5.4 BLEEDING THE FUEL SYSTEM

While bleeding the fuel system, fuel 

will escape. Collect the fuel to avoid 

the risk of fire.

Dirt in the fuel system can lead to 

significant damage to pump units 

and housing.

Note:

The fuel system has to be bled if it has been 

opened; this can be done in two ways.

-

With the fuel lift pump

-

By pressurising the fuel tank

Bleeding using the fuel lift pump
1.

Loosen the union nut on the injector.

2.

Pump fuel out of the injector pipe with the 

primer pump until no more air bubbles are 

visible in the fuel.

3.

Tighten the union nut to the specified torque, 

see "Technical data".

4.

Repeat points 1, 2 and 3 for the other 

injectors.

Bleeding by pressurising the fuel tank

To prevent deformation of the fuel 

tank, the delivery pressure in the fuel 

tank must not exceed 0.4 bar.

1.

Remove the fuel tank cap and replace it by a 

cap with an adjustable air connection.

Note:

Use a cap (without a vent) that has a 

connection for a pressure reducer valve.

2.

Pressurise the tank to a maximum of 0.2 bar.

3.

Loosen the union nut on the injector.

4.

Tighten the union nut to the specified torque, 

see "Technical data".

5.

Repeat points 1, 2 and 3 for the other 

injectors.

5.5 DRAINING AND FILLING, DIFFERENTIAL

To prevent skin injury, avoid 

unnecessary contact with the 

drained oil. 

Version: 1339 and 1347 axles

Draining the differential
1.

Position the vehicle on a level surface.

2.

Remove the level check/filler plug (A) and 

drain plug (B). Drain the oil.

3.

Fit the plug using the special Torx wrench 

(DAF no. 1329493) and tighten to the 

specified torque; see "Technical data".

Filling the differential
1.

Fill the differential gear through the level 

check/filler plug (A) with the specified 

quantity of oil; see "Technical data".

2.

Check the oil level after approx. 5 minutes: it 

should reach up to the level check/filler plug.

3.

Fit the level check/filler plug (A) using the 

special Torx wrench (DAF no. 1329493) and 

tighten to the specified torque; see 

"Technical data".

Version: 1354 axle

Draining the differential
1.

Position the vehicle on a level surface.

2.

3.

Fit the plug using the special Torx wrench 

(DAF no. 1329493) and tighten to the 

specified torque; see "Technical data".

Filling the differential
1.

Fill the differential gear through the level 

check/filler plug (A) with the specified 

quantity of oil; see "Technical data".

2.

Check the oil level after approx. 5 minutes: it 

should reach up to the level check/filler plug.

3.

Fit the level check/filler plug (A) using the 

special Torx wrench (DAF no. 1329493) and
