9.3.5 Measurement.
The hub with radial walls must be aligned both vertically and horizontally with the casing. If
measurement indicates that there are discrepancies, the radial walls, and possibly also the hub, will need
to be adjusted.

Start measuring at the upper radial wall.

Measure the distances
A
and
B
between the radial walls and the casing at points
1
,
2
,
3
and
4
.

Measure similar points on the next radial wall.

Check that values
A
and
B
are the same for both radial walls at all points and that these values
match approved tolerances.
2
If the tolerance is not achieved, undo the screw at the wing of the hub and adjust the radial wall
horizontally.
