4.
If the operation of the valve of the wastegate is not
correct, the actuator rod (4) requires adjustment.
Remove the dial indicator from the end of the actuator
rod.
5.
Keep the air pressure applied to the actuator (6).
Release the locknut on the actuator rod (4). Remove
the clip (2). Remove the actuator rod from the pin (3).
The pin is on the arm of the valve of the wastegate.
6.
If the air pressure was too low, rotate the actuator rod
(4) in the direction which reduces the length of the
actuator rod. If the air pressure was too high, rotate the
actuator rod in the direction which increases the length
of the actuator rod. Rotate the length of the rod in
increments of one-half turn.
NOTE:
Use only the end of the threaded rod in order to
make adjustments. Pushing or pulling the
actuator rod could change the calibration of the
actuator. Changing the calibration could increase
the wastegate boost which could damage the
engine.
7.
Place the pin (3) through the actuator rod (4) and
through the arm of the wastegate valve. Install the clip
(2). Tighten the locknut (5). Release the air pressure.
8.
Repeat Step 2 through Step 7 until the operation of the
wastegate is correct.
Lubrication System
SMCS Code: 1300
Fluid Spillage Containment
Care must be taken in order to ensure that fluids am contained
during performance of inspection, maintenance, testing,
adjusting and repair. Collect all fluids with suitable containers
before opening any compartment or disassembling any
component that contains fluids. For tools and supplies that are
suitable for collecting fluids and containing fluids, refer to the
Tools And Shop Products Guide, NENG2500. Also refer to
your local regulations and requirements.
Inspect The Oil Pump
If any pa of the oil pump is worn enough in order to affect the
performance of the oil pump, the oil pump must be replaced.
Perform the following procedures in order to inspect the oil
pump. Refer to Specifications, "Engine Oil Pump" for
clearances and torques.

Cover of the oil pump.
(1) Bolts for the cover
1.
Remove the oil pump from the engine. Remove the
cover of the oil pump.
2.
Remove the outer rotor. Clean all of the parts. Look for
cracks in the metal or other damage.
