Filling in the oil

The gear unit cover may only be opened by the SEW‑EURODRIVE Service team or specialists trained by SEW‑EURODRIVE.

  1. Perform the steps described in the chapter Preliminary work for inspection and maintenance.
  2. WARNING! Risk of burns due to hot surfaces. Severe injury. 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.
  3. SEW-EURODRIVE recommends filling in the new oil at the position shown in the figure below.
  4. NOTICE! Filling in the wrong oil may result in significantly different lubricant characteristics. Damage to property. Do not mix different synthetic lubricants and do not mix synthetic lubricants with mineral lubricants! As standard lubricant use synthetic oil. Fill in new oil of the same grade via the lower bore [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, the product manual > chapter Lubricant fill quantities.
  5. 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 the product manual > chapter Mounting positions.
  6. Touch up or renew the surface/corrosion protection coating.
