3.7 INSPECTION, CYLINDER HEAD

1.

Check the sealing plugs of the cylinder head 

for leaks. If necessary, pressure-test the 

cylinder head.

2.

Inspect the cylinder head for damage to the 

sealing surface and any cracks. If necessary, 

have the cylinder head levelled. See 

"Technical data".

3.8 INSPECTION, ENGINE COMPRESSION PRESSURE

}

Be careful when working on an 

engine at operating temperature.

Hot lubricating oil may escape from 

the engine when it is run without the 

valve covers. Make sure you are 

adequately protected.

A compression measurement is a quick check of 

the sealing of the valves and the head gasket, 

and of the sealing between the cylinder liner and 

the piston rings.

The results of the measurements can only be 

used to compare the cylinders with each other.

1.

Bring the engine up to operating 

temperature.

2.

Remove the engine management system 

supply fuse or supply relay, so that the pump 

units cannot be activated.

3.

Remove the valve covers. See "Removal 

and installation".

4.

Remove the injectors.

5.

Turn the engine a number of times using the 

starter motor, so that any carbon or dirt 

particles in the cylinder are removed.

6.

Fit the dummy injector (DAF no. 1329306), 

compression gauge (DAF no. 1329301) and 

adapter (DAF no. 0694972).

7.

Carry out the measurement by rotating the 

engine using the starter motor, until the 

gauge reading no longer rises. For the 

pressure differences permitted between 

individual cylinders see "Technical data".

8.

Remove the dummy injector and fit the 

injectors.

9.

Fit the valve covers. See "Removal and 

installation".

10. Fit the fuse or relay.

4. REMOVAL AND INSTALLATION

4.1 REMOVAL AND INSTALLATION, ENGINE

}

Suspend the engine securely from 

the hoist, using approved lifting 

gear. 

Various fluids will be released when 

fluid pipes are removed. 

Collect these fluids. Personal safety 

and the risk of fire should always be 

considered.

Note:

Because of the large number of vehicle 

specifications, it is not feasible to exactly specify 

the engine removal and installation procedures 

for every vehicle.

This description only includes the most important 

points requiring attention.

-

Disconnect the earth lead from the battery 

terminal.

-

Avoid opening fluid systems as much as 

possible. If possible, remove and set aside 

the engine components.

-

When removing the engine, ensure that no 

parts or dirt fall into the engine, radiator or 

other components. Therefore, plug all 

openings that are freed.

-

Wiring harnesses are vulnerable. If 

damaged, they may cause failures. Make 

sure these wiring harnesses are stress-free 

and clear of moving parts.

-

Fit all attachment bolts and tighten them to 

the correct torque.

-

The engine should not be allowed to rest on 

the oil sump. Because the oil sump is made 

of sheet material, it will be severely damaged 

by the engine's weight.

4.2 REMOVAL AND INSTALLATION, ENGINE MOUNTS

}

Suspend the engine securely from 

the hoist, using approved lifting 

gear.

Note:

If the engine is lifted slightly it is not necessary to 

disconnect coolant hoses, air inlet hoses and 

torque rods between the engine and the radiator.

Removing the engine mounts
1.

Disconnect the earth lead from the battery 

terminal.

2.

Suspend the engine securely in the hoist. 

3.

Remove the central engine mount fixing 

bolts at the front and/or rear of the engine.

4.

Remove the engine mounts.

Installing the engine mounts
1.

Fit the engine mounts.

2.

Tighten the engine mount attachment bolts 

to the specified torque. See "Technical data".

3.

Connect the battery earth lead.
