I - RISKS RELATING TO CONTAMINATION
The high-pressure direct injection system is highly sensitive
to contamination. The risks caused by contamination
are:
damage to or destruction of the high pr

K9K, and 750 or 752 or 766 or 768
IMPORTANT
Use the diagnostic tool before any operation is carried
out on the injection circuit to check:
that the injector rail is not under pressure,
that the fuel temperature is not too high.
It is essential to respect the safety and cleanliness
advice whenev
The thrust bearing is connected to the clutch slave cylinder.
REMOVAL
I - REMOVAL PREPARATION OPERATION
Drain the brake reservoir using a syringe to remove
the clutch thrust bearing and control.
