4.4.3
Renewal of the interior preservation of the gear unit for longer periods of storage of the gear unit that has
not been taken into operation yet
If the gear unit is taken into operation at a point in time, when the maximum durability of the interior
preservation of the gear unit exceeds the durability as specified in Table 2 under item 4.4.2.1 or if it has
reached remaining durability period specified in item 4.4.2.2, the interior preservation of the gear unit must
be renewed following the expiration of the durability period.
4.4.3.1 Renewal of the gear unit interior preservation with "Castrol Corrosion Inhibitor N 213"
For the renewal of the gear unit interior preservation, the VCI gas discharging fluid
"Castrol Corrosion Inhibitor N 213" is recommended.
CAUTION
Risk of injury
Risk of injury to eyes or hands from chemically aggressive operating substances.
Wear suitable protection glasses and protection gloves.
Remove any spilled oil immediately using an oil binding agent.
Note
In this renewal of the gear unit interior preservation, it must be ensured that the ambient and gear unit
temperature is above 5 °C during filling.
The following control measures must be taken:
•
the pressure, suction and/or return lines are sealed with blind flanges.
•
The oil drain cocks on the gear unit and on the tilting pad thrust bearing chamber are sealed with screw
plugs.
•
The labyrinth seal on the output flange is sealed with the round cord hollow profile (13) and masked
airtight (see Figure 5 in item 4.4.3.2).
The following procedure is recommended:
•
Remove screw plugs that have been screwed in for transport instead of the air filter.
•
Fill gear unit with "Castrol Corrosion Inhibitor N 213" through the openings of the air filters.
Filling quantity: 1 litre per cubic metre of the entire free interior volume of the gear unit (to be enquired
from Siemens). The interior volume of the gear unit can be ascertained in approximation also by the
length x width x height of the gear unit.
Tilting pad thrust bearing chamber and gear unit chamber each have to be filled with half of the
preservative volume.
•
The vent holes of the air filter for the gear unit and the tilting pad thrust bearing chamber have to be
closed and sealed again with screw plugs (these must be replaced again at the start-up).
