The closure of the vent plug should be removed before commissioning and longer storage in order to prevent excess pressure in the gear unit, which could result in leaks developing in the gear unit. On delivery, gear units and geared motors, with the exception of types SK 11282, SK11382 and SK12382, are factory-filled with lubricant. This initial filling corresponds to a lubricant from the column for the ambient temperatures (normal version) in the lubricant table. The corresponding lubricants for other ambient temperatures are available at an additional charge.With mineral oil filling, the lubricant should be replaced every 10,000 operating hours or after two years. These periods are doubled for synthetic products. It is advantageous to replace the lubricants more frequently if the unit is operated in extreme conditions, such as high humidity, aggressive environment and high temperature.We recommend that replacement of the lubricants is combined with a thorough cleaning.
After changing the lubricant, and in particular after the initial filling, the oil level may change during the first few hours of operation, as the oil galleries and the hollow spaces only fill gradually during operation. The oil level is still within the permissible tolerance.
If at the express request of the customer, an oil inspection glass is installed at an additional charge, we recommend that the customer corrects the oil level after an operating period of approx. 2 hours, so that the oil level is visible in the inspection glass when the gear unit is at a standstill and has cooled down. Only then, is it possible to check the oil level by means of the inspection glass.
The gear unit is normally filled with mineral oil. Synthetic oil is available at an additional charge.
Comment: Do not mix synthetic and mineral lubricants! This also applies to disposal.
The stated filling quantities are for guidance only. The precise quantities vary depending on the exact gear ratio. When filling, always use the oil level screw as an indicator of the precise quantity of oil. The tables on pages A66-A73 show guideline amounts for the oil filling volume in litres, depending on the mounting position or configuration.
Gear unit types SK 11282, SK 11382, SK 12382 and SK 9096.1 are normally supplied without oil.
The gear unit oil is drawn in by a pump and flows through a heat exchanger. The oil is cooled by an air stream which is generated by a fan. The oil is then returned to the housing from the heat exchanger.
The temperature is controlled by a thermostat. Temperature monitoring is recommended.

As standard in the installation position M4, large parallel shaft gear units of size SK9282 and larger are equipped with an oil level tank ( A45).
Gear units with a motor or input shaft mounted vertically upright have a high oil level for lubricating the 1st gear unit stage. The use of an optional oil expansion chamber for the vertical mounting position M4 (A59) prevents the possible leakage of oil from the vent plug if oil foaming occurs.
NORD therefore strongly recommends that oil expansion chamber be used for gear ratios iges < 20 and for helical gear units size SK 42 and higher, for parallel shaft gear units SK 4282 to SK 8282 and higher, and for bevel gear units size SK 9042.1 and higher is the vertical mounting position M4 is used. Otherwise, no warranty is accepted.
Even for smaller size gear units and other gear unit types such as helical worm gear units sNORD strongly recommends the use of an oil expansion vessel for gear ratios iges < 20 and motor speed greater 1800 min-1 (87 Hz characteristic curve).

Oil storage tanks are located above the gearbox and increase the overall gearbox oil level. As all rotating components are completely below the surface of the oil, oil foaming is prevented. In addition, even with vertical designs, all bearings are lubricated in an oil bath.
Oil storage tanks are larger than oil expansion chambers and due to the additional vent pipes have two oil pipes which connect the oil storage tank to the gearbox. The oil level should be checked in the oil storage tank .NORD strongly recommends that oil storage tanks are used for large parallel shaft gear units SK 9282 to SK 2382 when the vertical mounting position M4 is used (A59). Otherwise, no warranty is accepted.
As standard, the oil storage tank is included as a kit which comprises the necessary oil lines, fixing material and assembly instructions. This enables the gear unit to be transported more cheaply and safely. In addition, the position of the oil storage tank can be determined on site during assembly. We will be glad to provide detailed information regarding the positioning possibilities and dimensions of the oil storage tank on request (WN 0-521 31).
As standard, the parallel shaft gear unit types SK9282 / SK9382 and SK10282 / SK10382 are supplied filled with the quantity of oil stated on page A60. On commissioning, the oil storage tank requires an additional quantity of approx. 30 litres of oil in order to maintain its recommended level. The standard delivery is made without this additional quantity of oil. However, a suitable container of oil can be supplied on request, subject to an extracharge.
As standard, the parallel shaft gear unit types SK11282 / SK11382 and SK12382 are supplied without oil. With the use of an oil storage tank, the necessary quantity of oil is increased by approx. 40 litres compared with the quantity stated on page A68-69

Installation positions - nomenclature For gear units and geared motors, NORD specifi es six installation positions from M1 to M6 as shown in the following diagrams. The relevant installation position must be stated when ordering.Changes to the installation position require adjustment of the quantity of oil, and often other measures such as the installation of encapsulated roller bearings. Damage may result if the necessary measures are not observed. Tilted installation positions between the 6 basic positions are possible. Please contact us.The versions, with the position of the oil level plug, the vent plug and the oil drain plug can be found on A60
