4.5 Checking the gear unit
During a test run under full load, the gear unit should be checked for:
 Unusual noises, such as grinding, knocking or rubbing noises
 Unusual vibrations, oscillations and movements
 Production of steam or smoke
After the test run, the gear unit should be checked for:
 Leaks
 Slippage of the shrink disks. For this, the cover should be removed and a check carried out
whether the marking described in Section 3.10 shows a relative movement of the hollow shaft
of the gear unit and the machine shaft. Then the cover should be fitted as described in
Section 3.11.

Note!
Shaft sealing rings are rubbing seals and have sealing lips made from an elastomer
material. These sealing lips are lubricated with a special grease at the factory. This
reduces the wear due to their function and ensures a long service life. An oil film in the
region of the rubbing sealing lip is therefore normal and is not due to leakage.
