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.
|
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.
