8.7.2 Mounting the main bearing
To mount the bearings proceed as follows:

Before mounting, clean the bearing surfaces and the shaft surfac-
es thoroughly and grease lightly.

Mount bearing in bearing housing.

Attach the bearing with the bearing housing to the rotor axis.
HINT
•
During mounting, the mounting forces must always en-
gage into the inner ring, otherwise the roller bodies will
be damaged.
•
The hardened bearing rings are sensitive to impact
stress. For this reason, never hit directly on the rings
with the hammer, use instead preferably a brass arbor or
better still 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. When doing this, the force of pressure must be
evenly distributed on the circumference of the bearing
ring.

Lift the rotor using suitable lifting and stopping equipment and
place carefully into the bearing seats

Attach the bearing housing to the bearing seats using screws.

Push the distance sleeve onto the rotor axis.

Put the gearbox motor onto the rotor axis

Put back the rotor cover plates

Carry out a test run.
