3.4 CHECKING THE FLUID LEVEL OF THE CAB TILTING PUMP

1.

The fluid level must be checked when the 
cab is in the driving position.

2.

The cock (2) should be in the "tilting back" 
position (anti-clockwise).

3.

Unscrew the filler plug (1) 3 to 4 turns. Wait 
until the overpressure, if any, has left the 
reservoir. Remove filler plug (1).

4.

Start pumping (maximum 5 pump strokes). 
Ensure that the pump lever is in the lowest 
position.

5.

Check the fluid level. This level should be no 
more than 2 cm below the top of the filling 
opening. Top up if necessary.

6.

Fit the filler plug (1) and hand tighten it.

3.5 CHECKING THE CAB FASTENING

1.

Check that all attachment bolts are in place.

2.

Visually inspect the attachment of the cab to 
the tilting mechanism.

3.

Visually inspect the seals and condition of 
the tilting mechanism.

3.6 INSPECTION, ENGINE OIL LEVEL

1.

Ensure that the vehicle is standing on a flat 
and level surface.

2.

Wait at least 5 minutes before checking the 
engine oil level of a hot engine.

3.

Pull the dipstick (2) out of the holder.

4.

Wipe the dipstick clean with a lint-free cloth.

5.

Put the dipstick back into the holder.

6.

Pull the dipstick out again and check the oil 
level. 

7.

If necessary, top up oil via the filler opening 
with the red cap (D) to the maximum oil level.
Always use the specified oil.
Do not top up above maximum level.

Note:
For the difference between minimum and 
maximum engine oil level, see "Technical 
data".

3.7 INSPECTION AND ADJUSTMENT, VALVE CLEARANCE

1.

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

2.

Use the special tool (DAF no. 1310477) to 
turn the crankshaft clockwise, as seen from 
the timing gear end (this corresponds with 
the engine's direction of rotation), until the 
valves of cylinder 1 are in the overlap 
position. The pistons of cylinders 1 and 6 are 
now at top dead centre.

Note:
"Overlap" is the moment at which the inlet 
valve starts opening and the exhaust valve 
finishes closing.

If the engine has a DEB, you must 
use a flat ring spanner to loosen the 
lock nut. This is necessary to avoid 
damaging the DEB spring plate.

3.

Check/correct the valve clearance of cylinder 
6. Set the correct valve clearance by 
loosening the lock nut and turning the 
adjusting screw in the correct direction. See 
"Technical data" for the correct valve 
clearance.

4.

By cranking the crankshaft 1/3 stroke each 
time, using special tool (DAF no. 1310477, ) 
the valves can be adjusted according to the 
injection sequence 1-5-3-6-2-4.

5.

If the engine has been fitted with a DEB, the 
DEB play must be checked following the 
valve play adjustment.

6.

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