Slightly loosen the screws (72011) and turn the compressor casing
u
(72000) until the swivel lifting eye can be fastened to the lifting gear.
(77006* only provided with the wall insert with acceleration aid.)
NOTICE
If the compressor casing cannot be removed easily, it can be pressed
off using the press-off tool (90042) against the turbine casing. To do
this, the two cover plates (1, 2) must be removed from the hard insula-
tion on the turbine casing.
CAUTION
Axial force
The press-off tool can generate a high axial force and, if it is not used
properly (too much pressure on one side), it can damage the rotor.
It should thus be used alternately on both sides while avoiding ex-
u
cessive pressure on either side.
Loosen the screws (72011) and remove them together with the fasten-
u
ing strips (72012).
Move the compressor casing (72000) with the wall insert (77000)
u
carefully away, doing so horizontally.
Tap the wall insert (77000) out of the compressor casing using a
u
nylon hammer and remove the O-ring seal (77005).
