhow, never under it.

In disassembling operations, always observe provided prescriptions; prevent mechanical parts being taken out from
accidentally striking workshop personnel.

Workshop jobs performed in pairs must always be performed in maximum safety; avoid operations which could be
dangerous for the co-operator because of lack of visibility or of his/her not correct position.

Keep personnel not authorised to operations clear of working area.

You shall get familiar with the operating and safety instructions for the assembly prior to operating on the latter. Strictly
follow all the safety indications found on the assembly.

Do not leave the running assembly unattended when making repairs.

When carrying out work on the assembly lifted off the ground, verify that the assembly is firmly placed on its supporting
stands, and that the manual/automatic safety devices have been actuated in the event that the assembly is to be lifted
by means of a hoist.

When you have to operate on assemblies powered by natural gas, follow the instructions contained in the document,
as well as all the specific safety standards provided for.

Only remove radiator cap when the engine is cold by cautiously unscrewing it in order to let system residual pressure
out.

Inflammable fuel and all inflammable fluids and liquids must be handled with care, according to what contained on harmful
materials 12-point cards. Refuelling must be performed outdoors with the engine off, avoiding lit cigarettes, free flames
or sparks in order to prevent sudden fires/bursts. Adequately store inflammable, corrosive and polluting fluids and liquids
according to what provided by regulations in force. Compulsorily avoid to use food containers to store harmful liquids.
Avoid to drill or bore pressurised containers, and throw cloths impregnated with inflammable substances into suitable
containers.

Worn out, damaged or consumable parts must be replaced by original spares.

During workshop activity, always keep the work place clean; timely clear or clean floors from accidental liquid or oil spots.
Electric sockets and electric equipment necessary to perform repair interventions must meet safety rules.

Clean the assemblies and carefully verify that they are intact prior to overhauling. Tidy up detached or disassembled
parts with their securing elements (screws, nuts, etc.) into special containers.

Check for the integrity of the parts which prevent screws from being unscrewed: broken washers, dowels, clips, etc.
Self-locking nuts with an insert made of nylon must always be replaced.

Avoid contact of rubber parts with diesel oil, petrol or other not compatible substances.

Before washing under pressure mechanical parts, protect electric connectors, and central units, if present.

Tightening screws and nuts must always be according to prescriptions; FPT commercial and assistance network is
available to give all clarifications necessary to perform repair interventions not provided in this document.

Before welding:

- Disconnect all electronic central units, take power cable off battery positive terminal (connect it to chassis bonding)

and detach connectors.

- Remove paint by using proper solvents or paint removers and clean relevant surfices with soap and water.

- Await about 15 minutes before welding.

- Equip with suitable fire resistant protections to protect hoses or other components where fluids or other materials

flow which may catch fire easily on welding.

Should the vehicle be subjected to temperatures exceeding 80

°C (dryer ovens), disassemble drive electronic central

units.

The disposal of all liquids and fluids must be performed with full observance of specific rules in force.

Put on, where required by the intervention, garments and protections provided in accident prevention rules; contact
with moving parts can cause serious injuries. Use suitable, preferably tight-fitted garments, and avoid to use jewels,
scarves, etc.

Do not leave the engine in motion at workshop locations not provided with a pipe to scavenge exhaust gas outside.

Avoid to breathe fumes coming from heating or from paint welding because they can cause damages to health; operate
outdoors or in suitably ventilated areas. Put on proper inspirator if paint powder is present.

Avoid contact with hot water or steam coming from the engine, radiator and pipings because they could cause serious
burns. Avoid direct contact with liquids and fluids present in vehicle systems; where an accidental contact has occurred,
refer to 12-point cards for provisions to make.
