SAFETY AND WARNING DECALS - SAFETY INSTRUCTIONS
SAFETY AND WARNING DECALS
DANGER
CAUTION
Failure to comply with the instructions could result in damage to
persons and property
Failure to comply with the instructions could lead to technical
damage to the machine and/or
system
SAFETY INSTRUCTIONS
• Lombardini Engines are built to supply their performances in a safe and long-lasting way. To obtain these results,
it is essential for users to comply with the servicing instructions given in the relative manual along with the safety
recommendations listed below.
• The engine has been made according to a machine manufacturer's specifications and all actions required to meet
the essential safety and health safeguarding requisites have been taken, as prescribed by the current laws in merit.
All uses of the engine beyond those specifically established cannot therefore be considered as conforming to the
use defined by Lombardini which thus declines all liability for any accidents deriving from such operations.
• The following indications are dedicated to the user of the machine in order to reduce or eliminate risks concerning
engine operation in particular, along with the relative routine maintenance work.
• The user must read these instructions carefully and become familiar with the operations described. Failure to do
this could lead to serious danger for his personal safety and health and that of any persons who may be in the
vicinity of the machine.
• The engine may only be used or assembled on a machine by technicians who are adequately trained about its
operation and the deriving dangers. This condition is also essential when it comes to routine and, above all,
extraordinary maintenance operations which, in the latter case, must only be carried out by persons specifically
trained by Lombardini and who work in compliance with the existing documentation.
• Variations to the functional parameters of the engine, adjustments to the fuel flow rate and rotation speed, removal
of seals, demounting and refitting of parts not described in the operation and maintenance manual by unauthorized personnel shall relieve Lombardini from all and every liability for deriving accidents or for failure to comply
with the laws in merit.
• On starting, make sure that the engine is as horizontal as possible, unless the machine specifications differ. In
the case of manual start-ups, make sure that the relative actions can take place without the risk of hitting walls
or dangerous objects, also considering the movements made by the operator. Pull-starting with a free cord (thus
excluding self-winding starting only), is not permitted even in an emergency.
• Make sure that the machine is stable to prevent the risk of overturning.
• Become familiar with how to adjust the rotation speed and stop the engine.
• Never start the engine in a closed place or where there is insufficient ventilation. Combustion creates carbon
monoxide, an odourless and highly poisonous gas. Lengthy stays in places where the engine freely exhausts this
gas can lead to unconsciousness and death.

SAFETY AND WARNING DECALS - SAFETY INSTRUCTIONS
• The engine must not operate in places containing inflammable materials, in explosive atmospheres, where there is
dust that can easily catch fire unles specific, adequate and clearly indicated precautions have been taken and have
been certified for the machine.
• To prevent fire hazards, always keep the machine at least one meter from buildings or from other machinery.
• Children and animals must be kept at a due distance from operating machines in order to prevent hazards deriving from their operation.
• Fuel is inflammable. The tank must only be filled when the engine is off. Thoroughly dry any spilt fuel and move
the fuel container away along with any rags soaked in fuel or oil. Make sure that no soundproofing panels made
of porous material are soaked in fuel or oil. Make sure that the ground or floor on which the machine is standing
has not soaked up any fuel or oil.
• Fully tighten the tank plug each time after refuelling. Do not fill the tank right to the top but leave an adequate space for the fuel to expand.
• Fuel vapour is highly toxic. Only refuel outdoors or in a well ventilated place.
• Do not smoke or use naked flames when refuelling.
• The engine must be started in compliance with the specific instructions in the operation manual of the engine and/
or machine itself. Do not use auxiliary starting aids that were not installed on the original machine (e.g. Startpilot’).
• Before starting, remove any tools that were used to service the engine and/or machine. Make sure that all guards
have been refitted.
• During operation, the surface of the engine can become dangerously hot. Avoid touching the exhaust system in
particular.
• Before proceeding with any operation on the engine, stop it and allow it to cool. Never carry out any operation
whilst the engine is running.
• The coolant fluid circuit is under pressure. Never carry out any inspections until the engine has cooled and even in
this case, only open the radiator plug or expansion chamber with the utmost caution, wearing protective garments
and goggles. If there is an electric fan, do not approach the engine whilst it is still hot as the fan could also start
operating when the engine is at a standstill. Only clean the coolant system when the engine is at a standstill.
• When cleaning the oil-cooled air filter, make sure that the old oil is disposed of in the correct way in order to safeguard the environment. The spongy filtering material in oil-cooled air filters must not be soaked in oil. The reservoir of the separator pre-filter must not be filled with oil.
• The oil must be drained whilst the engine is hot (oil T ~ 80°C). Particular care is required to prevent burns. Do not
allow the oil to come into contact with the skin.
• Make sure that the drained oil, the oil filter and the oil it contains are disposed of in the correct way in order to safeguard the environment.
• Pay attention to the temperature of the oil filter when the filter itself is replaced.
• Only check, top up and change the coolant fluid when the engine is off and cold. Take care to prevent fluids containing nitrites from being mixed with others that do not contain these substances since "Nitrosamine", dangerous
for the health, can form. The coolant fluid is polluting and must therefore be disposed of in the correct way to safeguard the environment.
• During operations that involve access to moving parts of the engine and/or removal of rotating guards, disconnect
and insulate the positive wire of the battery to prevent accidental short-circuits and to stop the starter motor from
being energized.
• Only check belt tension when the engine is off.
• Only use the eyebolts installed by Lombardini to move the engine. These lifting points are not suitable for the entire machine; in this case, the eyebolts installed by the manufacturer should be used.

COOLING SYSTEM
COOLING SYSTEM DESCRIPTION
The engine cooling is carryed out by means of air blown by the centrifugal fan, attached on the flywheel, on the cylinder head
unit .
The heat is removed from the cylinder and cylinder head through the appropriate finning of themself. Moreover, particularly in the
cylinder head area, close to the exaust valve seat and to the pre-combustion chamber, the heat is removed by the lubrication oil,
as previously described in the chapter relative to the lubrication system. When the engine is cold, because of high oil pressure
due to the high viscosity, a by-pass valve limits the oil quantity sent to the area to be cooled.

LUBRICATION SYSTEM DESCRIPTION
The oil contained in the engine sump is deaerated through the labyrinth (1) and filtered by the filter (2) before it is sucked by the
pump (3) through the suction duct (4).
From the pump the oil is pushed towards a circuit machined in the cylinder head in proximity to particular points to be cooled
(5).
The cooling circuit internal pressure is limited by the by-pass valve (7). The by-pass valve is necessary because, with the engine
cold and therefore with high oil viscosity the oil pressure wouldbecome too high. The diaphragm (6) regulates the oil quantity
for the camshaft lubrication.
A by-pass valve (8) regulate the lubrication pressure at a predetermined value. Before being sent to the cylinder head (5),
to camshaft support (9) and to the journal bearings (10) the oil is filtered through a total flow filter cartridge (11). In case of
obstruction of the filter an internal by-pass valve (12) opens up.
Nearby on the clutch side crankshaft support, a nozzle with a closing valve is fixed. These nozzle valve is preset and has the
function of cooling the piston through its oil jet and to lubricate the connecting rod small end bearing and the piston pin.
The oil that comes out from the cylinder head and camshaft carrier compartment is returned into the crankcase through an
appropriate pipe that is not represented in the figure.

FUEL FLOW GOVERNOR DESCRIPTION
From figures 1 and 2 one can see the essential components and the functioning of the governor.
The mass holder (1) is driven in rotation by its own shaft driven in turn by the camshaft.
In to the mass holder (1) there are 4 centrifugal counterweights (2) that act on the push rod (3) . The push rod activate's the
lever (4) hinged on the pivot (5) which is fixed to the governor housing, the other end of the lever links to the injection pump
regulation rod (7) .
Between the lever (6) and the lever (4) acts a spring (8) for the starting maximum fuel flow. On the control lever (6) acts : the
spring (9) for the idle-speed control ; the spring (20) for the adjust of the fuel flow to the engine rpm ; and through the cup (10)
and the shaft (11) , the maximum engine rpm control spring (12). The last spring , assembled with pre-load in the frame (17) ,
is futter compressed by the lever (13) which is connected with the speed control lever (14).
The lever (15) , which is connected to the engine stop control (16) , acts on the lever (4) and then on the injection pump control
rod (7). On the governor box a magnet (18) is fixed , its function is to keep the lever (4) in the position of supplementary flow at
the engine start position. The lever (6) pushcs on the regulation screw (19) that puts in a correct position the rod (7).
Magneto positioning on the governor
Insert the injection pump on the cylinder head and lock it after positioning in may del position.
Loosen the magneto fixing screws and move the magneto itself in order to meet the push rod lever; fix the magneto in this
position and check that the release load of the push rod lever is 700 ÷ 800 gr.
Engine stop lever adjustment
Running position: adjust the catch screw (20) of the engine stop lever (16), in such a way that it’s internal part does not
interfere with the rod control lever (4).
Stop position: adjust the stop screw (21) of the engine stop lever (16), in such a way that the stop does not take place through
the rod control lever (4) and the connection rod (7), on the injection pump

GOVERNOR'S WORKING DESCRIPTION
ENGINE STANDING OR AT STARTING
In these conditions the governor flyweight are completely closed, due to the slider thrust on which acts the minimum and the
extra-fuel springs (see fig. 3) . The control lever, pushed at one end by the minimum spring, reacts on the regulation screw.
The control rod lever, pushed by the relative extra-fuel spring, puts the pump control rod in the maximum fuel flow position and
therefore in the engine start position. Notice that acting on the accelerator lever there will not be any effect on the pump control
rod because the control lever is already in contact with the regulation screw ; so this mean that you can start the engine with the
accelerator at the minimum position.
The magnet, with the help of the supplementary spring, keep in the maximum fuel flow position the control rod until the engine
has not reached about 2000 rpm.
When the engine exceed 2000 rpm the flyweight centrifugal force exceed the spring and magnet force, so open the flyweight that
shift by means of the slider i the control rod lever and then the pump connecting rod i to lower fuel flow positions.
ENGINE AT IDLE SPEED
After the starting of the engine, if someone does not act on the accelerator lever, the governor flyweight are in equilibrium with the
minimum spring at about 1200 rpm. The engine speed increasingly open the flyweight moving the slider , the regulation lever
until the system do not reach a new equilibrium position; at the same time the pump connecting rod is moved to lower fuel flow
positions, for this reason the engine comes back to the initial speed. The opposite happens if the engine reduce the speed. With
the engine at idle speed the governor will fluctuate continuously around the equilibrium position in order to maintain the speed
as constant as possible.

ENGINE AT PARTIAL LOAD
From the minimum position, by acting on the accelerator lever, the minimum spring is completely pre-loaded; after that, the cup.
Is push directly on the regulation lever carrying the pump connection rod toward greater fuel flow positions partially closing the
governor flyweight. In this situation the injection pump flow regulation rod acts as if it is directly connected to the accelerator
lever, that means that the movements of the accelerator lever produce proportional mouvements of the pump connection rod.
At intermediate engine speed, the governor generate a load that compress partially the flow adjusting spring moving the rod
control lever, producing consequently change of the pump flow against change of rpm.
ENGINE AT FULL LOAD
Moving completely the accelerator lever until the position of full load, the lever will touch the regulation screw, after that the
maximum rpm regulation spring will be compressed. Starting from low speed, when the speed increases, the governor flyweights
centrifugal load compress the flow adjust spring, proportionally reducing the pump fuel flow.
This is the wasking position of the pump connecting rod for maximum fuel flow .

ENGINE AT MAX SPEED
When the engine reaches the maximum working speed the governor flyweights centrifugal force exceede the reaction of the
maximum speed regulating spring; the expanding flyweights move the regulating lever and the pump connecting rod towards a
position of lower fuel flow.
If the engine continues to accelerate the flyweights continue to move until the pump connecting rod reaches the position of zero
flow. The governor begins to operate at about 3800 rpm and the zero fuel flow occures at about 4200 rpm.

Injector setting
Connect injector to a hand pump and check that setting pressure is
150 +10 - 0 bar; Make the required adjustments, if any, by changing
the shim over the spring. Eleven different shims are available as spares
with size from 1 to 2 mm.
When replacing the spring, setting should be performed at a 10 bar
greater pressure(160 bar) to allow for bedding during operation.
Check needle valve sealing by slowly moving the hand pump until approximately 120 bar for 10 seconds.
Injector sealing
Seal: Keep inside injector a oil pressure 10÷20 kg/cm2 lower than the
opening pressure.No drop should form on the end of the injector in less
than 10 seconds.However a light sweating is allowed.
Caution - The injector jet, because of high output pressure car cause
wounds whose consequences can be very serious. Take care that
during the tests the jet itself doesn’t hit any part of the body.

Valves grinding
Carefully remove carbon deposit without notching the metal and wash
with cleaning liquid.
Inspect valves seats: they shouldn’t present indentations or scorings,
but they must have a uniform surface so as to assure a perfect valve
seal. Otherwise carry out valves seat grinding. This operation must be
performed as follows with the best attention: smear valves with fine
emery, introduce the valve in its guide and fix wrench “O” to the stem
end. Alternately maneuver the wrench by changing, from time to time,
position.
Absolutely avoid that emery is introduced into valves guides. When the
operation has been carried out carefully wash and blow cylinder head
and valves. For the checking of the perfect seal of valves pour some
gasoline (petrol) into admission and exhaust ducts, then check that
gasoline (petrol) doesn't flow through valves themselves.
O
154
N.B. - If valves seats are worn or with deep indentations it is necessary,
before carrying out the grinding, to perform on the valves seats with
proper milling cutters.
Reassembly of valves
R
Prior to valve reassembling, which is done in reverse sequence as to disassembling,
always replace the two sealing rings on the valve guides using punch 986290.109. Important - Before reassembling valves lubricate guides and stems.

Precombustion chamber – disassembly and reassembly
To extract the precombustion chamber, top the injector seat with a purch (Fig. 159) from the injector seat.This expulsion method
causes damages to the precombustion chamber, therefore it must be replaced every time it is extracted.Before assembling the
new precombustion chamber, the depth of the seat inside the head shall be measured (Fig. 160÷161); the resulting measurement
will determine the most appropriate precombustion chamber of the four of different height that are available.In order to identify
them, each precombustion chamber is marked with a paint brush-stroke in different colors according to its height (as indicated in
the table).The precombustion chamber shall be inserted into the seat so that the dowel 1 coincides with the appropriate seat 2.
The interference between the precombustion chamber external diameter and the seat internal diameter shall be 0.01÷0.05.
The precombustion chamber housing shall conform to the specifications shown in the related table with respect to the head
surface.

Oil pump gear and oil pump - reassembling
When reassembling the oil pump, always replace the seal with a new one.
Reassemble the oil pump paying attention to the correct assembly direction (suction and delivery). We advise you to fill the pump
case with oil before the assembly.
Before and after final tightening the two fastening bolts “A” of the pump case to the housing half, check that the pump turns freely
by rotating the shaft manually 4 or 5 times. The two bolts “A” are tightened to an 8 Nm torque.
Reassemble the chain after attaching it by using the oil pump control gear. The bolt fastening the gear to the oil pump shaft shall
be tightened to a 10÷12 Nm torque.
Oil pump pressure check
The oil pressure check shall be performed with the oil at a temperature of 100° C.

Description of the injection advance regulator
When starting, and at a low idling speed the correct value of injection advance
is 11° before P.M.S..
This value increases in accordance with the engine RPM, attains 24° at
3500 R.P.M., then renains constant.
The advance variation is obtained through the injection advance regulator,
see fig. 270.
It consists of the flange A splined to the camshaft and the carrier, both with
the fulcrum on two pins, of the centrifugal weights C; of a counterflange F,
integral with the injection cam and free to rotate on the camshaft, on which
two slots are made where the pins D connected to the centrifugal weights
slide.
Appropriate springs B are applied between the centrifugal weights C and
the flange A.
270
With the engine stopped and at low idling speed the spring load is higher than
the weights centrifugal force, therefore they remain closed, see fig. 271.
271
When the RPM increases, the centrifugal weights force becomes higher
than the spring load, the weights move and through the pins D engaged
into the slots rotating the injection cam.
At 3500 R.P.M. the weights are completely open, see fig. 272 and the
injection advance is 24° before P.M.S.

Check of tappets clearance
Rotate the engine and put the piston at T.D.C. in compression stroke. With a thickness gauge check that tappets clearance is
0.30 mm for inlet valve and 0.40 mm for the exhaust valve, with the engine cold.
If such a clearance doesn’t occur act as follows:
1) Rotate backwards the engine about 40° (to avoid the stroke of valves manual lowering and the hittling of valves against the
piston). Rotate the tappets so as to position cuts “A” on the upper part to make easier caps removal.
2) Insert tool 981075.424 between suction valve cap and camshaft and push so as to compress the tappet. Insert part 2 to
hold the tappet and extract part 1.
3) Undermine the cap by using a shin point, remove it and replace with another one with a suitable dimension. As spares 28
caps from 3.25 mm. up to 4,60 mm. are pointed out on this page.
Important - The value of the cap appears on one of the surfaces of the cap itself, which on assembly must face the tappet.
Make sure that the real thickness of the cap correspond to the recommended value.

INJECTION EQUIPMENT DESCRIPTION AND FUNTIONING
FUEL INJECTION
In the Diesel engine the fuel is injected towards the end of the compression process into the precombustion chamber via the
injection pump and relative injector.
The quantity of fuel injected for each cycle is regulated by a function of the power/capacity required through the rotation of the
pumping element of the injection pump that is carried out by the regulation rod.
FUEL FLOW CONTROL
The regulation rod is set into action by the governor. The governor is connected to the upper part of the engine and is driven by
a shaft connected with the camshaft.
- engine idle speed control
- to limit engine maximum rpm
- to increase fuel flow at the engine starting.
The principal functions of the governor are :
Adjustment of pump control rod
In case of engine overhauling or interventions on delivery control it is necessary to check the position of injection pump control
rod and if necessary carry out the adjustment as follows: fit dial gauge on tool 981075.423, insert ring 984070.499 on tool
making sure that pin "R"seats in its concerning slot; let tool reference 984070.499 hole match with the one of the ring; insert
punch “A” and set to zero dial gauge. Take away the ring "A" and fit the tool on the place of the injection pump making sure that pin “R” of tool is inserted into the
hole of pump control rod, then fit reference punch “A” and lock the tool with both nuts.
Place lever “B” of accelerator to max. position and check that dial gauge is on the previously carried out zero setting position.
If these conditions do not occur act on adjusting screw “Z” until such zero setting is realized.Lock, by holding the screw “Z”
steady, lock-nut “V” and check by placing more times lever “B” to max position, that the dial gauge result is set to zero.
Warning - The mentioned checking operations must be carried out without injection pump control tappet.

Injection pump and check static injection advance
Insert the tappet in its housing equipped with cap, position the shims and the injection pump making sure, before the locking,
that pin is correctly inserted into the control rod and reference dowel into its housing.
286
287
288
Then check injection advance tining as follows.
1) Connect delivery pipe “C” of the proper hand pump (for
inst. BOSCH Type) to the feed union of injection pump and
insert suction pipe into a container filtered and full of gas
oil and plug the hole of gas oil recovery “D” by means of a
threaded plug.
2) Rotate the engine so as A.I.D. (dynamic injection
advance) reference mark coincide on clutch cover
(compression stroke).
3) Operate hand pump and bleed the circuit by means of
plug on hole “D”, previously fitted. Then exert pressure on
the gas oil so as it comes out from injection union “F”.
4) Fit a transparent pipe “H” on union “F”. Operate again the
pump and at the some time rotate the engine towards T.D.C.
up the point where the climbing of gas oil in the transparent
hose doesn’t cease. Timing is correct if in such a point
reference mark the clutch is aligned to A.I.S mark (static
injection advance 11° before T.D.C.).
If the engine results are advanced or retarded replace the
shins below the injection pump (as spares to this aim two
packings of 0.2 mm and 0.3 mm are supplied) or fit more
packings according to need. Bear in mind that by increasing
0.1 mm. the packing we obtain a retard of 1° and by
reducing 0.1 mm the packing we have 1° in advance.
289
N.B. - In order to be certain of the correct timing of injection
advance repeat more times the test carried out on the point
4.

Injection advance dynamic control
The dynamic control of the injection advance is made through a
suitable equipment - stroboscopic gun - according to the following:
1) Clean carefully the injection pipe and check that the sensor
coupling zone “V” is free from scoring signs
2) Install the sensor “V” of tester, paying attention not to turn it after
fastening. Connect the tester supply cable as shown in fig. 311
3) Start and heat the engine. With the engine idling at 1200 rpm, use
the button on the stroboscopic gun to make path “S” on the clutch
flywheel coincide with path “T” of TDC on the clutch cover. Check
that the advance read on the tester display is 13°.
Increase rpm rating gradually and check that at 3200 - 3500 rpm
the advance gradually increased reaches 26° If the range is lower
than the one provided, it is necessary to overhaul the advance
variator.
