Alternative 2
- Set the No. 1 cylinder to TDC by turning the engine in its direction of
rotation until both valves are closed.
- Adjust both the valves for the No. 1 cylinder. Correct valve clearance is
indicated on the instruction plate on one of the rocker covers.
- Repeat this procedure with the remaining cylinders in the order 5 - 4 - 2
- 6 - 3 - 7 - 8 (firing order) by turning the engine 1/4 revolution in its
direction of rotation between each adjustment.

CHANGING (or CLEANING) VALVES
FOR CLOSED CRANKCASE
VENTILATION
Alternative 1:
Change the valves at the specified interval.
Alternative 2:
- Remove the valves at the specified interval.
- Clean the valves by placing them in a bath of diesel oil overnight.
Then rinse them several times in diesel oil and leave them to drain off.
- Refit the valves.
- The valves may be reused (cleaned) no more than twice after the
first 1,200 hours of use. Be sure to mark the valves in connection
with cleaning them.

LONG-TERM STORAGE
If the engine is not to be used for a lengthy period of time, special measures
should be taken to protect the cooling system, fuel system and combustion
chamber from corrosion and the exterior from rusting.
The engine can normally stand idle for up to six months. If it remains unused
for longer than this the following measures, which provide protection for
about four years, should be adopted. An alternative to preparing the engine
for long-term storage is to start the engine and warm it up every 6 months.
Preparing the engine for long-term storage means:
- Thoroughly cleaning the engine
- To run the engine for a period of time with preservative fuel,
preservative oil and preservative coolant.
- Otherwise preparing the engine for storage (filter changes, lubrication,
etc.).
-
Preservative coolant
If the engine is to be stored with a full cooling system, use coolant containing
Ethylene glycol, if swallowed
50% glycol by volume. Glycol without nitrite-based inhibitor must be used.
can be fatal.
E.g. BASF G48 or BASF D542.
Avoid contact with the skin.
Preservative fuel
- Use diesel fuel mixed with Lubrizol 560A or equal.
- Mix 1 cm3 (ml) of Lubrizol 560A with 10 dm3 (l) of fuel.
!
HANDLING LUBRIZOL 560A
Hazardous!
Contains aromatic hydrocarbons
Use spot extractors where there is a danger of vapour build-up.
Wear protective gloves and goggles when handling Lubrizol. Do not use contaminated clothing.
In case of splashes in the eye: Rinse with moderate water spray (for min. 15 minutes). Seek medical attention.
In case of skin contact:
Wash affected areas with soap and water.
If you inhale it:
Fresh air, rest and warmth
Flammable:
Fire class 2A. Flash point + 27°.
In case of fire: Extinguish using carbonic acid, powder or foam
Storage:
In properly sealed container in a dry, cool place. Keep out of reach of children.

Preservative oil
Suitable preservative oil can be supplied by most oil companies.
E.g. Dinitrol 40 or the equivalent.
Preparations for storage
-
Drain and flush the cooling system. Fill with preservative coolant.
-
Run the engine until warm with ordinary fuel. Stop the engine and drain
the oil.
Always use suitable containers
-
Change fuel filter and turbo filter.
to avoid spillage when
draining oil and coolant.
-
Fill the engine with preservative oil to the minimum level on the
dipstick.
Dispose of used oil and coolant
through an authorized waste
-
Mix the preservative fuel in a can. Detach the fuel pipe at the feed pump
disposal contractor.
suction line and connect a hose from the can.
-
Detach the fuel pipe at the overflow valve and connect a return hose to
the can.
-
Start the engine and run it at about 1000 rpm for 20 - 25 minutes.
-
Stop the engine, remove the hoses and connect the normal fuel lines.
-
Oil the valve mechanism with plenty of preservative oil.
-
Remove the injectors and spray preservative oil into each cylinder
max. 30 cm3(ml).
Crank the engine several revolutions using the starter motor. Spray a
small amount into each cylinder.
The engine must not then be cranked. Refit the injectors.
-
Drain the preservative oil from the engine. New engine oil can be filled
directly or when taken out of preservative.
-
Drain the coolant if the engine is not to be stored with a full cooling sys-
tem. Plug and tape over all coolant connections (if the cooling system is
not completely assembled).
-
Air cleaner: Clean and change the filter insert.
-
Cover air intakes and exhaust pipes.
-
Alternator and starter motor:
- Spray with water-repellent anti-corrosive oil, CRC 226, LPS1 or the
equivalent.
-
Spray the outside of shiny engine parts, first using penetrating preserva-
tive oil such as Dinitrol 25B and then using Dinitrol 112 or the
equivalent.

2001-05:1
- Attach a clear notice to the engine with the date of preservation and
stating that the engine must not be started or cranked.
STORED ENGINE
Date
Must not be started or cranked.
Batteries
Remove the batteries for maintenance charging in the charging station. (Does
not apply to batteries which, according to the manufacturer, are maintenance-
free). The same also applies to short periods of disuse, even if the engine is
not stored as above.
Taking out of storage
(action when the engine is taken into service)
- Remove plugs and tape from coolant connections, air intakes and
exhaust pipes.
- Fill the cooling system with coolant, see page 18.
- Check the oil level in the engine and top up with new oil.
- Crank the engine several revolutions with the injectors removed, oiling
the valve mechanism, pushrods and tappets with plenty of oil.
Important: The engine must be cranked with the injectors removed so
that excess preservative oil can be forced out of the cylinders.
- Fit the injectors.
- Drain the fuel system’s main filter of preservative fuel.
- Bleed the fuel system.
- Wash off externally applied preservative oil using white spirit.
Winter storage
The fuel tank or tanks should be filled up during winter storage to reduce the
risk of condensate forming.

FUEL
Diesel fuel
The composition of the diesel fuel is vitally important to the operation and
life of the engine and the fuel injection pump. The engine power output and
the exhaust emissions are also dependent on the fuel quality.
The requirements and the test standards for the most important properties are
Additives must not be used.
described in the workshop instruction in sections that can be ordered from your
Scania dealer or directly from Scania. The address of Scania is printed on the
cover.
The diesel fuel shall comply with the following standard:
EN 590 (European standard).
The table below shows the requirements for some of the most important
properties:
Property
Requirement
Viscosity at 40°C
2.0 - 4.5 mm2/s (cSt)
Density at 15°C
0.82 - 0.86 kg/dm3
Sulphur (concentration by mass)
max. 0.3%
Ignitability (CET rating)
min. 49
Flashpoint
56°C
Environmentally favourable fuels (low sulphur fuels)
There are three different grades of so called environmentally favorable fuels
(SS15 54 35). Grade 1 is sulphur-free and grade 2 is low in sulphur.
Compared with class 3 (normal fuel), these fuels are less dense and this
reduces engine power output. Only class 1 fuel should be used with a
catalytic converter.
Short term use of fuel with a higher sulphur content than 0.05% by weight
will not cause permanent damage to the catalytic converter.
The catalytic converter may, however, require fuel with low sulphur content
for some time after this to regain its normal efficiency.
