Lubrication system

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

litres (11.9 US gallons)

when starting and running the engine to prevent

oil being ejected.

Note:

Change oil more often if the engine is subjected

to particularly demanding operation, such as a

dusty environment, or if deposits in the centrifu-

gal oil cleaner are thicker than 28 mm (1.1 in).

Renew the oil filter and clean the centrifugal oil

litres (9.5 US gallons)

Environment

Use a suitable container. Used oil must be dis-

posed of as specified in national and internation-

al laws and regulations.

Oil volume: Min. 28 litres (7.4 US gallons) Max 34

litres (9.0 US gallons)

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.

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

Cleaning upwards-moving

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.

49

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.

50

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 Scania workshop if the rotor shaft

needs renewing.

Note:

Take care not to damage the rotor shaft.

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

sure it rotates easily.

52

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 need only be carried out if it

is suspected that the centrifugal oil cleaner is

malfunctioning. For example, if there are unusu-

ally few deposits given 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.

- Drain the lubrication system as follows:

2. Detach the oil filter cover with specified tool.

See illustration.

3. Allow the system to drain for approximately

2 minutes.

4. Renew the oil filter.

5. Refit the oil filter cover. Tightening torque

for cover: 25 Nm.

6. Clean the area around the centrifugal oil

cleaner.

Environment

Use a waste oil trolley when draining the centrif-

ugal oil cleaner.

WARNING!

Wear protective gloves and goggles. When the

bottom cover is detached, a small amount of oil

will always run out.

7. Unscrew the bottom cover of the centrifugal

oil cleaner 2 turns without removing the cov-

er. See illustration. Start from a mark on the

cover to see the number of turns.

8. Drain the centrifugal oil cleaner for approxi-

mately two minutes.

54

9. Remove the bottom cover together with the

rotor.

10. Remove the rotor by pulling it straight up

from the cover. See illustration.

IMPORTANT!

Lubricate the threads on the cover and O-rings

with engine oil before they are refitted.

11. Renew the uppermost black O-ring.

12. Renew the 2 lower green O-rings.

1. Unscrew the filter cover using the socket.

IMPORTANT!

Do not use an adjustable spanner or other open

tool, as there is a risk of damaging the filter cov-

er.

2. Lift out the filter housing cover with filter el-

ement. The filter housing will drain automat-

ically once the filter has been removed.

3. Detach the old filter from the cover by hold-

ing the cover and carefully tapping the entire

filter element against something hard. Re-

member that there will be oil splashes.

4. Fit the new filter and tighten the filter cover

to 25 Nm (18 lb/ft).

Cooling system

Antifreeze and corrosion protection

The antifreeze and corrosion protection used in

Scania engines should be of the antifreeze (eth-

ylene glycol) and corrosion protection type.

Only Scania coolant, or other products tested as

antifreeze and corrosion protection for Scania,

may be used in Scania engines. Products that do

not satisfy the requirements for use in a Scania

engine may cause faults in and damage to the

cooling system. This may lead to the invalidation

of Scania’s warranty for faults and damage

caused by the use of unsuitable coolant.

Scania Ready Mix coolant is a pre-mixed coolant

consisting of water, antifreeze (ethylene glycol)

and corrosion protection. In warm markets

where there is no risk of freezing in the cooling

system, the concentration of antifreeze and cor-

rosion protection can be lower than in Scania

Ready Mix 50/50. Scania Ready Mix 35/65 is

suitable for these markets.

Scania Ready Mix 35/65 contains 35% anti-

freeze (ethylene glycol) and corrosion protection

and 65% water.

Water

Use only pure fresh water that is free of particles,

sludge and other impurities. If there is uncertain-

ty about the quality of the water, Scania recom-

mends use of Scania ready-mixed coolants. See

the section Recommended Scania products.

Recommended Scania products

Scania Ready Mix 50/50

Scania Ready Mix 50/50 is a ready-mixed cool-

ant containing 50% antifreeze (ethylene glycol)

and corrosion protection and 50% water. It

should be used in cold countries where there is a

risk of freezing in the cooling system.
