4.2 REMOVAL AND INSTALLATION, INJECTOR

}

Due to the presence of overpressure 

in the fuel tank, fuel may run into the 

cylinders when removing injectors. 

Therefore, when removing injectors, 

always first remove the tank cap. 

Collect any fuel from the injectors.

Removing the injector
1.

Disconnect the earth lead from the battery 

terminal.

2.

Remove the injector pipes as a set.

3.

Remove the valve cover.

4.

Remove the DEB.

5.

Remove the attachment bolt (3) from the 

injector clamp. To remove the injector and 

the clamping piece, only use the special 

tools (DAF no. 1329412) and 

(DAF no. 0694928).

Note:

If during removal one or more copper shims 

(1) remain in the injector sleeve, the injector 

will be reinstalled in a higher position.

As a result, instead of spraying into the 

combustion chamber of the piston, the fuel 

will be sprayed onto the piston ring. This may 

seriously damage the piston.

There will be inadequate sealing between 

the O-ring (2) of the injector and the cylinder 

head. Fuel leaking from the injector can flow 

freely into the engine and dilute the 

lubricating oil.

grease to both rings.

3.

Inspect the valve sleeve seal (3) of the 

injector. Replace it if it is leaking and/or 

damaged.

Note:

Make sure that the injector clamp is installed 

correctly.

4.

Fit the injector together with the injector 

clamp (4) and tighten the attachment bolt to 

the specified torque. See "Technical data".

5.

Fit the DEB.

6.

Adjust the DEB clearance.

4.3 REMOVAL AND INSTALLATION, INJECTOR SLEEVE

Removing the injector sleeve
1.

Partially drain the coolant.

2.

Remove the injector.

Insert a ball of crumpled paper into the 

injector sleeve to prevent metal particles 

from entering the engine.

3.

Tap a thread (M22 x 1.5) over a length (A) of 

approx. 20 mm in the injector sleeve that is to 

be removed.

Turn the special tool (DAF no. 1310425) into 

the injector sleeve and, using the special tool 

(DAF no. 0694928), remove the injector 

sleeve.

Installing the injector sleeve
1.

Clean the injector sleeve opening 

thoroughly.

Note:

Fit the dry injector sleeve in the cylinder 

head.

Use the special tool (DAF no. 1329305) to 

tap the injector sleeve into the cylinder head.

2.

4.4 REMOVAL AND INSTALLATION, PUMP UNIT

}

When removing the pump unit, fuel 

will escape. Collect this fuel, bearing 

in mind the risk of fire.

}

Dirt in the fuel system can lead to 

significant damage to pump units 

and housing.

Removing the pump unit
1.

Disconnect the earth lead from the battery 

terminal.

2.

Remove the electrical connections from the 

pump unit.

3.

Remove the fuel pipes from the pump 

housing.

4.

Remove the pressure relief valve from the 

pump housing.

5.

Let the fuel leak from the pump housing.

6.

Remove the injector pipes in sets and plug 

the pump units and injectors so that no dirt 

can enter.

7.

If it is necessary to replace the pump unit(s), 

the pump unit must be marked so that it can 

be replaced in the same position in the pump 

housing.

Note:

The pump unit may be under spring tension, 

depending on the position of the camshaft in 

the pump housing.

8.

Remove the attachment bolts from the pump 

unit.
