3) Cleaning
With the turbocharger completely dismantled for overhaul, soak all the components in a non-
caustic metal cleaner to loosen deposits. Bead blast the turbine housing if chemicals do not
clean sufficiently.
On aluminium parts a bristle brush can be used. Never use a wire brush or metal scraper on
any turbocharger component. Ensure that all the palls are finally cleaned with an air jet,
especially drilled passages and machined apertures. Turbine Wheel: In the event of carbon
build-up, it may be necessary so carefully blast the Piston Ring
Groove area of the turbine wheel using low grade shot medium.
