E-28 | WG20 Geared Motors
14. Lubricants
If a special agreement regarding the lubricant is not reached, the gear units shall be delivered factory-lled (see table
below marked grey). The specied gear ll amount and type is stated on the gear unit nameplate. The ll amount and oil
type can be different at special applications.
The following lubricant table shows the lubricants that are approved for WG20 gear units.
For helical, parallel shaft and helical bevel gear units at ambient temperatures -10 °C to +60 °C (14 °F to 140 °F)
Do not mix different types of lubricant!
Lubricants for other ambient conditions on request. Food proofed and biodegradable lubricants on request.

Remove dust deposits:
Remove any layers of dust that have accumulated on the gear unit. If the gear unit design included a protection cap, remo-
ve it and clean it too. Then reinstall the protection cap (see page E-22).
Change the shaft seals:
When changing the shaft seal, make certain that, depending on the design, a sufcient deposit of grease is present be-
tween the dust lip and the sealing lip.
When using double seals, ll one-third of the space between them with grease.
Oil change:
Let the gear cool down before beginning with the work! The oil has to be warm to make a complete emptying easier (poor
ow characteristics).
1. Put an appropriate container under the air vent and oil drain plug.
2. Remove the air vent and oil drain plug.
3. Let the oil drain completely.
4. Turn the plug in again completely.
5. Fill in the prescribed amount of oil over the vent plug (oil ll capacity see gear nameplate, permitted lubricants see page
E-28).
6. Tighten the vent plug completely again.
7. Dispose the used oil according to applicable regulations.
General overhaul:
The general overhaul is to be performed by the producer or by an authorised service partner.
Adjustment of air gap: see page E-35.
Nachträgliche Lackierung: Wird das Getriebe nachträglich neu lackiert, müssen Wellen, Wellendichtringe, Montage-
ächen, Gummibauteile, Entlüftungsventile, Ölschaugläser, Typenschilder und Aufkleber frei von Farben, Lacken und
Lösungsmitteln bleiben, um Beschädigungen und Unlesbarkeit zu vermeiden.
