When should I change the oil in my Liebherr excavator?

Regular oil changes are important for all excavators, transfer machines and earth-moving machines. Below, we explain how this works.

The purpose of oil

Hydraulic oil is essential for Liebherr machines. The oil is pumped around the entire machine: the swivel motor, swivel pump, main pump, drive motors, and various cylinders. All parts work with the same oil, except for the final drive, the diesel engine, swing gearbox, and gearbox. These parts contain their own specific oil.

Hydraulic oil generally lasts for 6,000 operational hours. This varies greatly per machine and also depends on how the machine is used.

How can you check whether the oil is too old?

Although, as a precaution, oil is often replaced on time, replacing oil is expensive. That's why it is better to check whether the oil really needs replacing. Proceed as follows:

1.        Take a test sample.
2.        Send it to your maintenance workshop.
3.        Have them measure the iron values and viscosity.
4.        Change the oil if the values are too high

Iron values of your Liebherr machine

Wear is inevitable when using a machine. Wear causes fine iron particles to end up in the hydraulic oil. The more iron there is in the oil, the higher chance of wear. Have your oil replaced in time if the iron values are too high.

Viscosity

Viscosity provides information about the thickness of the oil. As the viscosity of the oil decreases, it loses its lubricating properties. That is why we measure the viscosity when we need to know more about the oil's shelf life.

Change the oil in time

If, after measuring the oil, it becomes clear that the oil needs to be replaced, do so as soon as possible to ensure that your Liebherr stays in top condition.
