• The fuel system must be checked for leaks after service work referring to "Fuel Leakage Check Procedure: ".
• The fuel system is very sensitive to contamination. The risks caused by the introduction of contamination are:
– damage or destruction of the high pressure injection system and the engine.
– seizing or leaking of a component.
• When servicing on the high pressure direct injection system, must be performed under very clean conditions.
This means that no impurities (particles a few microns in side) get into the system during dismantling or into the
circuits via the fuel unions.
• The cleanliness principle must be applied from the fuel filter to the injectors.
• Contamination is caused by:
– metal or plastic chips,
– paint,
– fibres: boxes, brushes, paper, clothing, cloths,
– foreign bodies such as hair,
– ambient air,
– etc.
• It is not possible to clean the engine using a high pressure washer because of the risk of damaging connections.
In addition, moisture may collect in the connectors and create electrical connection problems.
• The technician should wear clean overalls.
• Ensure that you have the plug caps (1) for the unions to be opened. Plug caps are to be used once only. After use,
they must be thrown away (once used they are soiled and cleaning is not sufficient to make them reusable).
Unused plug caps must be thrown away, also.
NOTE
• Plug cap set is available as a spare part.
• Plug unions as soon as possible when removing / disconnecting fuel system component in order to
prevent dust from invading.
Similarly, do not remove plug cap immediately before when installing / connecting fuel system
component.
