n
Close openings on components and engine immediately with
suitable plugs/caps.
n
Plugs/caps must only be removed just before the installation.
n
Keep plugs/caps in their original packaging, where they are
protected against dust and dirt, dispose of after one time use.
n
Take new parts out of their original packaging just before instal-
lation.
n
Removed components must be stored in new, sealable bags or
– if available – in the packaging material of the new compo-
nents.
n
Always use the original packaging material of the new part to
return the disassembled old component.
n
For work, such as the removal and assembly of defective com-
ponents on the Common Rail System, it is highly recom-
mended to cordon off a dedicated area in the workshop. This
area must be spatially separated from other areas (which are
used for general vehicle repairs, like brake repairs)
n
The workshop floor must be sealed or tiled.
n
No welding equipment, grinding machines, general machine
tools, brake or power test benches must be operated in this
room.
n
Periodic cleaning of this workshop area is obligatory, draughts,
ventilation system and heating blowers must be minimized.
n
A special work place must be set up for work on disassembled
components.
n
Clean disassembly and assembly tools at regular intervals and
keep these in a closed tool cabinet.
n
Remove loose parts (e.g. paint scales that may have come off
during assembly work) with an industrial vacuum cleaner or
any means of extraction.
n
Working means and tools must be cleaned before being used
for work. Use only tools without damaged chromium coating, or
tools without chromium coating.
1.3.1.1.4 Repair notes for gaskets and mating surfaces
Leaking sealing faces can mostly be traced back to incorrect
assembly of seals and gaskets.
n
Before assembling a new seal or gasket make sure that the
sealing surface is free of pitting, flutes, corrosion or other
damage.
n
Inappropriately stored or handled seals (e.g. hanging from
hooks or nails) must under no circumstances be used.
n
Install seals and gaskets only with sealing compound, grease
or oil, if this is specifically specified in the repair instructions.
n
If necessary remove any old sealing compound before assem-
bling. For this purpose do not use any tools that could damage
the sealing surfaces.
