Note:

Note the markings (2, 5) on the cylinder head 

gasket to be replaced and use the same gasket 

when fitting. The cylinder head gaskets can also 

be recognised from the coolant holes (3, 4).

22. Remove any remnants of gasket from the 

cylinder heads and the cylinder block.

23. Check the sealing surfaces of the cylinder 

block.

24. Check the threaded holes in the cylinder 

block for damage and cracking.

25. Using the special tool (DAF no. 0694795), 

check that the amount the cylinder liner 

protrudes above the cylinder block is within 

tolerance. See "Technical data".

26. Check the cylinder head. See "Inspection 

and adjustment".

Installing the cylinder heads
1.

Clean the threaded holes in the cylinder 

block using a screw tap.

Note:

Threaded holes not properly cleaned may 

lead to too low a pre-tension of the cylinder 

head bolts, causing leakage.

2.

Clean and degrease the sealing surfaces of 

the cylinder heads and the cylinder block.

3.

Insert both guide pins (DAF no. 0694912) 

into the threaded holes of the cylinder block.

4.

Place the new gasket(s) on the cylinder 

block, making sure that the letters TOP (1) 

are visible. The cylinder head gasket must 

not be retightened.

Note:

Always replace the cylinder head bolts. See 

"Technical data".

5.

Place the cylinder head(s) on the cylinder 

block and hand-tighten a few new cylinder 

head bolts.

Note:

To prevent the inlet and exhaust manifolds 

from being installed under tension, they must 

be installed before the cylinder head bolts 

are tightened.

6.

Fit the inlet and exhaust manifolds with new 

gaskets and tighten the attachment bolts to 

the specified torque. See "Technical data".

7.

Fit the remaining bolts (M16 and M12) and 

apply a drop of oil to the bearing surface of 

the bolt heads.

8.

Remove the two guide pins and replace 

them with the two remaining cylinder head 

bolts.

9.

Tighten the cylinder head bolts to the 

specified torque and in the correct sequence. 

See "Technical data".

10. Fit the valve sleeve.

11. Fit the push rods

Note:

Make sure that any solid push rods 

(yellow marking and diameter 12 mm) are 

fitted back on the inlet sideonly. These solid 

push rods may be replaced by hollow ones 

(diameter 14 mm).

12. Fit the valve gear.

13. Fit the injectors.

14. If necessary, fit the DEB.

15. Fit the valve covers.

16. Fit the coolant pipe, fit new gaskets to the 

thermostat housing and install it.

17. Fit the injector pipes in sets.

18. Fit the fuel filter onto the coolant pipe.

19. Fit the fuel leak-off pipe between the fuel 

filter and the inlet manifold.

20. If applicable, fit the coolant filter to the 

coolant pipe.

21. Fit the heat shields of the exhaust manifold 

and tighten the attachment bolts to the 

specified torque. See "Technical data".

22. If applicable, fit the air-conditioning bracket.

23. Adjust the V-belt tension of the air-

conditioning compressor.

24. Connect the compressor pipe from the 

charge pipe to the compressor.

25. Connect the inlet pipe between the 

turbocharger and the air cooler.
