B3.9 and B5.9 Series Engines
Turbocharger Wastegate Actuator (010-050)
Section 10 - Air Intake System - Group 10
Fit the new boost capsule actuator assembly to the actuator
mounting bracket, and install the mounting capscrews.
NOTE: The wastegate is set accurately from the factory.
Adjustment is not necessary unless the capsule is re-
Connect clean, regulated air pressure to the boost capsule.
NOTE: Wastegate actuator adjustment is not a shortcut to
diagonosing low boost. Use the appropriate symptom tree
to diagnose the cause of the low boost before calibrating
the wastegate actuator, if turbo boost is suspected.
This actuator travel specification applies to the 4B and 6B
NOTE: If the measured wastegate actuator travel is within
specification, do not make any adjustement.
Wastegate Actuator Travel Measurement
NOTE: Adjustment on wastegate actuators is not possible
for engines that were built after January 1998 because
tamper proof actuator links are used. The first engine serial
number is 4536369. If the actuator needs to be replaced,
the whole capsule has to be changed. You can not adjust
the wastegate actuator.
