Information
The moisture separation performance is better if all of the plugs are removed. The period of use
before saturation is then slightly shorter.
5.2.13 Replacing the shaft sealing ring
Once the shaft sealing ring has reached the end of its service life, the oil film in the region of the
sealing lip increases and a measurable leakage with dripping oil occurs.
The radial shaft seal must
then be replaced. The space between the sealing lip and the protective lip must be filled
approximately 50 % with grease on fitting (recommended grease: PETAMO GHY 133N). Take care
that after fitting, the new radial shaft seal does not run in the old wear track.
Information
Special installation rules must be observed when replacing MSS7 seals in order to achieve a normal
operating life. MSS7 seals are two-part seals which consist of a liner with an axial dust lip and a radial
shaft sealing ring with a radial dust lip (Figure 40: MSS7 seal). Please contact the NORD Service
department in case of any queries.

5.2.14 Re-lubrication of bearings in the gear unit
NOTICE
Damage to the gear unit due to insufficient lubricant
There is a risk of bearing failure in the event of inadequate lubrication.
• It is essential to comply with the recommended intervals.
• Only use greases which are approved by Getriebebau NORD.
• Never mix different greases. If different greases are mixed, the gear unit may be damaged due to
inadequate lubrication caused by incompatibility between the different greases.
• Avoid contamination of the grease with foreign substances and washing out of the grease by
lubricating oil.
