When working on the engine, for example when adjusting drive belts and the clutch, or when changing the
oil, it is important not to start the engine. The engine could be damaged, but more importantly there is a
serious risk of injury.
For this reason, always secure the starting device or disconnect a battery cable before working on the engine.
This is especially important if the engine has a remote starter or automatic starting.
This warning symbol and text can be found next to those inspection points where it is particularly important
to bear in mind the risk of injury.

This Operator's Manual describes the operation
and inspection of Scania industrial engines.
The engines are direct-injection, liquid-cooled,
four-stroke, turbocharged diesel engines. Certain
engines are also equipped with an SCR system
for emission control.
The engines are available with different output
and engine speed settings. The normal output
setting of the engine (performance code) is indicated on the engine data plate.
Only standard components are described in the
operator's manual. Information about special
equipment is contained in instructions from the
various manufacturers.
Introduction
To ensure the maximum performance and the
longest service life for the engine remember the
following:
•Read through the Operator's Manual before
starting to use the engine. Even regular users
of Scania engines will get new information
from the Operator's Manual.
•Always follow the inspection instructions.
•Read the section on safety carefully.
•Get to know your engine so that you know
what it can do and how it works.
•Always contact a workshop with qualified
personnel for inspection and repair.
The information in this manual was correct at the
time of going to press. Scania reserves the right
to make alterations without prior notice.
Scania develops and produces engines that are as
environmentally-friendly as possible. Scania has
made major investments in the reduction of
harmful exhaust emissions in order to fulfil the
environmental requirements in force in almost
every market.
At the same time, we have been able to maintain
a high level of performance and operating economy for Scania Industrial and Marine Engines.
To maintain these throughout the entire service
life of the engine, it is important for the user to
follow the instructions on running, inspection
and fuel and lubricating oil as outlined in the Operator's Manual.
Other green initiatives taken include ensuring
that, following inspection and repair, waste that
is harmful to the environment (for example oil,
fuel, coolant, filters and batteries) is disposed of
accordance with the applicable environmental
requirements.
Safety
Different types of advisory
Warning!
All advisories preceded by Warning! are very
important. They warn of serious faults and incorrect operation that could lead to personal injury.
Example:
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
Important!
Advisories preceded by Important! warn of
faults and incorrect operation that could lead to
equipment being damaged. Example:
For Scania to guarantee that the engine corresponds to its certified configuration, and take responsibility for any damage and injuries that
occur, inspection must be carried out as above.
The following pages contain a summary of the
safety precautions to be complied with when operating and inspecting Scania engines. The
equivalent text can also be found under the relevant inspection point.
To prevent damage to the engine and to ensure
that it runs optimally, follow the instructions in
the warnings and advisories.
If the instructions are not followed, the warranty
can cease to apply.
Property of American Airlines
Note:
Advisories preceded by Note: refer to information important to ensure the best possible operation and functionality. Example:
Leave the engine off for at least 1 minute before
checking the oil level.
Environment
This Operator’s Manual contains specially highlighted text with instructions to help protect the
environment during inspection. Example:
•in the vicinity of flammable or explosive material, e.g. fuel, oils, batteries, chemicals
•when refuelling and in the vicinity of the filling station
•when working on the fuel system
Safety precautions for running the
engine
Daily inspection
Always carry out a visual inspection of the engine and engine compartment before starting the
engine or when the engine has been switched off
after operation.
Refuelling
Never overfill the fuel tank as the fuel needs
space to expand. Also ensure that the filler cap is
properly closed.
During refuelling there is a risk of fire and explosion. The engine must be switched off and smoking is prohibited.
Hazardous gases
Only start the engine in a well ventilated area.
The exhaust gases contain carbon monoxide and
nitrogen oxides, which are toxic.
If it is run in an enclosed space, there should be
an effective device to extract exhaust gases and
crankcase gases.
This inspection should be done to detect fuel, oil
or coolant leaks, or anything else that may require corrective action.
Fuel
Use only fuel recommended in the workshop
manual.
The wrong fuel grade can cause breakdowns or
stoppages by causing the injection system to
malfunction. This can cause damage to the engine and, possibly, personal injury.
Property of American Airlines
Starter lock
If the control panel is not fitted with a starter
lock, the engine compartment should be locked
to prevent unauthorised personnel from starting
the engine. Alternatively, a lockable master
switch or battery master switch can be used.
Never use starter gas or similar agents to help
start the engine. This can cause an explosion in
the intake manifold and possible injury.
Running
The engine must not be run in environments
where there is a risk of explosion, as all of the
electrical or mechanical components can generate sparks.
Approaching a running engine always poses a
safety risk. Parts of the body, clothes or dropped
tools can get caught in rotating parts such as the
fan and cause injury. For personal safety all rotating parts and hot surfaces must be fitted with
guards.
Batteries
The batteries contain and form oxyhydrogen gas,
particularly during charging. Oxyhydrogen gas
is flammable and highly explosive.
There must be no smoking, naked flames or
sparks near the batteries or the battery compartment. Incorrect connection of a battery cable or
jump lead can cause a spark, which can cause the
battery to explode.
Chemicals
Most chemicals such as glycol, anti-corrosive
agents, preservative oils and degreasing agents,
are hazardous to health.
Some chemicals, such as preservative oil, are
also flammable.
Safety precautions for handling materials
Fuel and lubricating oil
All fuels and lubricants as well as many chemicals are flammable. Always follow the instructions on the relevant packaging.
The work must be carried out on a cold engine.
Fuel leaks and spillage on hot surfaces can cause
fire.
Store used rags and other flammable materials
safely so as to avoid spontaneous combustion.
Property of American Airlines
Always follow the safety precautions on the relevant packaging.
Store chemicals and other materials which are
hazardous to health in approved containers,
marking them clearly and storing them where
they are inaccessible to unauthorised persons.
Always hand in leftover and used chemicals to
an authorised waste disposal contractor.
Reductant (AdBlue/DEF) is used in the reductant
tank on engines equipped with an SCR system.
Avoid contact with the skin.
If reductant comes in contact with the skin: Wash
with soap and plenty of water. If reductant
splashes in the eyes: Rinse immediately with
plenty of water. Contact a doctor if it is ingested
or causes skin irritations.
Safety precautions for inspection
and repair
Switch off the engine
Always switch off the engine before carrying out
inspections and repairs, unless otherwise indicated.
Hot surfaces and fluids
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are exhaust manifolds, turbochargers, oil sumps, hot
coolant and oil in pipes and hoses.
Lift the engine out
Always use the engine lifting eyes. Always
check that lifting devices are in good condition
and are designed to lift the weight.
Optional equipment on the engine can change
the centre of gravity. This means that it may be
necessary to use additional lifting devices to balance the engine correctly and lift it safely.
Make it impossible to start the engine: Remove
any starter key, or cut the power using the main
power switch or battery master switch and lock
them.
Fix a warning plate somewhere appropriate,
showing that work is being carried out on the engine.
Working with a running engine always poses a
safety risk. Parts of the body, clothes or dropped
tools can get caught in rotating parts and cause
injury.
The batteries contain highly corrosive sulphuric
acid. Take care to protect your eyes, skin and
clothes when charging or handling batteries.
Wear protective gloves and goggles.
If sulphuric acid comes in contact with the skin:
Wash with soap and plenty of water. If it gets in
your eyes: Rinse immediately with plenty of water and seek medical attention.
Always hand in used batteries to an authorised
waste disposal contractor.
Electrical system
Electric welding
When carrying out welding work on and near the
engine, disconnect the battery and alternator
leads. Pull out the multi-pin connector for the engine control unit as well.
Connect the welding clamp close to the component to be welded. The welding clamp must not
be connected to the engine, or so that the current
can cross a bearing.
When welding is finished:
1.
Connect the alternator and control unit cables first.
2.
Then connect the batteries.
Lubrication system
The engine must be switched off and the power
disconnected using the master switch or battery
master switch before working on the electrical
system. External power supplies to extra equipment on the engine must also be disconnected.
Scania recommends that Scania spare parts are
used for the fuel and electrical systems. Scania
spare parts are designed to minimise the risk of
fire and explosion.
Property of American Airlines
Hot oil can cause burns and skin irritation. Wear
protective gloves and goggles when changing
hot oil.
Make sure that there is no pressure in the lubrication system before starting work on it.
The oil filler cap must always be in place when
starting and running the engine to prevent oil being ejected.
Always hand in used oil to an authorised waste
disposal contractor.
Never open the coolant filler cap when the engine is hot. Hot coolant and steam may spray out
and cause burns.
If the cap has to be opened do it slowly and carefully to release the pressure before removing the
cap. Wear gloves as the coolant is still very hot.
Always hand in used coolant to an authorised
waste disposal contractor.
Environment and safety
Fuel system
Always wear protective goggles when testing injectors. Fuel escaping at high pressure can penetrate tissues and cause serious injury.
Scania recommends that Scania spare parts are
used for the fuel and electrical systems. Scania
spare parts are designed to minimise the risk of
fire and explosion.
Before starting
Ensure that all guards are in place before starting
the engine. Ensure that no tools or other objects
have been left on the engine.
The air filter must be fitted before starting the engine. Otherwise there is a risk of objects being
sucked into the compressor impeller or of injury
if you come into contact with the air filter.
An emissions certified engine fulfils the emissions requirements for a particular range of application.
On each emissions certified engine there is a label which shows which requirements the engine
fulfils. Scania guarantees that each such engine
fulfils the emissions requirements for the range
of application for which it is certified.
The following are required for the certified engine to fulfil the emissions requirements once it
has been taken into service:
•Inspection is to be carried out in accordance
with the instructions in this Operator's Manual.
•The inspection and repair of injection equipment are to be carried out by a qualified
workshop or person.
•The engine may only be modified with equipment that has been approved by Scania.
•Seals may be broken and setting data edited
only once approval has been granted by Scania. Modifications may be made by authorised personnel only.
•Modifications affecting the exhaust and intake systems must be approved by Scania.
Environment and safety
Otherwise, the instructions in the Operator's
Manual for the running and inspection of the engine shall apply. The safety precautions should
be observed.
For Scania to guarantee that the engine corresponds to its certified configuration, and take responsibility for any damage and injuries that
occur, inspection must be carried out as above.

The SCR catalytic converter contains vanadium
pentoxide, a chemical known to the State of California to cause cancer.
The SCR catalytic converter is fitted in the silencer and does not constitute a health hazard
during normal use and handling.
When carrying out work on the SCR catalytic
converter which may result in exposure to dust,
safety precautions must be taken. Such work includes, for example, opening the silencer machining and scrapping the SCR catalytic
converter.
Safety precautions when working on the SCR
system.
•Inhalation: If dust is inhaled, the person
should be provided with fresh air immediately. Seek medical attention
•Eye contact: Rinse eyes with water immediately. If irritation persists, seek medical attention.
•Skin contact: Wash with water and soap. Remove contaminated clothes.
•Ingestion: If large amounts have been ingested, drink plenty of water and induce vomiting. Seek medical attention
Environmental hazards
•Vanadium pentoxide is toxic to water organisms and can cause detrimental long term effects to water environment.
Environmental protection measures
•The SCR catalytic converter is a manufactured article that contains vanadium pentoxide, a hazardous substance. Before disposing
of, or scrapping, a spent SCR catalytic converter, it should be tested for any hazardous
characteristics (ignitability, corrosivity, reactivity, acute hazardousness, and toxicity), as
those categories are described in 22 CCR §
66261.30. If the spent SCR catalytic converter exhibits hazardous characteristics and is
being disposed of, it will be considered by the
State of California to be a hazardous waste
subject to Title 22, California Code of Regulations. Before disposing of hazardous waste,
review and follow all pertinent federal and
California requirements.
•Vanadium pentoxide is a listed commercial
chemical product - P120 - pursuant to 22
CCR § 66261.33(e). According to the State of
California, commercial chemical products
that are discarded or intended to be discarded
are hazardous wastes and are subject to all
provisions of Title 22, California Code of
Regulations. Before disposing of vanadium
pentoxide, review and follow all pertinent
federal and California requirements.
•If the SCR catalytic converter is opened for
maintenance, any dust spillages from the catalyst should be collected and tested for the
presence of vanadium pentoxide prior to
proper disposal. Dust spillages should also be
tested for any hazardous characteristics (ignitability, corrosivity, reactivity, acute hazardousness, and toxicity), as those categories
are described in 22 CCR § 66261.30, prior to
proper disposal. If the dust contains either vanadium pentoxide or exhibits hazardous characteristics and is being disposed of, it will be
considered by the State of California to be a
hazardous waste subject to Title 22, California Code of Regulations. Before disposing of
hazardous waste, review and follow all pertinent federal and California requirements.
•Do not dispose of the spent SCR catalytic
converter or its constituent parts into any waterways, storm drains or sanitary sewers.
The SCR catalytic converter contains vanadium
pentoxide, a chemical known to the State of California to cause cancer.
Additional considerations when working on the
SCR system
•Carry out work on the SCR catalytic converter in all well ventilated area. Use protective
goggles and gloves if there is any risk of
splashing or spraying of reductant or coolant.
•When engine is running, the exhaust system
parts can reach such high temperatures that
there is a risk of personal injury. Make sure
that the exhaust system temperature has decreased to a suitable level before starting to
work.
•The SCR system is heated by water from the
engine cooling system. The cooling system
runs at overpressure and when the engine is
hot the coolant is hot. Do not open any hoses
without first stopping the coolant flow in the
hose.
•A P3 type respirator/filter mask or a type
FFP3 fine dust musk, protective goggles and
gloves should be used for any work where
there is a risk of exposure to dust from the
SCR catalytic converter.
•Use a disposable overall and dispose of it
properly after machining.
•Eating, drinking or smoking while working is
not permitted.
•Any dust from the SCR catalytic converter
should be removed using a vacuum cleaner
with microfilter to minimize exposure.
•Make sure that the work surface is cleaned after completed work; Vacuum first then swab.
•Make sure you clean your hands after working with SCR catalytic converter to avoid ingestion.
•Work done on the SCR catalytic converter
may generate waste considered by the State
of California to be a hazardous waste subject
to Title 22, California Code of Regulations.
Before disposing of hazardous waste, review
and follow all pertinent federal and California
requirements.

Starting and running
3.
If the engine has a battery master switch:
Switch on the power by means of the battery
master switch.
4.
Start the engine.
If the fuel tank has been run dry or if the engine
has not been used for a long time, bleed the fuel
system.
Never use starter gas or similar agents to help
start the engine. An explosion may occur in the
intake manifold with a risk of personal injury.
Only start the engine in a well ventilated area.
When the engine is run in an enclosed space,
there must be effective devices to extract exhaust
gases and crankcase gases.
Running the engine without reductant in the reductant tank violates emissions legislation and
will damage the SCR system.
Checks before running
Carry out a daily inspection as described in the
inspection schedule prior to operation. See the
Inspection section.
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
Starting the engine
For environmental reasons the Scania engine has
been developed to be started with a low fuel feed.
Using unnecessarily large amounts of fuel when
starting the engine always results in emissions of
unburnt fuel.
Property of American Airlines
The starter motor must only be cranked twice for
30 seconds at a time. After that, it must rest for at
least 5 minutes before the next attempt to start it.
Starting at low temperatures and at
high altitudes
Take the local environmental requirements into
account. Use a fuel heater and engine heater to
avoid starting problems and white smoke.
Scania recommends that an engine heater should
be used if the engine will be used at temperatures
below -10°C or at an altitude of more than 2,000
metres.
A low engine speed and a moderate load on a
cold engine limits white smoke, gives better
combustion and warms up the engine more
quickly than warming it up with no load.
Avoid running it longer than necessary at idling
speed.
Check instruments and warning lamps at regular
intervals.
Engine speed range
600-750 rpm Low idling. Engine idling is controlled by the engine management system.
Low idling up to 2,100 rpm Engine operating speed range. Controlled by the engine management sys-
tem.
2,100-2,600 rpmUnsuitable operating speed, but a slightly higher engine speed than the nor-
mal maximum operating speed may occur when load is low or negative.
2,600-3,000 rpmProhibited engine speed.
Emission control
The system provides a warning if there are faults
on the SCR system or if the level of reductant in
the reductant tank is too low. In the case of some
faults, for example if doser cooling is not working, the torque is reduced.

If a new fault occurs within 40 hours of operation
since the first fault, the warning lamp will come
on. After 30 minutes of operation, the warning
lamp will flash rapidly and torque will be reduced to 0% (low idling) within 30 minutes.

that the SCR system is functioning again. A service technician must then reset the system so that
the torque returns to the normal level.
The torque reduction applies only to engines that
are certified according to Tier 4.
Normal coolant temperature during operation is
80-90°C/176-194°F.
Alarm levels are set in the engine control unit.
The default setting for the lowest and highest
limit values for high coolant temperature are
95°C/203°F and 105°C/221°F respectively.
The following function is standard as alarm for
high coolant temperature:
•Alarm and torque reduction at the lowest limit value.
Depending on the engine configuration, the following alarm functions may also be available:
•Alarm only.
•Alarm and engine shutdown at the highest
limit value.
•Alarm, torque reduction at the lowest limit
value and engine shutdown at the highest limit value.
•Alarm and engine shutdown at the highest
limit value with the possibility of engine shutdown override control.
•Alarm, torque reduction at the lowest limit
value and engine shutdown at the highest limit value, with the possibility of engine shutdown override control.
If run for extended periods under an extremely
light load, the engine may have difficulty in
maintaining the coolant temperature. At an increased load the coolant temperature rises to the
normal value.
Oil pressure
Information about the normal oil pressure and
lowest permitted oil pressure is contained in the
section headed Technical Data.
The engine management system has the following alarm levels:
•At an engine speed below 1,000 rpm and an
oil pressure below 0.7 bar/10.2 psi.
•At an engine speed above 1,000 rpm and an
oil pressure below 2.5 bar/36.3 psi for longer
than 3 seconds.
The following function is standard as alarm for
incorrect oil pressure:
•Alarm and torque reduction by 30%.
Depending on the engine configuration, the following alarm functions may also be available:
•Alarm only.
•Alarm and engine shutdown.
•Alarm and engine shutdown override control.
High oil pressure (above 6 bar/87 psi) is normal
when starting a cold engine.
Charging indicator lamp
If the lamp comes on during operation:
•Check and adjust the alternator drive belts as
described under the corresponding inspection
point. See the Inspection section.
An excessively high coolant temperature can
damage the engine.
If the charging indicator lamp is still on, this
could be due to an alternator fault or a fault in the
electrical system.
Belt transmission
When the belt transmission is new, it may make
a squeaking noise when running. The noise is
normal and disappears after 50-100 hours of operation.
The noise does not affect the service life of the
belt transmission.
Starting and running
Note:
IMPORTANT!
WARNING!
IMPORTANT!
Engine shutdown
1.
Run the engine without a load for a few minutes if it has been run continuously with a
heavy load.
2.
Switch off the engine.
The battery voltage must remain on for a few
seconds after the 15 voltage is switched off so
that the control units can store the values and
switch to standby mode.
10 prohibited engine shutdowns will cause a
torque reduction (70% of fuel quantity). Reset
the engine by switching it off correctly once.
There is risk of post boiling and of damage to the
turbocharger if the engine is switched off without cooling.
The power must not be switched off before the
engine has stopped.
If the engine is equipped with a battery master
switch and an SCR system, the SCR system must
run for a while after the ignition has been
switched off to allow it to cool down. During this
period the power must not be cut using the battery master switch.
Checks after running
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are exhaust manifolds, turbochargers, oil sumps, hot
coolant and oil in pipes and hoses.
1.
Check that the power supply has been cut.
2.
Top up the fuel tank. Make sure that the filler
cap and the area round the filler opening are
clean to avoid contamination of the fuel.
3.
Top up the reductant tank. Make sure that the
filler cap and the area round the filler opening are clean to avoid contamination of the
reductant.
4.
If there is a risk of freezing, the cooling system must contain enough glycol.
5.
If the temperature is below 0°C/32°F: Prepare for the next start by connecting the engine heater (if fitted).
Check the coolant level following the first start.
Top up if necessary.
Scania LDF stands for the Scania Long Drain
Field test standard. Approved Scania LDF oils
have been carefully selected after extensive testing. The approval is only granted to the highest
quality engine oils available on the market.
Recommended oil
Scania Oil LDF
Scania Oil LDF-2

Scania Oil E7
Lubrication system
The engine oil must fulfil the following quality
requirements:
•ACEA E5/API CI-4
•ACEA E7/API CI-4+ for fuel with maximum
15 ppm sulphur content (0.0015%)
•For engines not run on low-sulphur fuel, the
TBN (Total Base Number) should be at least
12 (ASTM 2 896).
•Oils with a low ash content (ACEA E9/API
CJ4) are not recommended.
Check with your oil supplier that the oil meets
these requirements.
If the engine is used in areas of the world where
lubricating oil with ACEA or API classification
is not available, the oil grade must be measured
in actual operation. In this case contact the nearest Scania workshop.
For operation at extremely low outdoor temperatures: Consult your nearest Scania representative
on how to avoid starting difficulties.
To be able to extend the oil change intervals using an oil analysis, Scania LDF-2 and LDF-3 oils
must be used.
Oil companies can offer analysis of the engine
oil.
The following conditions must remain fulfilled
when the oil is changed.
•Viscosity at 100°C (212°F): max. ±20% of
original value of the fresh oil.
•TBN (in accordance with ASTM D4739): >
3.5
•TBN (in accordance with ASTM D4739): >
TAN (in accordance with ASTM D664)
•Soot (DIN 51452): < 3%
Such analysis measures the oil's TBN (Total
Base Number), TAN (Total Acid Number), fuel
dilution, water content, viscosity and the quantity of particles and soot in the oil.
Lubrication system
The result of a series of analyses is used as the
basis for establishing a suitable oil change interval.
If the conditions are changed, a new oil analysis
programme must be carried out to establish new
change intervals.
Checking oil level
Checking the oil level with the engine
switched off
Leave the engine off for at least 1 minute before
checking the oil level.
1.
Remove the oil dipstick (1) and check the oil
level. The correct level is between the minimum and maximum marks on the oil dipstick.
2.
Top up with more oil (2) when the oil level is
at or below the lower mark.
Information on the correct oil type is found under
the heading Oil grade.
Renew the oil filter and clean the centrifugal oil
cleaner when changing oil.
•Hot oil can cause burns and skin irritation.
Wear protective gloves and goggles when
changing hot oil.
•Make sure that there is no pressure in the lubrication system before starting work on it.
•The oil filler cap must always be in place
when starting and running the engine to prevent oil being ejected.
Lubrication system
Use a container to avoid spillage. Used oil must
be disposed of as specified in national and international law.
Change oil more often if the engine is subjected
to particularly demanding operation, such as a
dusty environment, or if deposits in the centrifugal oil cleaner are thicker than 28 mm (1.1 in).
1.
Unscrew the oil plug and drain the oil when
the engine is hot.
In certain engines the oil is pumped out by
means of a bilge pump.
When cleaning the centrifugal oil cleaner there
will be some dirt deposits in the rotor cover. If
this is the case, this indicates that the rotor is
working. If it is not working, the cause must be
established immediately.
If the dirt deposit exceeds 28 mm at the recommended intervals, the rotor cover should be
cleaned more often.
The oil may be hot. Carefully remove the cover
from the centrifugal oil cleaner.
Lubrication system
1.
Clean the cover. Unscrew the nut securing
the outer cover.
2.
Let the oil run out from the rotor.
3.
Lift out the rotor. Wipe off the outside. Undo
the rotor nut and unscrew it about 1.5 turns to
protect the bearing.
Take care not to damage the rotor shaft.
4.
If the rotor nut is difficult to get loose, turn
the rotor upside down and fasten the rotor nut
in a vice. Turn the rotor counterclockwise
1.5 turns by hand or use an M20 nut, see illustration.
The rotor must not be put in a vice. Never strike
the rotor cover. This may cause damage resulting
in imbalance.

thread-locking fluid 561 200 if it is loose.
First clean thoroughly using a suitable solvent. Tighten the rotor shaft using socket
wrench 99 520. Tightening torque 27 Nm.
Operational testing need only be carried out if it
is suspected that the centrifugal oil cleaner is not
working properly. For example, if there is an abnormally small amount of deposit in the centrifugal oil cleaner in relation to the distance driven.
The rotor rotates very fast and should continue to
turn when the engine has stopped.
1.
Run the engine until it is warm.
2.
Stop the engine and listen for noise coming
from the rotor. Use your hand to feel if the
filter housing is vibrating.
3.
If the filter housing is not vibrating, dismantle and check the centrifugal oil cleaner.
Clean the centrifugal oil cleaner when renewing
the oil filter.
Otherwise, the oil filter will be blocked and resistance in the filter will increase. If this happens,
an overflow valve in the filter retainer opens and
lets the oil pass without being filtered.
1.
Unscrew the filter cover with a socket
wrench with hexagon driver e.g. 36 mm
socket 588 475.
Lubrication system
Do not use an adjustable spanner or other open
tool as there is risk of damaging the filter cover.
2.
Lift out the filter housing cover with filter element. The filter housing will drain automatically once the filter has been removed.
3.
Detach the old filter from the cover by holding the cover and carefully tapping the entire
filter element against something hard. Remember that there will be oil splashes.
4.
Fit the new filter and tighten the filter cover
to 25 Nm (18 lbf ft).
Ethylene glycol can be fatal if ingested and can
cause skin irritation and eye damage.
The coolant recommended by Scania is a mixture of water with antifreeze and corrosion inhibitor (ethylene glycol). The coolant has several
characteristics which are important for the operation of the cooling system:
•Corrosion inhibitor
•Antifreeze
•Increases the boiling point
Cooling system
The coolant should always contain 35-55% by
volume of antifreeze and corrosion inhibitor so
that the coolant properties ensure that the coolant
works correctly.
The coolant should be changed when the cooling
system is cleaned: every 6,000 hours or at least
every 5 years. Refer to Changing coolant.
Antifreeze and corrosion inhibitor concentration table
35% by volume of Scania antifreeze provides
sufficient protection against corrosion.
Example:
1.
The total volume of the cooling system is 40
litres in this example.
2.
The measured concentration of ethylene glycol is 35% by volume (freezing point -21
°C). According to the table there are 14 litres
of ethylene glycol in the cooling system.
3.
The required concentration of ethylene glycol is 45% by volume (freezing point -30
°C). According to the table, 18 litres of ethylene glycol are required in the cooling system.
4.
Since there are already 14 litres in the cooling system, 4 litres of ethylene glycol must
be added to the cooling system (18 - 14 = 4
litres).
Cooling system
For calculation Adequate protection against corrosion
Antifreeze and corrosion inhibitor concentration table
35% by volume of Scania antifreeze provides
sufficient protection against corrosion.
Example:
1.
The total volume of the cooling system is
10.6 US gallons in this example.
2.
The measured concentration of ethylene glycol is 35% by volume (freezing point -6°F).
According to the table there are 3.7 US gallons of ethylene glycol in the cooling system.
3.
The required concentration of ethylene glycol is 45% by volume (freezing point -22°F).
According to the table, 4.8 US gallons of ethylene glycol are required in the cooling system.
4.
Since the cooling system already contains
3.7 US gallons, fill another 1.1 US gallons of
ethylene glycol in the cooling system (4.8 -
3.7 = 1.1 US gallons).

The following instructions apply to Scania expansion tanks. For other types of expansion
tanks, follow the manufacturer's instructions.
Never open the coolant filler cap when the engine is hot. Hot coolant and steam may spray out
and cause burns.
If the cap has to be opened do it slowly and carefully to release the pressure before removing the
cap. Wear gloves as the coolant is still very hot.
1.
Open the expansion tank cap and check the
coolant level.
– The right coolant level on a cold engine is
even with the lower edge of the filler neck.
– The right coolant level on a hot engine is
approximately 25 mm (1 in) over the lower edge of the filler neck.
2.
Top up with coolant as necessary.
Cooling system
Do not top up large quantities of coolant through
the expansion tank. Top up in accordance with
the instructions in the section headed Changing
coolant instead.
Never fill a large amount of cold coolant in a hot
engine. There is great risk of cracks forming in
the cylinder block and cylinder heads.
Only pour pre-mixed coolant into the cooling
system.
Use only pure fresh water that is free from particles, sludge and other impurities.
1.
Pour a small amount of coolant into a container and check that the coolant is pure and
clear.
2.
Change the coolant if it is contaminated or
cloudy.
3.
Measure the content of antifreeze and corrosion inhibitor with one of the following instruments:
Cooling system

The following rules apply to ethylene glycolbased coolant:
•The antifreeze and corrosion inhibitor content
must be minimum 35 percent by volume for
corrosion protection to be sufficient.
•An antifreeze and corrosion inhibitor content
greater than 55 percent by volume impairs the
ability to protect against frost.
•If ice forms in the coolant, there are disruptions initially, but there is no immediate risk
of damage. The engine should not be subjected to heavy loads when ice starts to form.
Only the product Scania coolant, or other products that are tested to provide proper antifreeze
and protection against corrosion for Scania, may
be used in Scania engines. Products that do not
satisfy the requirements for use in a Scania engine can result in faults in and damage to the
cooling system. This can lead to the invalidation
of Scania's warranty for faults and damage
caused by the use of inappropriate coolant.
The antifreeze and corrosion inhibitor used in
Scania engines should be of the ethylene glycol
type.

Composition of the fuel
The composition of the fuel is extremely important for the operation and service life of the engine and injection system. The engine output and
exhaust gases are also dependent on the fuel
grade.
The requirements and testing standards for the
most important characteristics are described in
the Workshop Manual which can be ordered
from Scania dealers or directly from Scania.
The table shows some of the key properties.

It is important for sulphur-free or ultra-low sulphur fuel to be used on engines with SCR systems certified in accordance with Stage III B/
Tier 4i and Stage IV/Tier 4f to ensure that the
engine operates correctly. Use of the wrong fuel
grade can cause damage to the engine and the exhaust gas aftertreatment system.
From January 2011 legislation in the USA and
Europe requires all diesel engines not used on the
road to be run on sulphur-free or ultra-low sulphur fuel.
In Europe, the fuel should be sulphur-free according to standard EN 590. This means that the
sulphur content must not exceed 10 ppm.
Diesel
In the USA the fuel must be an ultra-low sulphur
fuel in accordance with standard ASTM D975.
This means that the sulphur content may not exceed 15 ppm.
Responsibility
The machine operator is responsible for using
the correct type of fuel to ensure that local laws
are complied with.
Engines without EGR and SCRUp to 2,000 ppm (0.2%)If the sulphur content is higher than
Engines with SCR onlyUp to 500 ppm (0.05%)A higher sulphur content than 15
Engines with both EGR and SCRUp to 350 ppm (0.035%)A higher sulphur content than 15
Note
2,000 ppm, the oil change intervals
must be halved. A higher sulphur
content than 4,000 ppm is not permitted, since this will result in engine damage.
ppm may only be used where
Stage III A/Tier 3 or less restrictive
emission laws apply.
ppm may only be used where
Stage III A/Tier 3 or less restrictive
emission laws apply. A higher sulphur content than 350 ppm is not
permitted, since this will result in
engine damage.
Fuel with a higher sulphur content
than 15 ppm for engines with SCR
systems
If fuel with a higher sulphur content that that
specified in the standard is used on a short-term
basis, this will not cause permanent damage to a
catalytic converter. The catalytic converter may,
however, require fuel with a low sulphur content
for some time after this to regain its normal efficiency.
If fuel with too high a sulphur content is used for
a prolonged period, there is a risk that the catalytic converter will not operate correctly, which
will result in a reduction in engine torque.
At temperatures lower than those specified for
the fuel, paraffin wax may precipitate from the
fuel and block filters, pipes and hoses. The engine can then lose power or stop.
The fuel is adapted for use in the specific climate
of each country. If a vehicle or an engine is to be
operated in a temperature zone with a temperature lower than normal, first identify the temperature properties of that particular fuel.
The properties of the fuel when cold can be improved by adopting one of the following measures before the temperature drops:
•Install an electric fuel heater if this particular
fuel is not suitable for the expected temperature and no fuel is available with the correct
temperature properties.
•Add 0.5-2% alcohol (isopropanol) to prevent
any water in the fuel from freezing and forming plugs of ice. Drain fuel tanks and drain or
renew fuel filters regularly.
Diesel
Mixing kerosene or other paraffins with the fuel
is prohibited. The injectors may be damaged.
Mixing petrol with the fuel is prohibited. In the
long term petrol can cause wear in the injectors
and engine.
Reductant is a urea solution normally known as
AdBlue, DEF or ARLA 32 depending on the
market. On the SCR, the reductant is added to the
exhaust gases before the catalytic converter. This
reduces nitrogen oxide emissions.
Responsibility and quality requirements
The machine operator is responsible for using
the correct type of reductant to ensure that local
laws are complied with.
Reductant for SCR
In order for the emission control to meet the
emission requirements set by the public authorities, the reductant should be specified in accordance with ISO 22 241.
Reductant in accordance with ISO 22 241 is a
solution consisting of urea and water containing
32.5% by weight of urea. The solution freezes at
approximately -11°C. Then both ice and water
always have the same concentration. Always
store reductant at a temperature between -11°C
and 30°C.
Recommended urea contentUrea content limit value
32.5%30-34%
Reductant is normally colourless if no dye is
added.
Reductant is not harmful to the skin. Nor is it toxic in small quantities, but it tastes very unpleasant.
Reductant for SCR
Reductant is extremely corrosive, especially to
aluminium and copper. Therefore, wash off any
spillages on metal and electrical connections as
soon as possible. Water, preferably warm, works
very well for cleaning purposes.
Reductant can dry out and form white or greyish
brown crystals or deposits. Dense deposits which
are formed as a result of heat may need to be
scraped off or heated to more than 500°C.
Reductant has a low surface tension and rapidly
spreads over large areas, which then become
very slippery. Therefore, wash off any spillages
as soon as possible.
If the engine is not being used for an extended
period its cooling system, fuel system and combustion chamber and outside must be protected
against rust.
An alternative to preparing the engine for longterm storage is to start the engine and warm it up
every 6 months.
Handling the engine
The engine can normally stand idle for up to 6
months without preparation. For longer periods
of downtime, the following measures should be
taken. These measures provide protection for approximately 4 years.
Preparing the engine for storage
Preparations for storage:
1.
Thoroughly clean the engine.
2.
Run the engine for a specific period using
special preservative fuel, oil and coolant.
3.
Otherwise prepare the engine for storage (filter renewal, lubrication, etc.).
If the engine is equipped with an SCR system:
The reductant in the SCR system is perishable. If
it is not used, its quality can deteriorate over
time. The reductant tank and the system should
be drained if there are longer periods of downtime.
Reductant is a highly corrosive fluid which must
not come into contact with materials which are
sensitive to corrosion.
Rinse off reductant spillages with plenty of water.
If reductant seeps into electrical connections or
electrical cables, these must be renewed.
If the engine is to be stored with a full cooling
system, use coolant containing 50 percent glycol
by volume. Glycol without nitrite-based inhibitor should be used. Example: BASF G48 or
BASF D542.
Ethylene glycol can be fatal if ingested. Avoid
contact with the skin.
Preservative fuel
Use diesel mixed with Lubrizol 560H or the
equivalent. Mix 1 cm3 (ml)/0.06 in3 Lubrizol
560H in 10 dm3/2.3 US gallons of fuel.
Preparing the engine for storage
Lubrizol 560H contains aromatic hydrocarbons
which are hazardous to health.
•Use spot extractors where there is a danger of
vapour build-up.
•Wear protective goggles and gloves when
handling the fuel.
•Do not use contaminated clothing.
•If it gets in your eyes: Flush with a gentle jet
of water for at least 15 minutes and contact a
doctor.
•If it gets on your skin: Wash with soap and
water.
•If you inhale it: Fresh air, rest and warmth.
•Store in well-sealed containers in a dry, cool,
place out of the reach of children.
Lubrizol is flammable and has a 2A fire rating.
The flashpoint is 27 °C/81°F. In case of fire: Extinguish with carbon dioxide, powder or foam.
Suitable preservative oils are supplied by most
oil companies. Example: Dinitrol 40 or equivalent.
Preparations for storage
Use a container to avoid spillage when draining
the oil, coolant and reductant. Dispose of used
fluids through an authorised waste disposal contractor.
1.
Drain and flush the cooling system. Top up
with preservative coolant.
2.
Warm up the engine on normal fuel. Stop the
engine and drain the oil.
3.
Renew the fuel filter.
4.
Fill the engine with preservative oil up to the
minimum level on the oil dipstick.
5.
Mix preservative fuel in a can. Detach the
fuel pipe at the feed pump suction line and
connect a hose from the can.
6.
Detach the fuel pipe at the overflow valve
and connect a return hose to the can.
7.
Start the engine and run it at about 1,000 rpm
for 20-25 minutes.
8.
Stop the engine, remove the hoses and connect the normal fuel pipes.
9.
Remove the rocker covers and lubricate the
valve mechanisms with plenty of preservative oil. Refit the rocker covers.
Fill with new engine oil immediately or
when the engine is to be reused.
11.
Drain the coolant if the engine is not to be
stored with coolant in the system. Plug and
tape all coolant connections if the engine is
to be stored without a cooling system.
12.
Air cleaner: Clean or renew the filter element.
13.
Cover air intakes and exhaust pipes.
14.
Alternator and starter motor: Spray with water-repellent anti-corrosive oil, CRC 226,
LPS1 or the equivalent.
15.
Spray the outside of bright engine parts, first
with penetrating preservative oil such as
Dinitrol 25B and then with Dinitrol 112 or
the equivalent.
Clearly mark the engine with the storage preparation date, and state that the engine must not be
started or cranked.
Preparing the engine for storage
If the engine is to stand idle for more than a year:
16.
Drain the reductant from the reductant tank.
Batteries
Remove the batteries and trickle charge them at
the battery charging station. This does not apply
to batteries specified as maintenance-free by the
manufacturer.
The same applies to short-term storage, even if
the engine has not been prepared for storage as
above.
Wear gloves and protective goggles when charging and handling batteries. The batteries contain
a highly corrosive acid.
