Main shaft and bearing

Repair manual

KM/285/EN/1.1.0

When replacing the bearings, check the following issues:

• straightness of the shaft

• location of the mechanical seal on the shaft (the surface must be free of

scratches)

• external condition of the bearing housings

• external condition of the drive flange (particularly where the shaft seal rubs

against the drive flange).

Measuring the straightness of the shaft

The straightness of the shaft is measured from three points (figure 13).

Figure 13. Measuring the straightness of the shaft

Supporting point 1

Supporting point 2

Measuring point

The maximum permissible deviation measured from the surface of the shaft is

0.15 mm, in which case the dislocation of the centre line is 0.075 mm.

NOTE!

Measure the straightness carefully.

Excessive deviation in the straightness will cause several

problems, the most significant being the excessive wearing of

the impeller and bearings.

2.1.3. Assembly of the front bearing

The front bearing must be assembled before it can be reinstalled. Clean all

parts of old lubricants and dirt before assembly.

Assembly of the front bearing:

1. Install the mechanical seal.
