Using circlip pliers, remove and discard
the two circlips (64) and the journal
bearing (11) from the compressor end.
Turn the bearing housing over and repair
the process.
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.
