10.Carefully lift out the complete rotor using suitable lifting and stopping equipment.
11.Lay the rotor down in a safe location. Suitable for this are timber beams of appropriate size.
12.Loosen the mounting screws on the bearings cover.
13.Pull the bearing housing off using a

Mounting the Main Bearings
1.Before mounting, clean the bearing surfaces and the shaft surfaces thoroughly and grease lightly.
2.Mount bearing in bearing housing.
3.Attach the bearing with the bearing housing to the rotor axis.
4.Lift the rotor using suitable lifting and stopping equipment and place carefully into the bearing seats
5.Attach the bearing housing to the bearing seats using screws.
6.Push the distance sleeve onto the rotor axis.
7.Put the gear onto the rotor axis
8.Put back the rotor cover plates
9.Put in the screen
10.Pull on
11.Attach the
12.Carry out a test run.
NOTE:
•The roller bodies will be damaged unless the mounting forces engage into inner ring.
•The hardened bearing rings are sensitive to impact stress; never hit the rings with the hammer. Use a brass arbor or a striking bushing (piping piece) made from a soft material. The inner diameter of the striking bushing should be only slightly larger than the diameter of the bearing base.
•The bearing is then pushed onto the shaft using light blows. The force of pressure must be evenly distributed on the circumference of the bearing ring.
Lubricating the Main Bearings
An important requirement for high operational safety and long service life of the arrangement of bearings is the correct lubricant supply. Every machine is greased and checked in test runs before delivery.
NOTE: Unsuitable lubricant, lubricant deficiency, excessive lubricant, or impurities in the lubricant lead to overheating and extreme wear of the bearings.
