Storing the gear unit
For short-term storage before commissioning, please observe the following:
Store in the fitting position (see Section 6.1) and secure gear units against falling
Lightly grease bare metal housing surfaces and shafts
Store in dry rooms
Temperature must not fluctuate beyond the range of –5 oC to +50 oC
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
3.2 Long-term storage
Note!
For storage or standstill periods in excess of 9 months, Getriebebau NORD recommends the
long-term storage option. With the long-term storage option and 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 (see Section 6.1) and secure gear units 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 agents added to the gear oil. (See label on gear unit)
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 must not fluctuate beyond the range of –5 oC to +40 oC
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
If the storage or standstill period exceeds 2 years or the temperature during short-term
storage greatly deviates 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.

3. Storage, Preparation,
Installation
-10- B1000 www.nord.com
3.3 Preparing for installation
The drive unit must be inspected and may only be installed if no transportation damage or leaks
are visible. In particular the radial seals and the sealing caps must be inspected for damage.
In applications where an incorrect rotational direction may result in damage or potential risk, the
correct rotational direction of the drive shaft is to be established by test running the drive when
uncoupled and guaranteeing such for subsequent operation.
Gears with integrated return stops are marked with arrows on the driven/driving sides. The
arrows point in the rotation direction of the gear unit. It must be ensured, when connecting the
motor and during motor control, that the gear unit can only operate in the rotation direction, e.g.
by means of a rotary field test. (For further details, please refer to Catalogue G1000)
Attention!
With gear units with an integrated back stop, switching the drive motor to the blocked rotation
direction, i.e. incorrect rotation direction, can lead to gear damage.
Ensure that no aggressive or corrosive substances are present in the area surrounding the
installation site or are subsequently expected during operation, which attack metal, lubricants or
elastomers. In case of doubt, please contact Getriebebau NORD and take the recommended
action.
Oil expansion tanks (Option OA) must be fitted in accordance with the attached works standard
WN 0-530 04. For gear units with an M10x1 vent plug, works standard WN 0-52135 must be
observed.
Oil expansion tanks (Option OA) must be fitted in accordance with the attached works standard
WN 0-521 30.
If a vent plug is fitted, the sealing cord must be removed from the vent plug before
commissioning. Position of the vent plug: see Section 6.1.
Figure 3-1: Activating the vent plug
If in case of drive units with the option DR the pressure vent is not fitted, the vent plug must be
replaced with the supplied pressure vent before commissioning. This is achieved by screwing
out the vent fitting and replacing it with the pressure vent and seal (refer to Section 6.2 for torque
values). Double gear units consist of two single units and are equipped with 2 oil chambers and
2 pressure vents.
Figure 3-2: Removing vent plug and fitting the pressure vent

3. Storage, Preparation,
Installation
www.nord.com B1000 -11-
3.4 Installing the gear unit
The eyebolts screwed into the gear units must be used during installation. The safety
notes in Section 1.4 must be observed.
The base and/or flange to which the gear unit is fitted should be vibration-free, torsionally strong
and flat. The smoothness of the mating surface on the base or flange must be according to
tolerance clad K of DIN ISO 2768-2. All contamination to the bolting surfaces of gear unit and
base and/or flange must be thoroughly removed.
The gear unit must be precisely aligned with the drive shaft of the machine in order to prevent
additional forces from being imposed on the gear unit due to tension.
Welding of the gear unit is prohibited. The gear unit must not be used as the earth connection for
welding work, as this may cause damage to the bearings and gear wheels.
The gear unit must be installed in the correct configuration (see Section 6.1) (UNIVERSAL
gear unit types SI and SIS are independent of the configuration). For changes to the
installation position, the vent plug and the oil level must be modified (see Section 6.1).All
gear unit feet and/or all flange bolts on each side must be used. Bolts must have a minimum
quality of 8.8. The bolts must be tightened to the correct torques (refer to Section 6.2 for torque
values). Tension-free bolting must be ensured, particularly for gear units with a foot and flange.
Danger!
To ensure that the gearbox does not get too warm and to avoid injury to persons,
observe the following during installation:
The surfaces of gear units or geared motors may become hot during or shortly after
operation. Attention: danger of burns!! Protection against accidental contact may need to
be installed.
With geared motors, the cooling air of the motor fan must be able to flow unobstructed
onto the gear unit.

3.5 Fitting hubs on the gear shafts
Attention!
Do not subject the gear unit to harmful axial forces when fitting the hubs.
Drive and driven elements, e.g. coupling and chain-wheel hubs must be mounted onto the drive
and driven shaft of the gear unit using suitable pullers that will not apply damaging axial forces
onto the gear unit. In particular, do not hit the hubs with a hammer.
Use the end thread of the shafts for pulling. Fitting can be aided by coating the hub with lubricant
or heating it up to approx. 100oC beforehand.
Figure 3-3: Example of a simple pulling device
Danger!
Drive and driven elements, such as belt drives, chain drives and couplings must be fitted
with contact protection.
Drive and driven elements may only subject the drive units to the maximum radial forces
FR1 and FR and axial forces FA1 and FAas specified in the catalogue. Observe the correct
tension, particularly on belts and chains. Additional loads due to unbalanced hubs are not
permitted. The radial force must be applied to the gear unit as closely as possible.
3.6 Fitting push-on gear units
Attention!
The bearings, gear wheels, shafts and housing may be damaged by incorrect fitting.
The push-on gear unit must be fitted onto the shaft using a suitable puller, which will not exert
damaging axial forces on the gear unit. In particular, do not hit the gear unit with a hammer.
Assembly and subsequent dismantling is aided by applying an anti-corrosive lubricant to the
shaft before fitting.

3.7 Fitting shrink discs
Figure 3-10: Hollow shaft with shrink disc
Attention!
Do not tighten bolts if the solid shaft is not inserted!
Assembly sequence:
1. Remove any transport securing devices.
2. Loosen but do not remove tightening bolt and tighten gently by hand until there is no play
between the flanges and the inner ring.
3. Slide the shrink disc onto the hollow shaft until the outer clamping flange is flush with the
hollow shaft. The shrink disc is easier to slide on if the bore of the inner ring is lightly
greased.
4. Prior to mounting, grease the solid shaft only in the area which will later come into contact
with the bronze bush in the hollow shaft of the gear unit. Do not grease the bronze bush, in
order to prevent grease penetrating the area around the shrink connection.
5. The hollow shaft of the gear unit must be completely de-greased and completely
free of grease.
6. In the area of the shrink connection the solid shaft of the machine must be degreased and
completely free of grease.
7. Insert the solid shaft of the machine into the hollow shaft so as to completely fill the area
around the shrink connection.
8. Position the clamping flange by gently tightening the bolts.
9. Tighten the bolts successively in a clockwise direction by several turns – not crosswise –
with approx. ¼ rotation per turn. Tighten the bolts with a torque wrench to the torque
indicated on the shrink disc.

10. When the tensioning bolts have been tightened, there must be an even gap between the
clamping flanges. If this is not the case, the gear unit must be dismantled and the shrink disc
connection checked for correct fit.
Danger!
Risk of injury from incorrect mounting and dismantling of the shrink disc.
Dismantling sequence:
1. Loosen the bolts successively in a clockwise direction by several turns with approx. ¼
rotation per turn. Do not remove the bolts from their thread.
2. Loosen the clamping flanges from the cone of the inner ring.
3. Remove the gear unit from the solid shaft of the machine.
3.8 Fitting the covers
Danger!
Shrink discs and exposed rotating shaft ends require contact guards in order to prevent
injuries. A cover (Option H and Option H66) can be used as a guard. If this does not achieve
sufficient protection against contact according to the required protection type, the machinery
and plant constructor must ensure this be means of special attached components.
All fixing screws must be used and tightened to the correct torque. (See Section 6.2 for torque
values) With Option H66 covers, lightly press in the cover cap by means of light hammer blows.

Assembly procedure to attach a standard motor to the IEC adapter (Option IEC)/NEMA adapter
1. Clean motor shaft and flange surfaces of motor and adapter and check for damage.
Mounting dimensions and tolerances of the motor must conform to DIN EN 50347/NEMA
MG1 Part 4.
2. Push the coupling sleeve onto the motor shaft so that the motor parallel key engages into
the groove in the sleeve on tightening.
3. Tighten the coupling sleeve on the motor shaft in accordance with the motor manufacturer’s
instructions until it touches the collar. With motor sizes 160, 180 and 225, any spacer
bushes must be positioned between the coupling sleeve and the collar. With standard helical
gear units, dimension B between the coupling sleeve and the collar must be observed.
Certain NEMA adapters require the adjustment of the coupling in accordance with the
specifications indicated on the adhesive plate.
4. Secure the coupling half with the threaded pin. The threaded pin must be coated prior to use
with a securing lubricant e.g. Loctite 242, Loxeal 54-03 and tightened to the correct torque.
(See Chapter 6.2 for torque values)
5. Sealing of the flange surfaces of the motor and the adapter is recommended if the motor is
installed outdoors or in a humid environment. The flange surfaces of motor and adapter
must be completely coated with surface sealant Loctite 574 or Loxeal 58-14 prior to
mounting so that the flange seals after mounting.
6. Mount the motor to the adapter, do not forget to fit the gear rim or the sleeve. (See Figure 3-12)
7. Tighten the adapter bolts to the correct torque. (See Chapter 6.2 for torque values)

Attention!
For retrospective painting of the gear unit, the radial seals, rubber elements, pressure venting
valves, hoses, type plates, adhesive labels and motor coupling components must not come
into contact with paints, lacquers or solvents, as otherwise components may be damaged or
made illegible.
3.11 Fitting the cooling coil to the cooling system
Cutting ring screw threads (see Item 1, Figs. 3-13) are located at the casing cover for the
connection of a pipe with an external diameter of 10 mm according to DIN 2353. Remove the
drain plug from the screw neck prior to assembly to avoid any contamination of the
cooling system.The screw necks should be connected with the coolant circuit, which must be
provided by the operator. The flow direction of the coolant is irrelevant.
Make sure not to twist the screw necks during or after assembly as the cooling coil may be
damaged (see Item 3, Fig. 3-13). You must ensure that no external forces act on the cooling coil.

4. Commissioning
4.1 Checking the oil level
The oil level must be checked prior to commissioning. See Section 5.2.
4.2 Activating the automatic lubricant dispenser
Some gear unit types with standard motor (Option IEC/NEMA) have an automatic lubricant
dispenser for the rolling bearings. This dispenser must be activated prior to commissioning. The
cartridge case cover has a red information sign for the activation of the lubricant dispenser.
Activating the Automatic Lubricant Dispenser:
1. Loosen and remove cylinder bolts M8x16 (1)
2. Lift off cartridge case cover (2)
3. Insert activation screw (3) into the lubricant dispenser (5) until the lug (4) breaks off at
the defined fracture point
4. Refit cartridge case cover (2) and fasten using cylinder bolt (1). (See Chapter 6.2 for
torque values)
5. Mark activation date on the adhesive plate (6) indicating month/year

4.3 Operation with lubricant cooling
Water cooling
Caution!
The drive may only be commissioned after the cooling spiral has been connected to the
cooling circuit, and the cooling circuit has been put into operation.
The coolant must have a similar thermal capacity as water (specific thermal capacity at 20°C
c=4.18 kJ/kgK). Industrial water without any air bubbles or sediments is recommended as a
coolant. The water hardness must be between 1° dH and 15° dH, and the pH value must be
between pH 7.4 and pH 9.5. No aggressive liquids should be added to the coolant!
The coolant pressure must not exceed 8 bar. The required quantity of coolant is 10
litres/minute, and the coolant inlet temperature should not exceed 40°C; we recommend
10°C.
We also recommend fitting a pressure reducer at the coolant inlet to avoid any damage due to
excessive pressure.
If there is a danger of frost the operator should add a suitable anti-freeze solution to the cooling
water.
The temperature of the cooling water and the cooling water flow rate must be supervised
and ensured by the operator.
Air/Oil cooler
This version and all important data concerning the air/oil cooler can be obtained from Catalogue
G1000, or contact the manufacturer of the cooling unit.
4.4 Running-in time for the worm gear unit
Note!
In order to achieve maximum efficiency of the worm gear unit, the gear unit must be subjected
to a running-in period of approx. 25 h – 48 h under maximum load.
There may be a reduction in efficiency before the running-in period is complete.
