Cleaning components mechanically

7.4.1 Preparation
CAUTION
Component damage and corrosion
If mechanical cleaning is carried out incorrectly, this can lead to damage and
corrosion on the components.
Pay attention to the specifications in this chapter pertaining to mechan-
u
ical cleaning.
CAUTION
Selection of cleaning tools
Turbocharger components are sensitive and easily sustain mechanical dam-
age. The use of needle descalers (for example) or other striking tools dam-
ages the components. Depending on the specification, nozzle rings or tur-
bine casings may have protective coatings which can also be damaged.
Use only soft tools such as rags, brushes or wire brushes.
u
In case of heavy contamination, the cleaning methods described in this
u
chapter (such as soaking, for example) can be repeated until a satisfact-
ory result is achieved.
The disassembly and assembly of the components is described in chapter Fitting and dis-
mantling.
Contaminated water and cleaning agents must be disposed of in an environmentally
u
compatible, professional way and in compliance with locally applicable regulations.
