CAUTION
Water and dirt in the cartridge group
If water or dirt gets into the cartridge group, the turbocharger function
may be impaired and parts in the cartridge group may be damaged.
Make sure that water or dirt does not get into the gap between the
u
partition wall and turbine.
CAUTION
Non-permissible rotor unbalance after cleaning
Unevenly distributed residual contamination deposits lead to rotor un-
balance. This can result in bearing or turbocharger damage.
Remove all traces of contamination from the turbine.
u
After brushing off the contamination, fill the tank (02) with clean wa-
u
ter, not salt water.
Submerge the turbine of the cartridge group in clean water, so that
u
loose particles of dirt detach completely.
Raise the cartridge group and align horizontally.
u
Clamp the partition wall with the bearing casing.
u
Dry the turbine and the gap between the turbine and partition wall
u
with a weak jet of compressed air.
Lightly spray the turbine and the gap between the turbine and parti-
u
tion wall with penetrating oil.
Dispose of dirty water and cleaning agent in accordance with the spe-
u
cifications in the safety data sheet.
