11.2 REMOVAL OF DD15 TURBOCHARGER
Cleaning the turbocharger is necessary before removal.
PERSONAL INJURY
To avoid injury from hot surfaces, wear protective gloves,
or allow engine to cool before removing any component.
PERSONAL INJURY
To avoid injury from contact with rotating parts when an
engine is operating with the air inlet piping removed, install
an air inlet screen shield over the turbocharger air inlet. The
shield prevents contact with rotating parts.
Prior to removal, visually check for:
□ Missing or loose nuts and bolts.
□ Loose or damaged intake and exhaust ducting.
□ Damaged oil drain lines.
□ Cracked or deteriorating turbocharger housings.
□ External oil leakage or exhaust leaks.
Replace damaged parts with new parts.
To remove the turbocharger, perform the following:
NOTICE:
Do not attempt to remove carbon or dirt buildup on the
compressor or turbine wheels without removing the turbocharger
from the engine. If chunks of carbon are left on the blades, an
unbalanced condition will exist and subsequent failure of the
bearings will result if the turbocharger is operated. However, it
is not necessary to disassemble the turbocharger to remove dirt
or dust buildup.
1. Remove the turbocharger heat shield.
2. Disconnect and remove the CAC ducting at the compressor housing. Remove the
compressor outlet elbow and inlet elbow.
NOTE:
APT air feed line removal applies only to engines without an APT solenoid.
All information subject to change without notice.
