Liebherr excavator service – professional repair and diagnostics at WIBAKO

Liebherr excavators are synonymous with reliability, technological innovation, and massive power on construction sites, in mines, and during roadworks. To ensure these advanced machines work at peak efficiency and without costly downtime, they require professional technical support. As the oldest independent Liebherr machine service in Poland, WIBAKO has been delivering comprehensive repair, diagnostic, and regeneration services for equipment from this legendary brand for over 35 years. Find out why professional Liebherr excavator service is an investment that guarantees maximum business continuity.

Why does Liebherr excavator service require top-tier specialization?

Modern Liebherr wheeled and crawler excavators (such as the popular Liebherr A904, R914, or the powerful units of the R934 and R944 series) are highly complex mechanical, hydraulic, and electronic systems. Attempting repairs at general workshops without proper diagnostic facilities often results in worsening the fault and multiplying costs.

In the hydrostatic systems of Liebherr machines, components from renowned brands such as Linde or Rexroth play a key role. Correct diagnosis and servicing of these elements require deep engineering knowledge. The most common issues excavator owners contact us with include:

Comprehensive power hydraulics – the heart of your excavator

The hydraulic system is the circulatory system of every construction machine. At WIBAKO, a dedicated team of highly qualified engineers and hydraulic specialists handles the repair of Liebherr power hydraulics. We specialize in advanced diagnostics and complete regeneration of components such as:

Importantly, we do not work blindly. We have advanced, professional test benches for power hydraulics. Every regenerated component leaves our facility only after passing rigorous tests under real load conditions, giving you 100% confidence that the component is fully functional.

Liebherr internal combustion engine overhauls with professional dyno testing

The heart of Liebherr machines consists of their reliable power units, including the popular D934 and D936 series engines. We perform both routine repairs and major overhauls of internal combustion engines. Our unique market advantage is our own engine dynamometer supporting capacities up to 500 HP.

Thanks to this, we can test every unit after an overhaul under full, real-world operating load. We check pressure, temperature, and power parameters, eliminating the risk of any defects before installing the engine back in the excavator. For clients where time is of the essence, we also offer ready-to-go, used, or fully remanufactured Liebherr internal combustion engines available immediately for exchange.

Mobile Liebherr excavator service – support directly on the construction site

We understand that every day of machine downtime on a construction site translates to massive financial losses. That is why WIBAKO offers professional mobile service for Liebherr machines. Our fully equipped service vehicles, operated by experienced mechanics, travel directly to the breakdown location – whether you work in Lesser Poland or other regions of the country.

As part of our mobile service, we offer:

Massive spare parts warehouse – repairs without unnecessary waiting

One of the biggest barriers to fast construction machinery service is waiting for parts. At WIBAKO, this problem practically does not exist. We have a massive warehouse facility where over 50 internal combustion engines, 200 hydraulic pumps, axles, final drives, gearboxes, and thousands of smaller spare parts – both new, used, or remanufactured – are available off the shelf. This allows us to reduce repair times to an absolute minimum.
