TURBOCHARGER (HC3-16) REPAIR (CONT).
CLEANING/INSPECTION/REPAIR:
NOTE
Hard carbon deposits will form on the turbocharger parts which are very difficult to remove with
ordinary solvents. The cleaner must be capable of removing hard deposits without damaging the
metal.
1.
Place all parts in a divided wire basket so that parts are not in contact, to avoid damage to precision machined
surfaces.
Dry cleaning solvent is potentially dangerous. Avoid repeated and prolonged breathing
of vapors and skin contact with the liquid. Do not use near open flame, arcing
equipment, or other ignition source. Always wear eye protection and protective clothing.
2.
Soak parts in dry cleaning solvent for 12 to 24 hours.
CAUTION
Do not use wire brush to clean turbocharger parts. Use of wire brush may damage
machined surfaces.
3.
Remove carbon loosened by dry cleaning solvent with soft bristle brush.
4.
Flush all oil passages in bearing housing from drain end, to remove dirt loosened by cleaning.
Live steam used for cleaning shall not exceed 100 psi (690 kPa). During steam cleaning
operations, adequate ventilation, natural or forced, shall be provided. Do not direct live
steam against skin.
Death or serious Injury could occur if compressed air is directed against the skin. Do not
use compressed air for cleaning or drying unless the pressure is/has been reduced to 30
psi (2.11 kgcm2) or less. When working with compressed air always use chip guards, eye
protection, and other personal protective equipment.
5.
