Removing the compressor casing internal part

Remove two studs (74029 / 74026) at the point where the lifting
device (90190) will be fitted later.

Using press-off screws (90900), push apart the compressor casing in-
ternal part (76000) until the lifting device (90190/90195) can be at-
tached.

Slightly lift and then withdraw the compressor casing internal part in-
cluding the wall insert and diffuser.

Attach the support angle (90025) using screws (90021) and nuts
(74027).

Put down the compressor casing internal part including the wall in-
sert and diffuser on the support angle and an underlay.

Remove the O-ring (76040).
