3.2 Storage
For short-term storage before commissioning, please observe the following:
• Store gear units in the fitting position ((please see chapter 7.2 "Installation orientation")) and secure
them against falling,
• Lightly oil bare metal housing surfaces and shafts
• Store in a dry place,
• Temperature in the range from – 5 °C to + 50 °C without large fluctuations,
• Relative humidity less than 60 %,
• No direct exposure to sunlight or UV light,
• No aggressive, corrosive substances (contaminated air, ozone, gases, solvents, acids, alkalis,
salts, radioactivity etc.) in the immediate vicinity,
• No vibration or oscillation
3.3 Long-term storage
For storage or standstill periods in excess of 9 months, Getriebebau NORD recommends the long-
term storage option. With the use of the measures listed below, storage for up to 2 years is possible.
As the actual influences on the unit greatly depend on the local conditions, these times should only be
regarded as guide values.
Conditions of the gear unit and storage area for long-term storage prior to commissioning:
• Store in the fitting position (please see chapter 7.2 "Installation orientation")and secure them
against falling.
• Transportation damage to the external paint must be repaired. Check that a suitable rust inhibitor is
applied to the flange bearing surfaces. If necessary apply a suitable rust inhibitor to the surfaces.
• Gear units with the long-term storage option are completely filled with lubricant or have VCI
corrosion protection agent mixed with the gear oil (see adhesive label on the gear unit, or are not
filled with oil, but rather with small quantities of VCI concentrate.
• The sealing band in the vent plug must not be removed during storage. The gear unit must remain
sealed tight.
• Store in a dry place.
• In tropical regions the drive unit must be protected against damage by insects.
• Temperature in the range from – 5 °C to + 40 °C without large fluctuations.
• Relative humidity less than 60 %.
• No direct exposure to sunlight or UV light.
• No aggressive, corrosive substances (contaminated air, ozone, gases, solvents, acids, alkalis,
salts, radioactivity etc.) in the immediate vicinity.
• No vibration or oscillation
Measures during storage or standstill periods
• If the relative humidity is < 50 % the gear unit can be stored for up to 3 years.
Measures before commissioning
• Inspect the gear unit before commissioning.
• If the storage or standstill period exceeds 2 years or the temperature during short-term storage has
greatly deviated from the standard range, the lubricant in the gear unit must be replaced before
commissioning.
• If the gear unit is completely filled, the oil level must be reduced before commissioning.
• For gear units without oil filling, the oil level for the version must be filled before commissioning.
The VCI concentrate may remain in the gear unit. Lubricant quantities and types must be filled
according to the details on the type plate.
