•
Close and seal the vent hole for the tilting pad thrust bearing chamber (11) with a screw plug again.
•
The lower oil drain cock on the gear unit (7) must be provided and sealed with a screw plug.
•
If not already done, close ventilation of the sealing cap (1).
Note
Before the start-up of the gear unit, the measures according to section 7.1 and 7.2 have to be carried
out.
4.4.3.3 Renewal of the interior preservation of the gear unit using the oil-supply system
The prerequisite for this is that the gear unit is still underneath the mill and connected to the oil-supply
system. "Castrol Alpha SP 220 S" or "Tribol 1390" can be used as preservative agent. The oil level must
never be below the MIN mark on the oil level indicator of the main gear unit, the tilting pad thrust bearing
chamber and/or on the oil-supply system (if the model has a tank, also see the operating manual of the
oil-supply system). For this purpose, the oil-supply system has to be switched on and the gear unit must
be turned without load (at least 1 rotation on the output shaft). The oil must be drained, the gear unit and
oil-supply system be closed, masked and sealed airtight. Air filters have to be replaced for sealing caps
and be sealed. The gear unit has to be sealed airtight with a round cord hollow profile between the gear
unit housing and the output flange. The labyrinth seals on the input shaft and on the output flange must be
masked airtight within 1 hour.
Note
Clean the air filters thoroughly (see item 10.3) and keep them in a safe place (these will be required
when starting up again).
