8.7 Removing the compressor casing

Removing the compressor casing

u Mark the casing position for assembly.

Fig.38: Removing the compressor casing

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).

5. Undo 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 Pressing off the casing →78).
