STORAGE & COMMISSIONING
RETAIN FOR FUTURE USE
1. Storage
IMPORTANT NOTE
For storage periods longer than 9 months, or for storage
in less than desirable conditions, please consult NORD for
recommendations.
Storage for up to 9 months is possible, so long as the follow-
ing conditions are observed:
• Store the gear unit in its actual mounting position in
accordance with the specifi ed oil fi ll-level, in a clean and
dry temperature controlled area. Avoid temperature
fl uctuations within the range of 0°C and 40°C (32°F to
104°F) and avoid relative humidity conditions in excess
of
60%.
• Protect all exposed or unpainted shaft and fl ange surfaces
with an anti-corrosion agent or grease.
• Store in a location free from shock and vibration, to avoid
false brinelling of bearing elements and raceways.
• Whenever possible, rotate the shafts periodically, by hand
if necessary, to help prevent brinelling (bearing damage)
and to help keep the shaft seals pliable.
• Avoid direct exposure to the sun or UV light and aggressive
or corrosive materials in the environment (ozone, gases,
solvents, acids, caustic solutions, salts, radioactivity, etc.
2. Commissioning
Prior to gear unit start-up, complete the following:
• Check the lubricant and be sure the gear unit is fi lled with
the proper oil type, to the proper level, as determined by
the mounting position.
IMPORTANT NOTE
Some smaller gear units are supplied as maintenance free/
lubricated for life gear units. Oil level may not be checked
on some of these units.
• Check the condition of all shaft seals and all assembled
fl ange gasket areas. If any change is detected in the
shape, color, hardness or permeability, or if any leaks are
detected, the corresponding shaft seals and/or gaskets
must be replaced.
• Remove all anti-corrosive metal protectant from
otherwise bare metal surfaces. Follow product manufac-
turers directions and warnings during surface protection
removal.
• Check the resistance of all motor and brake windings to
verify the integrity of the winding insulation and inspect
all terminal box openings and wire connection areas to
verify that all components are dry and free of corrosion.
3. Long-Term Storage
By taking special precautions, problems such as seal leakage
and reducer failure due to the lack of lubrication, improper
lubrication quantity, or contamination can be avoided. The
following precautions will protect gear reducers during peri-
ods of extended storage:
• Store the gear unit in its actual mounting position in
accordance with the specifi ed oil fi ll-level, in a clean and
dry temperature controlled area. Avoid temperature
fl uctuations within the range of 0°C and 40°C (32°F to
104°F) and avoid relative humidity conditions in excess
of
60%.
• Fill the reducer full with oil that is compatible with the
product normally used or recommended during service.
• Apply grease to all unpainted or unprotected shafts,
bores, keyways, fl ange surfaces, tapped holes, and to the
exterior of all oil seals.
• Store in a location free from shock and vibration, to avoid
false brinelling of bearing elements and raceways.
• Once every few months rotate the input shaft
approximately 10-20 revolutions to redistribute the
weight of gears and shafts and to prevent brinnelling of
the bearings and drying of the seal track.
• Avoid direct exposure to the sun or UV light and aggressive
or corrosive materials in the environment (ozone, gases,
solvents, acids, caustic solutions, salts, radioactivity, etc.
4. Commissioning After Long-Term Storage
• Remove all anti-corrosive metal protectant from
otherwise bare metal surfaces. Follow product manufac-
turers directions and warnings during surface protection
removal.
• Drain the reducer and refi ll it with the proper type and
amount of lubricant.
• Observe start-up and initial operation to make sure there
are no seal or gasket leaks, or unusual sounds, vibration or
heat rise during operation.
• Check the resistance of all motor and brake windings to
verify the integrity of the winding insulation and inspect
all terminal box openings and wire connection areas to
verify that all components are dry and free of corrosion.
