● Machines with an oil-injection interference fit and a center hole ≥ M56 have an adapter
installed between the shaft and the shipping brace.
● Tighten the shaft screw ② on the rotor shipping brace to the following torques.
Thread in the shaft extension Tightening torque
M20 80 Nm
M24 150 Nm
M30 230 Nm
M36 350 Nm
M42 450 Nm
Tightening torques for other rotor shipping brace types
● The thread in the shaft extension indicates the rotor weight. This indirectly specifies the
required preload force when axially fixing the rotor.
Thread in the shaft extension Preload
M20 20 kN
M24 30 kN
M30 40 kN
M36 50 kN
M42 60 kN
Axial preload force for other rotor shipping brace types
4.13.7 Working on the underside of the machine
● Never remain under or in the immediate vicinity of the machine when it is lifted. If the lifting
gear or load handling attachments were to fail, the machine could fall. This can result in
death, serious injury or material damage.
● In order to gain easy and safe access to the underside of the machine, place it in a secure
and raised position.
4.13.8 Storage
You must correctly store the machine if you do not install and use it after it has been delivered.
NOTICE
Bearing seizure damage if incorrectly stored
If storage conditions are inappropriate there is a risk of bearing seizure damage. Resulting
damage can include scoring (brinelling) and corrosion.
● Follow the storage guidelines.
