8.

Remove the attachment bolts from the timing 
gear case and remove it.

Installing the timing gear case
1.

Apply a sealant to the sealing surface of the 
cylinder block. See "Technical data". Apply 
the sealant in accordance with the pattern 
and at the indicated location. The bead has 
to be 1.5 to 2.0 mm thick. Fit the timing gear 
case with liquid gasket and tighten the 
attachment bolts to the specified torque. See 
"Technical data".

Note:
If too much sealant is used, or if the sealant 
is applied in a wrong place, this may cause 
obstruction of an oil duct or oil sump 
ventilating duct. This could result in serious 
damage.

2.

Fit the oil sump attachment bolts and tighten 
them to the specified torque. See "Technical 
data".

3.

Fit the camshaft gear.

4.

Fit the high-pressure pump.

5.

Fit the air compressor.

6.

Fit the steering pump.

7.

4.23 REMOVAL AND INSTALLATION, FRONT CRANKSHAFT SEAL

Removing the front crankshaft seal
1.

Remove the attachment bolts from the fan 
and place it in the wind tunnel.

2.

Remove the poly-V-belt.

3.

Remove the attachment bolts from the 
vibration damper and remove it, along with 
the crankshaft pulley.

4.

Fit the threaded spindle (2) of the special tool  
(DAF no. 1329474) on the crankshaft flange.

5.

Screw the push/pull piece (1) onto the 
spindle up to the engine top panel.

Note:
Mark the drill at a length of 18 mm using a 
piece of tape.

6.

Drill a hole through the base plate to the tape 
marking and fit a screw in the seal to keep 
the base plate in its place.

7.

Drill the other five holes and fit screws.

8.

Turn the threaded spindle (2) clockwise until 
the seal has been removed.

Installing the front crankshaft seal
1.

Clean and inspect the seal chamber. Even 
minimal damage may cause a leak.

2.

Fit the threaded spindle (2) of the special tool  
(DAF no. 1329474) on the crankshaft flange.

3.

Put a new seal over the crankshaft.

4.

Screw the push/pull piece (1) onto the 
threaded spindle (2) up to the seal.

5.

Turn the threaded spindle (2) anti-clockwise 
until the push/pull piece (1) is level with the 
panel. The seal has been properly fitted once 
it is level with the engine top panel.

6.

Remove the special tool.

7.

Inspect the vibration damper.

8.

Fit the crankshaft pulley and the vibration 
damper and tighten the attachment bolts to 
the specified torque. See "Technical data".

9.

Fit the poly-V-belt.

10. Fit the fan.

5. CLEANING

5.1 CLEANING THE ENGINE

Note:
It is advisable to clean the engine with a high-
pressure cleaner before starting maintenance or 
service operations. A clean environment makes 
your work easier, and enables you to notice any 
engine defects at an early stage.

Before cleaning the engine, check for any leaks.

If the engine is cleaned with a high-pressure 
cleaner, the high-pressure cleaner must be used 
with care. It is also important to observe the 
following points:

-

When cleaning the universal joint on the 
steering box, the spider seals may be forced 
open by the high-pressure jet of water, so 
that the grease behind them is flushed away. 
As a result, the spider may get stuck, so that 
the steering mechanism will jam.

-

There is an air bleed vent on the power 
steering fluid reservoir of the steering gear. 
Water may enter the reservoir through this 
air bleed vent, causing damage to the 
steering gear.

-

When cleaning the radiator/air cooler 
element, be careful not to damage the fins.

-

Do not direct the high-pressure cleaner jet 
too long at the air-conditioning system 
condenser. As a result of the high 
temperature, the pressure in the system will 
become excessive, which may cause 
damage to the system.

-

Ensure that no water can enter the gearbox 
via the air bleed vents.

-

Make sure that no water can enter via the 
clutch reservoir bleed vents.

-

The engine compartment can be cleaned 
with a high-pressure cleaner. Never direct 
the jet of water towards electrical 
components.

-

When cleaning UPEC engines with a high-
pressure cleaner, do not aim the jet directly 
at the pump units. Water could penetrate into 
the protective covers via the bleed holes. 
This could result in failures in the electrical 
connections of the pump units.

-

Do not direct the jet of water at electrical 
connections such as connectors or lead-
throughs of the vehicle lighting system.

-

Ensure that no water can enter the air intake 
system via the air intake or its flexible seals.
