Remove contamination manually with a soft brush or wire brush.
CAUTION
Water and contamination in the cartridge group
If water or contamination gets into the cartridge group, the turbocharger
function may be impaired and parts in the cartridge group may be dam-
aged.
Make sure that water or contamination does not get into the gap be-
tween the partition wall and turbine.
CAUTION
Non-permissible rotor unbalance after cleaning
Invisible and unevenly distributed residual contamination deposits lead
to rotor unbalance. This can result in bearing or turbocharger damage.
Remove all traces of contamination from the turbine.
After brushing off the contamination, fill the tank with clean water, not
salt water.
Submerge the turbine of the cartridge group in clean water, so that
loose particles of contamination detach completely.
Lift the cartridge group.
Dry turbine and gap between turbine and sealing cover with a weak jet
of compressed air.
Lightly spray turbine and gap between turbine and sealing cover with
penetrating oil.
Rotate cartridge group back to horizontal position (described proce-
dure in reverse order, see Cleaning the cartridge group on the turbine
Dispose of contaminated water and cleaning agent in accordance with
