Table40: Tightening torque (61037 / 61090)
1. Distributed evenly around the circumference, screw the press-off nuts (61090) onto the
studs of the bearing casing and turn them by hand until they are at the end of the thread.
2. Grease the new O-ring (42012) and fit it.
3. Fasten lifting device (90190 / 90195) to compressor casing (72000) and secure to crane.
4. Position the compressor casing(72000).
Tighten nuts (61037) crosswise.
5. Remove lifting device (90190 / 90195).
6. Tighten the three press-off nuts (61090) against compressor casing (72000) by applying
the corresponding tightening torque.
