Maintenance
Cleaning components mechanically
Clean compressor wheel with a scouring cloth or soft brush soaked in
water with household cleaning agent. Do not use any wire brushes!
Dry the compressor wheel and the gap between the compressor and
the bearing casing with a weak jet of compressed air.
Lightly spray the compressor wheel and the gap between the com-
pressor and the bearing casing with penetrating oil.
Dispose of contaminated water and cleaning agent in accordance with
the safety data sheet.
Cleaning the cartridge group on the turbine end
Soaking the contamination
Baked layers of contamination from fuel residue or coked oil may occur at
the turbine end. The contamination can be removed by soaking and
brushing. The procedure for soaking the layers of contamination as well
as for cleaning the turbine are described in the following.
To soften the layers of contamination on the turbine, the cartridge group
can be submerged vertically in a tank with liquid.
The cartridge group must be rotated to do this.
Two cranes (or chain blocks) must be used for the rotating operation.
Suspending the chain block directly from the crane and rotating the car-
tridge group is not permitted because of the risk of damage to the com-
pressor wheel.
