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 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.

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.
