WARNING

Always hold the intermediate injector union in place with a wrench when loosening the high pressure pipes.

Do not damage the injector return nozzle.

WARNING

To avoid any corrosion or damage, protect the areas on which fuel is likely to run.

WARNING

To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components exposed to the open air.

WARNING

Do not use the screwdriver as a lever on the injector fuel return unions.

WARNING

Ensure that the clip is not completely removed from its housing, otherwise it may be damaged when the diesel return union is removed.

In the case where a clip has been completely removed from its housing, remove the injector concerned and replace the clip with a new clip (see 13B, Diesel injection, Diesel injector: Removal - Refitting, 13B-83).

Note: If the heat protection washer is stuck at the bottom of the well, use the (Mot. 1817) (see Injector well cleaning tool: Use) (Technical Note 6040A, 13B, Diesel injection).

Note: If the injector is stuck in its well and cannot be removed, turn the injector by the retaining lugs on the injector bracket, using a 13 mm fork wrench.

II - REFITTING OPERATION FOR PART CONCERNED

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.

III - FINAL OPERATION

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

Check the condition of the seals on the fuel return unions on the injectors. Check that they are not cut or crushed, and have not come out of their grooves. Replace the diesel return pipe assembly if one of its components is damaged.
