CAUTION
Water and contamination in the cartridge group
If water or contamination gets into the cartridge group, the turbochar-
ger function may be impaired and parts in the cartridge group may be
damaged.
u
Make sure that water or contamination does not get into the gap
between the sealing cover 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.
u
Remove all traces of contamination from the turbine.
u
After brushing off the contamination, fill the tank with clean water,
not salt water.
u
Submerge the turbine of the cartridge group in clean water, so that
loose particles of contamination detach completely.
u
Lift the cartridge group.
u
Dry turbine and gap between turbine and sealing cover with a weak
jet of compressed air.
u
Lightly spray turbine and gap between turbine and sealing cover with
penetrating oil.
u
Rotate cartridge group back to horizontal position (described proced-
ure in reverse order, see
Cleaning the cartridge group on the turbine
).
u
Dispose of contaminated water and cleaning agent in accordance
with the specifications in the safety data sheet.
