Fig. 13: Removing the high-pressure stage
1. Loosen screws (72013) between bellows (82300) and compressor casing (72000) and re-
move with washer (72014). The air suction branch (82000) with the bellows does not have
to be dismantled from the air line. To protect the bellows, the high-pressure stage must
not be lifted up together with the radial air suction branch and the bellows.
2. If present: Unplug the plug to the speed sensor (86505) and secure the rolled-up
cable (2 m) to the high-pressure stage. This protects the plug from being crushed.
3. Treat the threads of the threaded rods (42191) and fixing screws (02) of the sup-
port (61300) with penetrating oil and allow it to take effect. Do not oil the pressure
screws of the clamping nut (42201).
4. Attach lifting gear to high-pressure stage with two swivel lifting eyes (03).
5. Loosen and remove the fixing screws (02) of the support (61300).
u
Loosen the clamping nuts (42201) in accordance with the following section.
