5.2.1 Visual inspection
The gear unit must be checked for leaks. Attention should be paid to escaping gear oil and traces of
oil on the exterior or underneath the gear unit. In particular, the radial seals, cover caps, screw plugs,
hoses and housing joints should be checked.
If leaks are suspected, the gear unit should be cleaned, the oil level checked (5.2.6 "Oil level") and
checked again for leaks after approx. 24 hours. If a leak is confirmed (dripped oil), the gear unit must
be repaired immediately. Please contact the NORD Service department.
Information
Shaft sealing rings
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.

5.2.2 Running noises
