3.8 INSPECTION AND ADJUSTMENT, DEB PLAY

1.

Remove the valve covers, see chapter
"Removal and installation".

2.

Tighten the DEB attachment bolts to the
specified torque, see main group "Technical
data".

3.

Using special tool (DAF no. 1310477), crank
the engine in the direction of rotation until
cylinder 1 has reached the top dead centre
(TDC) and the valves of cylinder 6 are in
overlap position.

4.

Use set screw (B) to set the DEB clearance
(A) of cylinders 1, 3 and 5, see main group
"Technical data".

5.

Then tighten set screw (B) to the specified
torque, see main group "Technical data".

6.

Using special tool (DAF no. 1310477), crank
the engine in the direction of rotation until
cylinder 6 has reached the top dead centre
(TDC) and the valves of cylinder 1 are in
overlap position.

7.

Use set screw (B) to set the DEB clearance
(A) of cylinders 2, 4 and 6, see main group
"Technical data". Then tighten set screw (B)
to the specified torque, see main group
"Technical data".

8.

Fit the valve covers, see chapter "Removal
and installation".

3.10 INSPECTION AND ADJUSTMENT, V-BELT TENSION

Inspecting the V-belt tension
1.

Check the V-belt tension of the air
conditioning compressor drive using the
Krikit I, special tool (DAF no. 1240442).
Check the V-belt tension of the FAX model
steering pump drive using the Krikit II,
special tool (DAF no. 1240443).

2.

Set the gauge to zero by depressing the
measuring arm (1).

3.

Place the belt tension gauge on the V-belt,
halfway between the two pulleys.

4.

Slowly depress the V-belt by means of the
belt-tension gauge until a click is heard.
Then remove the belt tension gauge
carefully. Take care not to let the measuring
arm move.

5.

Take the reading as indicated by the position
of the measuring arm in relation to the scale.
Compare this reading with the
recommended pre-tension, see "Technical
data".

Adjust V-belt tension of air conditioning
compressor drive
1.

Slacken the upper attachment bolt (1) of the
compressor.

2.

Slacken the lower attachment bolt (2) of the
compressor.

3.

Loosen the attachment bolt from the
threaded spindle which is attached to the
coolant pump.

4.

Shift the compressor using the lock nuts (3)
until the correct V-belt tension is achieved,
see "Technical data".

3.11 CHECKING THE COOLANT FREEZING POINT

When the coolant is hot, there is an
overpressure in the cooling system.
Carefully remove the filler cap to
release the overpressure.
Do not remove the filler cap when the
engine is running.
Coolant is a toxic fluid. Contact with
the skin should therefore be
avoided.
In the event of contact with the skin:
remove with paper or a cloth, wash
with soap and water. If irritation
persists, consult a doctor.
If swallowed: DO NOT induce
vomiting. Rinse mouth, drink two
glasses of water and consult a
doctor.
In the event of inhalation: get some
fresh air and rest.
In order to avoid damaging the
cylinder block, do not top up a warm
engine with coolant.

1.

Check the anti-freeze content of the coolant.
Fill the cooling system with anti-freeze, if this
has not been done yet. Always use only
coolants that meet DAF specifications.

2.

Consult the manufacturer’s instructions for
the correct anti-freeze mixing ratio.
Preferably, use 40% anti-freeze on an
ethylene glycol base. At this percentage, not
only good frost protection, but also good
corrosion protection is guaranteed.
