Labels for filled engine oil grade

When changing oil it is important to use the cor-

rect engine oil grade. The oil filler cap must be

clearly marked with a label showing the filled oil

grade. However, there are only labels for oils

with Scania LDF approval and oil grade

ACEA E7.

Stick on a new label if the oil type or oil grade is

changed in favour of any of the oil types above.

Replace the label if it is missing.

Checking the oil level

REQUIREMENT!

Leave the engine off for at least 7 minutes before

you check the oil level.

If the oil level exceeds the maximum level, the

oil must be changed. Check the cause if the oil

level exceeds the maximum level and contact

your nearest workshop with qualified personnel

if you suspect a fault.

1. Remove the oil dipstick (1) and check the oil

level. The correct level is between the mini-

2. Fill with more oil at point 2 in the illustration

when the oil level is at or below the lower

Changing the oil

WARNING!

Hot oil can cause burns and skin irritation. Wear

protective gloves and eye protection when

changing hot oil. Make sure that there is no pres-

sure in the lubrication system before changing

the oil. The oil filler cap must always be in place

Max. 45 litres (11.9 US gallons).

Note:

Change oil more often if the engine is subjected

to particularly demanding operation, such as a

dusty environment, or if deposits on the paper in

the centrifugal oil cleaner are thicker than 28 mm

(1.1 in).

Renew the oil filter and clean the centrifugal oil

Environment

Use a suitable container. Used oil must be dis-

posed of as specified in national and internation-

al laws and regulations.

1. Unscrew the oil plug and drain the oil when

the engine is hot. In certain engine types the

oil is pumped out by means of a bilge pump.

Min. 28 litres (7.4 US gallons).

If the engine is drained via the valve, the oil

should be hot. Alternatively, use a pump.

This so that draining occurs more quickly.

2. Wipe off the magnet on the oil plug.

3. Renew the gasket on the oil plug.

4. Refit the oil plug.

5. Fill with the amount of oil specified for the

oil sump.

6. Wait at least seven minutes.

7. Check the level on the oil dipstick.

Cleaning the centrifugal oil

cleaner

WARNING!

The oil may be hot. Carefully remove the cover

from the centrifugal oil cleaner.

Use eye protection and protective gloves when

working on the centrifugal oil cleaner.

When the centrifugal oil cleaner is cleaned, there

should be some dirt deposits on the paper in the

rotor cover. If the paper is clean, the equipment

is not working as it should. If this is the case, in-

vestigate the cause of this.

Renew the paper more frequently if the dirt de-

posits are thicker than 28 mm (1.1 inches) during

a scheduled oil change.

1. Clean the cover.

2. Unscrew the nut securing the outer cover.

3. Let the oil run out from the rotor.

x 1.5

4. Lift out the rotor. Wipe off the outside.

5. Loosen the rotor nut and unscrew it about

1.5 turns.

Note:

Take care not to damage the rotor shaft.

36

Lubrication system

6. If the rotor nut is jammed: Turn the rotor up-

side down and fasten the rotor nut in a vice.

See illustration.

7. Use protective jaws so as not to damage the

M20

grooves of the rotor nut.

8. Turn the rotor 1.5 turns anti-clockwise by

hand.

9. If this does not work: Screw two nuts togeth-

er with an M20 screw.

10. Position the screw head at the bottom of the

x 1.5

rotor.

11. Position a ring spanner on the lower nut and

turn the rotor 1.5 turns anti-clockwise.

IMPORTANT!

Do not attach the rotor directly to the vice. Never

strike the rotor cover.

12. Remove the rotor cover by holding the rotor

in both hands and tapping the rotor nut

against the table. Never strike the rotor di-

rectly as this may damage its bearings.

13. Remove the strainer from the rotor cover. If

the strainer is stuck, insert a screwdriver be-

tween the rotor cover and strainer and care-

fully prise them apart.

37

Lubrication system

14. Remove the paper insert.

15. Scrape off any remaining dirt deposits from

the inside of the rotor cover. If the deposits

on the paper are thicker than 28 mm (1.1 in),

the centrifugal oil cleaner must be cleaned

more often.

16. Wash the parts according to the applicable

industrial method.

17. Inspect the 2 nozzles on the rotor. Ensure that

they are not blocked or damaged.

Renew any damaged nozzles.

18. Check that the bearings are undamaged.

Renew damaged bearings.

19. Fold and fit a new paper insert on the inside

of the rotor cover as illustrated.

20. Fit the strainer onto the rotor.

21. Fit a new O-ring to the foot of the centrifugal

oil cleaner.

22. Refit the rotor cover. Ensure that the O-ring

is not outside the edges, but is in the groove.

23. Screw the rotor nut back on by hand.

24. Check that the shaft is not damaged or loose.

Contact a workshop with qualified personnel

if the rotor shaft needs to be renewed.

Note:

Take care not to damage the rotor shaft.

25. Refit the rotor and rotate it by hand to make

sure it rotates easily.

39

26. Fit a new O-ring in the cover.

27. Refit the cover and tighten the lock nut.

Tightening torque 20 Nm (15 lb-ft).

IMPORTANT!

To reduce the risk of oil leakage it is important to

tighten the cover to the correct tightening torque.

Operational testing of the

centrifugal oil cleaner

Operational testing only needs to be performed if

you suspect that the centrifugal oil cleaner is not

functioning as it ought to. This may, for exam-

ple, be due to abnormally small deposit on the

paper in the centrifugal oil cleaner in relation to

the distance driven.

1. Run the engine until it reaches normal oper-

ating temperature.

2. Switch off the engine and listen for the sound

from the rotor. It should continue rotating for

a time, even when the engine has stopped.

3. Use your hand to feel if the filter housing is

vibrating.

4. If the filter housing is not vibrating, disman-

tle and check the centrifugal oil cleaner.

40

Lubrication system

Renewing the oil filter

IMPORTANT!

Clean the centrifugal oil cleaner at the same time

as you change the oil filter. Otherwise, the oil fil-

ter will become clogged and the oil will pass the

filter without being cleaned.

1. Remove the old filter.

2. Oil the rubber gasket on the new filter.

3. Fit the new filter and tighten it by hand. Nev-

er use tools because the filter could sustain

damage, obstructing circulation.

4. Start the engine and check for leaks.

Renewing an air filter with a

non-renewable element

IMPORTANT!

If the engine has an air filter with a non-renewa-

ble Scania element, it should be renewed instead

of cleaned.

Cooling system

Risk of freezing

IMPORTANT!

The engine should not be subjected to heavy

loads if ice starts to form in the cooling system.

If the coolant starts to freeze, the water in the

coolant starts to crystallise and the ethylene gly-

col content in the coolant increases. If freezing

produces a great increase in the amount of ice,

circulation problems could arise. There is no risk

of damage by freezing if the content of Scania

antifreeze and corrosion inhibitor, or an equiva-

lent mixture of a similar product, is at least 35%

by volume.

Minimal ice formation in the coolant sometimes

causes minor problems without any risk of dam-

age. For example, the auxiliary heater may not

work for up to one hour after the engine has been

started.

The following example shows coolant properties

with 30 percent by volume of antifreeze and cor-

rosion inhibitor:

• Ice slush starts to form at -16°C (3°F).

• At -30°C (-22°F), there is a risk of cooling

system malfunction.

• There is no risk of damage by freezing with a

minimum antifreeze and corrosion inhibitor

content of 35 percent by volume.

Example: If the temperature is -16°C (3°F), there

is a risk of damage by freezing if the percentage

of antifreeze and corrosion inhibitor is 20% by

volume. At 30% antifreeze and corrosion protec-

tion by volume the coolant will not contain any

ice.
