1. Loosen screws (72011) and remove together with fastening strips (72012).

2. Attach swivel lifting eye (S) to the compressor casing and the lifting gear.

3. Remove the compressor casing (72000) and turn it 180°.

4. Remove and dispose of the O-ring (42012) or graphite cord sealing (42126).

5. Loosen screws (79041) and remove from the compressor casing (72000) with fixing

discs (79040) and diffuser (79000).

If the compressor casing cannot be loosened, it can be pressed off against the turbine cas-
ing using the press-off tool (90042) (see chapter
