Risk of damage to property and production disruption
Thread of the bell disk can be damaged.
First, screw the bell disk onto the shaft by hand, without a torque
wrench. Just apply manual force.
Screw the bell disk onto the shaft only if it can be done easily.
If the bell disk is screwed improperly onto the shaft end of the turbine,
the threads of bell disk and turbine may be damaged. An improperly
mounted bell disk leads to irreparable damage to the turbine.
• Set the bell disk on the shaft end manually and turn the bell disk a
few times on the thread.
• For final tightening, set the torque wrench on the special tool.

• Remove the torque wrench from the bell disk using the special tool.
