Filling in the oil
Only SEW‑EURODRIVE Service or specialists trained by SEW‑EURODRIVE are permitted to open the gear unit cover.
- Perform the steps described in chapter Preliminary work for inspection and maintenance.
- Let the device cool down sufficiently before touching it.
- However, the gear unit must still be warm, otherwise the high viscosity of excessively cold oil will make it more difficult to fill in the oil correctly.
- SEW‑EURODRIVE recommends filling in the new oil in the position depicted in the figure below.
- Do not mix different synthetic lubricants and do not mix synthetic and mineral lubricants! As standard lubricant use synthetic oil. Fill in new oil of the same type via the lower bore hole [2].
- The oil viscosity and type (synthetic) that are to be used are determined by SEW-EURODRIVE specifically for each order. This information is noted in the order confirmation and on the drive unit's nameplate.
- It is easier to fill in the oil when you also remove the upper breather plug [1] or breather valve installed there (air can flow out).
- For the required oil quantity, refer to the information on the nameplate or, depending on the mounting position, chapter Lubricant fill quantities.
- Re-insert the screw plug and the breather valve. The position of the breather valve depends on the mounting position of the drive unit. Observe the mounting position sheet in chapter Mounting positions.
- Touch up or renew the surface/anti‑corrosion coating.
