5.2.6 Visual inspection of the rubber elements of the elastic torque arm (Option: ED)
If these show damage such as tears to the surface, the rubber elements must be replaced. In this
case, please contact NORD Service.
5.2.7 Visual inspection of cables
5.2.7.1 Piping (Option: LC, LCX, OT)
The piping of lubrication circulation systems or vent lines for full oil level in combination with oil level
tanks must be checked for leaks.
The affected pipes must be replaced in case of leaks. In this case, please contact NORD Service.
5.2.7.2 Hose lines (Option: LC, LCX, CS1-X, CS2-X, OT)
Hose lines are used as intake and pressure lines for lubricant circulation and for cooling units. An oil
reservoir tank can also be connected to the gear unit via hoses.
Hoses are subjected to a natural ageing process due to external influences, e. g. due to UV radiation.
Check the hoses and screw connectors for leaks, cuts, tears, porous areas and chafing. In case of
damage, the hoses must be replaced. Please contact the NORD service department.
5.2.8 Oil filter (Option: CS1-X, CS2-X, LC/LCX)
As standard, the oil filter is equipped with a visual contamination indicator. It is recommended that the
filter element is replaced at the latest after an operating period of one year.
The filter element must be replaced immediately if the contamination indicator triggers. Refer to the
relevant manufacturer's documentation for further information.
5.2.9 Remove dust
Dust layers on the gear unit housing and on the fan blades degrade the cooling performance and lead
to overheating. Remove dust deposits. For ribbed gear unit housings, special care must be taken that
the spaces between the ribs are cleaned at regular intervals.
