Checking the oil consistency
INFORMATION

A detailed and reliable examination of the oil consistency is not possible with the naked eye. If you are unsure whether the oil is in good condition or whether an oil change is required, we recommend performing a laboratory analysis of the oil.
SEW-EURODRIVE offers a laboratory analysis in which the oil is checked for wear, water, and contamination. Furthermore, the viscosity, acid value, and additive content of the oil is checked. For this purpose, contact SEW‑EURODRIVE.
Proceed as follows to check the oil consistency:
- Allow the gear unit to cool down below 50 °C before you start working on it.
- Start the gear unit for a short time for the oil to mix with suspended particles.
- Determine the oil drain and place a clean and dry container underneath.
- Slowly open the oil drain and drain some oil.
- Close the oil drain valve.
- Check the oil consistency:
- Check the drained oil for appearance, color, and contamination.
- If the oil sample is severely contaminated, e.g. water, cloudiness, change in color, dirt, consult a specialist to find out the cause.
