5.2.4 Rubber buffer (Option: ED)
Gear units with an elastic torque support (Option ED) have rubber elements. If these show damage
such as tears to the rubber surface, the elements must be replaced. In this case, please contact
NORD Service.
5.2.5 Piping
5.2.5.1 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.
5.2.5.2 Hose lines (Option: LC, LCX, CS1, CS2, OT)
Hose lines are used as intake and pressure lines for lubricant circulation and for cooling units. In
addition, if an oil tank is present, this is connected to the gear unit with hose lines.
Hose lines are subjected to a natural ageing process due to external influences (e.g. UV radiation) to a
greater extent than pipes.
When checking hose lines, look out for leaks, cuts, cracks, porous areas and chafing. In such cases,
the affected hose lines must be replaced. Please contact the NORD Service department.
5.2.6 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.
5.2.7 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.
