Visual inspection for leaks:
If leaks are suspected, the gear unit should be cleaned, the oil level checked (see Section 4.1)
and checked again for leaks after approx. 24 hours. If a leak is confirmed (dripped oil), the gear
unit must be repaired immediately. Please contact the NORD service department.
If the gear unit is equipped with a cooling coil in the housing cover, the connections and the
cooling coil must be checked for leaks. If there are any leaks, these must be repaired
immediately. Please contact the NORD service department.
Check for running noises
Checking the oil level:
See Section 4.1
Visual inspection of the rubber buffer
Gear units with rubber buffers (Option G or VG) and gear units with torque supports are
equipped with rubber elements. If these show damage such as tears to the rubber surface, the
elements must be replaced. Please contact the NORD service department.
Visual inspection of hose
Gear units with an oil level vessel (Option OT) have rubber hoses. If damage to the external
surface of the hoses as far as where they are inserted occurs, e.g. due to abrasions, cuts or
tears, they must be replaced. Please contact the NORD service department.
Visual inspection of the temperature sticker
(Only necessary for temperature class T4 or max. surface temperature < 135°C)
Danger!
Installation and maintenance work must only be performed when gear units are at a
standstill. The drive must be isolated and secured to prevent accidental start-up.
Danger!
The gear unit must be checked for leaks. Attention should be paid to escaping gear oil
and traces of oil on the exterior or underneath the gear unit. In particular, the radial
seals, cover caps, screw plugs, hoses and housing joints should be checked.
Danger!
If the gear unit produces unusual running noises and/or vibrations, this could indicate
damage to the gear unit In this case the gear should be shut down and a general
overhaul carried out.
