1.Remove the vacuum hose
from the variable geometry actuator. Connect the hand vacuum
pump
to the nipple.

2.
caution |
In order to avoid damage to
the diaphragm, do not apply a vacuum of -60
kPa or higher.
|
By applying the vacuum pressure until the variable
geometry actuator link touches the
stopper bolt, fully shrink the actuator rod. The vacuum
pressure is approximately -55 kPa at
that time. 3.Leak the vacuum pressure gradually as
much as possible to check the vacuum pressure
when the variable geometry actuator rod moves approximately
1.5 mm in the extension direction. Standard
value: -46.1 - -49.2 kPa 4.If the
vacuum pressure significantly deviates from the standard
value, check the actuator
or the variable nozzle. Replace the turbocharger assembly if
necessary.

Apply the vacuum pressure (of approximately -57 kPa)
until the variable geometry actuator
link touches the stopper bolt. This allows the actuator rod
to fully shrink. 3.Leak the vacuum pressure
gradually as much as possible to check the vacuum pressure
when the variable geometry actuator rod moves approximately
1 mm in the extension direction. Standard
value: -52.0 - -55.0 kPa 4.If the
vacuum pressure significantly deviates from the standard
value, check the actuator
or the variable nozzle. Replace the turbocharger assembly if
necessary.
