Adjusting the timing gear
1.

Remove the valve cover from cylinders 1-2-

3. See "Removal and Installation".

2.

Position cylinder 1 at top dead centre (TDC

on the flywheel, cylinder 6 in overlap

position).

3.

Remove the timing gear cover. See

"Removal and installation".

Note:

When the crankshaft (1) or the camshaft (2)

of an engine is rotated separately without an

idler gear (3), the engine's pistons may touch

the valves.

4.

Remove the idler gear (3). See "Removal

and installation".

5.

Rotate the camshaft gear (2) to such a

position that the idler gear (3) can be

installed in accordance with the marks.

6.

Fit the idler gear and tighten the attachment

bolt to the specified torque. See "Technical

data".

7.

Fit the timing cover. See "Removal and

Remove the poly-V-belt and switch off the

automatic tensioner (0). See "Removal and

installation".

2.

Place a torque wrench on the hexagonal

head of the automatic tensioner.

3.

At the specified torsional distance (A) the

torsional moment must have a certain value.

See "Technical data".

The automatic tensioner must be replaced if

the measured value is not the same as the

reference value.

4.

Fit the poly-V-belt. See "Removal and

installation".

3.5 INSPECTION AND ADJUSTMENT, V-BELT TENSION

Inspecting the V-belt tension
1.

Check the V-belt tension of the airc

onditioning-compressor drive with the Krikit I,

special tool (DAF no. 1240442).

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 main group

"Technical data".

Adjusting the V-belt tension of air
conditioning compressor drive
1.

Slacken the central bolt (1) of the tensioning

roller.

2.

Turn the adjusting screw (2) until the V-belt

tension is correct. See "Technical data".

3.

Tighten the central bolt (1).

3.6 INSPECTION, FLYWHEEL

1.

If the flywheel shows cracks on the abutting

surface with the clutch plate, the flywheel

may be ground down, provided that the

cracks are not within 5 mm of the inner rim.

2.

The flywheel has an indicator groove for

inspection purposes.

3.

Grinding down is allowed until the indicator

groove is no longer visible. This means that

a maximum of 2 mm may be ground down.

Checking flywheel run-out
1.

Clean the flywheel.

2.

Place a metal strip on the edge of the

flywheel housing to fit a dial gauge.

3.

Place the dial gauge on the metal strip.

4.

Place the stylus of the dial gauge at the

specified distance. See "Technical data".

5.

Set the dial gauge to "0".

6.

Use the special tool (DAF no. 1310477) to

crank the engine through 360

°, and measure

the maximum dial gauge reading. Compare

this reading with the technical data. See

"Technical data".
