<Actuator shaft length adjustment>
•
Remove snap rings and pins on the actuator side of the shaft.
• Loosen the lock nut. Turning the joint part, extend the shaft until
the control crank contacts the position bolt.
Adjusting guide: Shaft length changes by 1 mm with one turn of
the joint.
• After the adjustment, reinstall the snap rings and pins, and tight-
en the lock nut.
NOTE
• If proper control crank-to-position bolt contact cannot be
achieved despite full shaft extension, replace the lever and
pins.
• Measure boost pressure again.
• If boost pressure is out of the standard value, check the turbo-
charger. (See later section.)
(3.2) If boost pressure is too high
<Position bolt length adjustment>
•
Loosen the lock nut.
• Using a hexagon wrench, turn the position bolt in illustrated di-
rections to bring it into a position clear of the control crank.
(Turn the starter switch ON. If the engine warning lamp stays off
for more than 30 seconds, it is in normal condition.)
Adjusting guide: With the engine running at 2500 rpm, one full
turn of the position bolt increases boost pressure by approxi-
mately 3 kPa.
• After the adjustment, tighten the lock nut.
• Measure boost pressure again.
• If boost pressure is out of the standard value, check the turbo-
charger. (See later section.)
CAUTION
• If shaft stroke is out of specified standard value (18.5 to 21
mm), the engine electronic control unit detects it as a turbo-
charger adjustment error (common rail system diagnosis
code P2263: VGT System) and indicates it through engine
warning lamp. In such a case, check the turbocharger for
responsible fault.
Delete the diagnosis code appearing on the Multi-Use Tes-
ter screen because it is otherwise memorized in the engine
electronic control unit. (See Gr00.)
