CAUTION
Water and contamination in the cartridge group
If water or contamination penetrates the cartridge group, this can impair
the function of the turbocharger and damage parts inside the cartridge
group.
u
Make sure that no water or dirt enters the gap between the heat sheet
metal and the turbine.
CAUTION
Non-permissible rotor unbalance after cleaning
Unevenly distributed residual contamination deposits lead to rotor unbal-
ance. This can result in bearing or turbocharger damage.
u
Remove all traces of contamination from the turbine.
u
After brushing off the dirt, fill the container (02) with clean water, not salt water.
u
Immerse the turbine of the cartridge group in clean water so that any loose dirt comes
off.
u
Lift up the cartridge group and align it horizontally.
u
Clamp the heat sheet metal to the bearing casing.
u
Dry the turbine and the gap between the turbine and the heat sheet metal with low-pres-
sure pressurized air.
u
Lightly spray the turbine and the gap between the turbine and the heat sheet metal with
penetrating oil.
u
Dispose of contaminated water and cleaning agents in accordance with the information
