Always refer to the certified dimensional drawing and stickers on the gear unit.
7.5. THE FIRST OIL FILLING (see fig. 5)
Fill units only after final installation, especially gear units with vertical downwards shafts, to prevent oil splashing
over drywell during handling.
Fill the gear unit exclusively through the oil filling opening which is provided in the inspection cover for
that purpose. In that way, all bearings are lubricated with fresh oil before start up.
Note :
- Additional oil filling of the bearing housing.
4-stage horizontal gear units with right angle shafts (QHR.4) and 3- and 4-stage vertical gear units
with right angle shafts (QVR.3 + QVR.4) require also an additional oil filling of the bearing housing.
See special sticker on gear unit. The additional oil quantity is mentioned on the certified drawing and
on the sticker.
- Oil filling of a gear unit with M1 or M3 motor base.
For gear units with horizontal shafts (QH ..) equipped with a motorbase M1 or M3 an additional small quantity
of oil must be added through the inspection cover located in the top face of the gear unit (see special
sticker on gear unit).
If easy access to the oil filler plug is prevented due to lack of space between the motor base and the gear unit
upper face, the motor base should be raised after removal of the belt.
The position of the oil filling plug is indicated by a sticker on the gear unit. Refer to to the certified dimensional
drawing.
