TURBOCHARGER SMART
REMOTE ACTUATOR (SRA)
REPLACEMENT
[214 SD]
When replacing the Holset VGT Turbocharger as
a complete unit, calibration of the Smart Remote
Actuator (SRA) is not required. This calibration is
completed and stored in the SRA memory at the
Holset assembly plant.
Calibration is only necessary if the SRA has been
removed from the turbocharger, or when
troubleshooting complaints where the
turbocharger is the suspected component (low
power, regeneration issues, opacity complaints,
etc.).
The SRA should be removed, and the
turbocharger sector gear travel should be
checked, prior to performing SRA calibration.
Preliminary Steps
In the event of a suspected problem with the
Smart Remote Actuator (SRA), it is essential to
diagnose the cause correctly. Diagnostic
directions and instructions are in the V-MAC IV
Diagnostic Service Manual, 8-213, VCADS pro
MACK Support Software Guide, 8-364, and the
Te ch To o l.
Use VCADS pro to operate the turbocharger
actuator to determine whether the actuator or the
complete turbocharger should be replaced. If it is
determined that the actuator should be replaced,
follow the instructions given here.
Refer to manufacturer's service manuals before
servicing the turbocharger.
Make certain to record the manufacturer's part
number when removing the turbocharger or SRA
for use in obtaining the correct replacement parts.
