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 t oolings 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 t aken out from accidentally striking workshop personnel.
Workshop jobs performed in pairs must always be performed in maximum safety; avoid operations whic h could be dangerous for the co-operator because of lack of visibility or of his/her not c orrect position.

INTRODUCTION
G-Drive EU/2002/88/CE N SERIES
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 directcontact with liquids and fluids present in vehicle systems; where an accidental contact has occurred, refer to 12-point cards for provisions to make.
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 nu ts 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:
- Disc onnect all electronic central units, take power cable off battery positive terminal (connect it t o chassis
bonding) and detach con nectors.
- 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 o f all liquids and fluids must be performed with full observance of specific rules in force.

GENERALWARNINGS ON THE ELECTRIC SYSTEM
If an intervention has to be made on the electric/electronic system, disconnect batteries from the system; in this case,
!
always disconnect, as a first one, the chassis bonding cable from batteries negative terminal.
Before connecting the batteries to the system, make sure that the system is well isolated.
Disconnect the external recharging apparatus from the public utility network before taking apparatus pins off battery terminals.
Do not c ause sparks to be generated in checking if the circuit is energised.
Do not use a test lamp in checking circuit continuity, but only use proper control apparatuses.
Make sure that the electronic devices wiring harnesses (length, lead type, location, strapping, connection to screening braiding, bonding, etc.) comply with FPT system and are carefully recovered after repair or maintenance interventions.
Measurements in driveelectronic central units, plugged connections and electric connections to components can only be made on proper testing lines with special plugs and plug bushes. Never use improper means like wires, screwdrivers, clips and the like in order to avoid t he danger of causing a short c ircuit, as well as of damaging plugged connections, which would later cau se contact problems.
INTRODUCTION

To start up the engine, do not use fast chargers. Start up must only be performed with either separate batteries or special truck.
A wrong polarisation of supply voltage in drive electronic central un it s (for instance, a wrong polarisation of batteries) can cause them to be destroyed.
Disconnect the batteries from the system during their recharging with an external apparatus.
On connecting, only screw up connector (temperature sensors, pressure sensors etc.) nuts at prescribed tightening torque.
Before disconnecting the junction connector from an electronic central unit, isolate the system.
Do not directly supply electronic central units servo components at nominal vehicle voltage.
Cables must be arranged such as to result to be parallel to reference plane, i.e. as close as possible to chassis/body structure.
Once the interventionon the electric system has been completed, recoverconnectors and wiring harnessesaccording to original arrangement.
NOTE
Print P4D32N002 E Base - November 2008

Bonding and screening
Negative leads connected to a system bonded point must be both as short and possible and “star“-connected to each other, trying then to have their c entering tidily and properly made (Figure 1, re. M).
Further, following warnings are to be compulsorily observed for electronic components:
- Electronic central units must be connected to system bonding when they are provided with a metallic shell.
- Electronic c entral units negative cables must be connected both to a system bonding point such as the dashboard opening bonding (avoiding “serial“ or “chain“ connections), and t o battery negative terminal.
- Analog bonding (sensors), although not connected to battery negative system/terminal bonding, must have optimal isolation. Consequently, particularly considered must be parasitic resistances in lugs: oxidising, clinchin g defects, etc.
- Screened circuits braiding must only electrically contact the end towards the central unit entered by the signal (Figure 2).
- If junction connectors are present, unscreened section d, near them, must be as short as possible (Figure 2).
- Cables must be arranged such as to result to be parallel to reference plane, i.e. as close as possible to ch assis/body structure.

LUBRICATION
Lubrication by forced circulation is achieved through oil rotary expansion pump, placed in the front part of the basement, driven by the straight-tooth gear splined to the shaft’s bar hold.
From the pan, the lubrication oil flows to the driving shaft, to the camshaft and to the valve drive.
Figure 1
Lubrication involves the heat exchanger (2,3), the turboblower for turbocompressed versions, and for any compressed air system.
All these components may often vary according to the specific duty.

Description of operation
The main rotation components are the propeller shaft (1), timing gear rotor (2), transfer pump vanes (3) and the regulator (8). Referring to Figure 2, the propeller shaft engages th e timing gear rotor inside the hydraulic head.
The four pistons are actuated t owards each other simultaneously by the int ernal ring of the cam via the rollers and sliding blocks that are conveyed in the holes on the end portion of the rotor.
The number of cam lobes is equal to that of the engine cylinders.
The transfer pump on the rear of the rotor is the positive displacement type and is closed inside the end plug. The en d plug also contains the inlet filter screen and the pressure regulator of the transfer pump. The top of the regulator assembly is pressed against the timing gear rotor and forms an end seal for the transfer pump.
The timing gear rotor contains two inlet ports, a single axial hole and a discharge port serving all the outlets to the injection lines.
The hydraulic head contains the hole in which the rotor turns, the h ole of the metering valve, inlet opening and the unions for the delivery ou t let. The high pressure injection lines that are connected to the injectors are secured to the above-mentioned outlet unions.

PASSAGE FROM 50 HZ TO 60 HZ FOR NEF MOTORS WITH STANADYNE PUMP
Figure 153
According to the specific needs of the motor employment it is possible that a request to vary the adjustment of the Stanadyne pump be made to obtain a different use frequency:
- 500rpm/50Hz
- 800rpm/60Hz
The necessary procedures will be described in order to execute the following adjustments:
- passage from 50 Hz to 60 Hz and vice versa.
- stabilizing of th e rotation regime.
NOTE
If only the Stanadyne identification tag (2) is present, this means that the injection pump presents a setting of 50 Hz. In case of modification of the setting from 50 Hz to 60 Hz done in the factory, an identification tag (1) is applied by FPT.
116400
On the FPT tag (I) reported are:
- the model of the injection pump (4);
- an identification code (3) of the specific application of
the setting of the injection pump, for example: A.S. 7.54 identifies the setting at 1800 rpm of 60 Hz.
Passage from 50 Hz to 60 Hz
To carry out the passage from 50 Hz to 60 Hz you must, first of all:
- identify the code of the injection pump from th e
Stanadyne tag (2).

NOTE
In case of doubt you can always unscrew the droop setting register screw (2) counterclockwise till you get to the final position - do not force it further in order to not damage the adjustment system.

If, for example, for a motor with an injection pump with code DB 4429 - 5945, o riginally set at 50 Hz, you want to pass to 60 Hz, it is sufficient to act on the droop setting adjustment screw (2) rotating it 3 times cloc kwise from the position in which it is, start the motor, loosen the adjustment screw of the maximum regime and accelerate with the accelerator lever, till yo u obtain the empty rotation regime equal to 62 Hz (l860 rpm),
- Then regulate the screw of the minimum regime (4) so
to block the accelerator lever in the newly obtained position and finally block both adjustment screws (I and
4) using the appropriate lock nuts (tightening torque 3,5 ÷ 4 Nm).
NOTE
- After starting the motor you must operate the maximum
(I) and minimum (4) register screws in order to block the accelerator lever (3) in the position to obtain the desired regime, considering the frequency fall in the passage from empty to full of the motor (about 2 Hz).
Print P4D32N002 E Base - November 2008
The adjustment screw of the minimum regime (4) does n ot allow the attainment of the minimum intended in the ”classical” meaning of the term because the injection pump regulator imposes a superior rotation regime since it is about an injection pump for the application of a generator

Stabilization of the rotation regime
In case of instability of the rotation regime, ac t on the droop setting adjustment screw (2, Figure 5) rotating lightly the same clockwise/counterclockwise till the stabilization of the motor rotation regime
NOTE
Attention! Some motors cannot undergo the passage from 50 Hz to 60 Hz and vic e versa, as they need a specific injection pump to work at the required regimes. Make reference to the SI 191 1 ”Service Information” to verify which motors cannot undergo the passage from 50 Hz to 60 Hz and vice versa.
