- Release nuts (72027) and remove the silencer/air suction branch.

If necessary
- Remove studs (72026).

- Reuse 2 studs (72026) for securing the lifting device (90190).
- Fit lifting device and shackle (90195) on the 2 studs according to the above illustration with the nuts (72027).
- Compressor casing (72000) secured on the lifting equipment, not complete, press off only slightly.
- Fit second shackle (90195) and secure to lifting equipment.
- Now completely press off the compressor casing (72000) evenly with the three press-off nuts     (61037) and withdraw.

- Turn the compressor casing over and place it on a shim.


Ensure that the shim does not slip.
- Only allow the compressor casing to rest on flange (F)!
