6.4.5 Cartridge group, general
Corrosion
If the cartridge group is not put back into operation immediately after
cleaning, parts may corrode.
CAUTION
Immediately after cleaning, install the cartridge group and put it back into

operation.
There can be severe contamination of the compressor wheels due to badly filtered suction air
and of the turbines because of heavy fuel oil operation or carbonized oil. Cleaning during
operation may not suffice to remove such contamination; instead, it may need to be cleaned
mechanically during standard service intervals (see chapter service work).
Remove turbocharger from engine (see chapter Removing and Installing [➙ 11]).

Remove cartridge group (see chapter Dismantling and fitting [➙ 73]).
