6.5. THE FIRST OIL FILLING
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.
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 on
initial oil filling 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.
Units with horizontal shafts (QH ..) equipped with a motorbase M1 and M3 must be filled on
initial filling with a small quantity of oil 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 through lack of space between the motor base
and the gear unit upper face, the motor base should be raised following removal of the belt.
For gear units with M1 motor base the normal oil filling plug is located at the side of the output
shaft, opposite the side where the dipstick is located.
For gear units with M3 motor base the normal oil filling plug is located at the side of the
dipstick.
If the gear unit is filled with storage oil, it has to be drained and it may in some instances be
necessary to rince the gear unit with the selected oil before starting up. Check with the oil
supplier.
6.6. GREASE SELECTION
Use only high quality greases, with EP-additives and consistency NLGI-Grade 3.
Greases with EP-additives and consistency NLGI-Grade 2 may be used for regreasable
labyrinth type seals and grease lubricated lower bearing of the low speed shaft.
