2.
caution |
In order to avoid damage to
the diaphragm, do not apply a vacuum
of 62 kPa or higher.
|
Apply the vacuum pressure (of approximately 57 kPa)
until the VG 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 VG 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.
