Cleaning components mechanically
6.2.1
Preparation
CAUTION
Component damage and corrosion
If mechanical cleaning is carried out incorrectly, this can lead to damage and
corrosion on the components.
u
Pay attention to the specifications in this chapter pertaining to mechan-
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.
u
Use only soft tools such as rags, brushes or wire brushes.
u
In case of heavy contamination, the cleaning methods described in this
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
u
Contaminated water and cleaning agents must be disposed of in an environmentally
compatible, professional way and in compliance with locally applicable regulations.
