3. Move control rack by means of special tool
No.VR00148/0 into idle injection position
(approx.5-6 mm) (ill.3) and remain in this
position.
4. Put tool (unit injector withdrawing lever No.
VR00126/0) onto rocker arm of individual
unit injectors (ill. 4) and move upper end of
lever in direction of air intake manifold. As
a result, unit injector is pressed down and
injection process is simulated.
5. Adjust control rack by means of special
tool No.VR00148/0 to partial load (approx.
10-12 mm in direction full delivery) (ill.3)
and remain in this position.
Failure diagnostic via manual cracking point at
low quantity setting:
Proceedings:
Rack had been lock and linking lever were
readjusted to ensure proper quantity setting
as specified.
NOTE:
When moving the unit injectors, forces
from the injector spring can be felt. As soon
as fuel delivery starts a slight extra force can
be noticed on the lever for very short moment
until the needle in the injector cracks open
and this slight pressure increase disperses
again. This creaking point can be used as
reference when remaining the common rack
at the same position this forces must be felt
on each of the installed injectors. That way
injectors who do not show a creaking point
have a failure. Further investigations, for
example air in the fuel system or mechanical
