CAUTION
Do not remove carbon or dirt buildup
from the compressor or turbine
impellers. The turbocharger must be
disassembled to thoroughly clean
the impellers. Even small deposits
remaining on the blades unbalance
the
impeller
and
damage
the
turbocharger.
Check for carbon or dirt buildup on impellers
(4) and casing port. If buildup is present, the
turbocharger must be cleaned. Notify direct
support.
Check for oil on the impeller (4). The
presence of oil indicates seal leaks. Oil seal
leaks are caused by blocked air intake ducts
or damaged oil seals. If the air filter and in-
take ducts are not blocked, the turbocharger
oil seals must be replaced. Notify direct
support.
