7.2.5 Cartridge group, general
If the cartridge group is not put back into operation immediately after clean-
ing, parts may corrode.
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 op-
eration may not suffice to remove such contamination; instead, it may need to be cleaned me-
chanically 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 [➙ 59]).
First clean the compressor end and then the turbine end according to the following description.
