| IMPORTANT
Consult the safety and cleanliness advice and operation
recommendations before carrying out any
repair. |
IMPORTANT
Use the diagnostic tool before any operation is carried
out on the injection circuit to check:
- that the rail is not under pressure,
- that the fuel temperature is not too high.
Working on the circuit with the engine running is
strictly forbidden. |
IMPORTANT
During this operation, be sure to:
- refrain from smoking or bringing red hot objects
close to the working area,
- be careful of fuel splashes when disconnecting the
union.
|
| WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run. |
REMOVAL
I - REMOVAL PREPARATION OPERATION
- Remove the front engine cover.
- Disconnect the battery.
- Rotate the intercooler air inlet pipe clip (1) on the turbocharger.
- Remove the intercooler air inlet pipe bolt (2) from the
fuel pipe support.
- Move the intercooler air inlet pipe to one side.
- Remove:
- the protector plate (3) from the injector rail protector
- the injector rail protector
- the oil separator
- the diesel injector fuel return rail
II - OPERATION FOR REMOVAL OF PART
CONCERNED
| Note:
Loosen the pipe nuts one by one. |
| Note:
Do not allow any diesel fuel to enter the engine
via the rocker cover opening during this operation. |
- Undo:
- the high pressure pipe nuts on the injectors using a
17 mm long lever spanner, part number 77 11
223 720,
- the high pressure pipe nuts on the injector rail using
- 19 mm long lever spanner, part number 77
11 223 721.
- Remove the high pressure pipes between the rail
and the injectors one by one.
- Insert the blanking plugs.
REFITTING
I - REFITTING PREPARATION OPERATION
- Always replace:
- the high pressure pipes between the injector rail
and the injectors,
- the intercooler air inlet pipe seal.
| WARNING
Before fitting a new high pressure pipe, lightly
lubricate the nut threads with the oil from the
applicator provided in the new parts kit.
Be careful not to allow oil into the high pressure
pipe.
Do not lubricate high pressure pipes supplied
without an applicator, as these high pressure
pipes are self-lubricating. |
| WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehicle. |
II - REFITTING OPERATION FOR PART
CONCERNED
- Remove the blanking plugs.
| Note:
Tighten the high pressure pipes between the rail
and the injectors one by one. |
- Fit:
- the high pressure pipe olives between the rail and
the injectors in the injector rail tapers,
- the high pressure pipe olives between the rail and
the injectors in the injector tapers.
- Manually tighten the high pressure pipe nuts between
the rail and the injectors, starting with the nuts
on the injector rail side.
- Torque tighten:
- the high pressure pipe nuts on the injectors (32
N.m) using a 17 mm long lever spanner, part
number 77 11 223 720,
- the high pressure pipe nuts on the injector rail
(32 N.m) using a 19 mm long lever spanner, part
number 77 11 223 721.
III - FINAL OPERATION
- Refit:
- the diesel injector fuel return rail
- the oil separator
- the injector rail protector.
- Remove the intercooler air inlet pipe seal using a
tweezers.
| Note:
Check that the seal (4) on the intercooler air inlet
pipe is fitted the correct way round. |
- Refit:
- the new seal of the intercooler air inlet pipe,
- the protector plate on the injector rail protector.
- Turn the intercooler air inlet pipe to refit the clip in its
housing.
- Clip the intercooler air inlet pipe onto the turbocharger.
- Refit the intercooler air inlet pipe bolt on the fuel pipe
support.
- Torque tighten the intercooler air inlet pipe bolt (8
N.m).
- Connect the battery.
- Prime the fuel circuit using the manual priming pump.
- Refit the engine cover.
