Cleaning; Measuring Axial Clearance Of Cartridge Assembly - Mitsubishi S6S-Y3T61HF Service Manual

2.3 Cleaning

CAUTION
(a) When using a commercial neutral detergent, be
sure to use non-corrosive type.
(b) Be careful not to damage components.
When cleaning the compressor cover and the turbine
housing, observe the followings:
(1) Visually check the parts condition before cleaning to
note any burns or abrasions, which may not be
observable after cleaning.
(2) Soak the disassembled parts in the inflammable solvent
(e.g. Die Cleaner T-30 manufactured by Daido
Chemical Industry Corp.) to remove oil contaminants
and carbon attachments. However, do not soak the O-
ring, thrust bearing, and other bearings.
(3) Blow compressed air over the inside and outside
surfaces.
(4) Remove deposits using a plastic scraper or a bristle
brush. After removing deposits, soak the components in
a nonflammable solvent and apply compressed air
again.
