Why does Liebherr loader service require expert knowledge?

The design of Liebherr wheel loaders (such as the popular L 550, L 556, L 566, and L 580 models) differs significantly from machines of other manufacturers. The heart of their drivetrain is a hydrostatic drive, which allows for smooth speed regulation and fuel consumption optimization. This system, while highly efficient, consists of precisely fitted components of power hydraulics from brands like Linde and Rexroth.

Servicing these systems rules out guesswork. Any attempts at repair without the appropriate engineering knowledge and diagnostic tools can lead to irreversible damage to piston pumps and hydraulic motors. At WIBAKO, we understand the specifics of these machines perfectly, which allows us to accurately locate and eliminate faults at their very source.

Scope of Liebherr Loader Service at WIBAKO

By dividing our staff into specialized teams – separately dedicated to power hydraulics and internal combustion engines – we guarantee comprehensive support in every area of the machine's operation.

1. Regeneration of power hydraulics

The hydraulic system is the circulatory system of every wheel loader. Our engineering team specializes in advanced diagnostics and major overhauls of:

• Hydraulic pumps and motors: We regenerate components from brands like Linde, Rexroth, and Liebherr's own proprietary designs. After assembly, every unit undergoes testing on a professional test bench.
• Hydraulic control valves: We eliminate internal oil leaks, restoring precision to operating movements and optimal working pressures.
• Hydraulic cylinders: We perform seal replacement, cylinder honing, and piston rod regeneration.

2. Major overhauls of Liebherr internal combustion engines

We possess unique competencies in the field of major and current repairs of Liebherr power units (including the D934, D936, D846 series). Our engine service includes:

• Computer diagnostics of engine operating parameters.
• Regenerating Common Rail fuel injection systems.
• Replacement of repair kits (crankshafts, pistons, liners, cylinder head regeneration).
• Tests on our own dynamometer: We have an engine dynamometer with a capacity of up to 500 HP. Every overhauled engine undergoes rigorous load tests, generating a clear chart of operating parameters that confirms the issue has been resolved.

3. Repair of drivetrains and axles

Wheel loaders are subjected to massive axial overloads. We service, regenerate, and replace worn drive axles, transfer cases, and final drives, eliminating play and restoring full traction of the machine.

Why should you trust WIBAKO?

The Google search engine, and above all business clients, rate machine service centers based on real experience, knowledge, and authority. Here are the parameters that distinguish WIBAKO on the Polish and European markets:

• Experience: We have been operating continuously for over 35 years. We have repaired thousands of construction machine components, which gives us an invaluable knowledge base regarding typical and unusual faults in Liebherr loaders.
• Experts: Our mechanics are qualified engineers with specialized education. We work according to original technical procedures and use specialized diagnostic software.
• Warranty: We provide a 12-month warranty on the internal combustion engine overhauls we perform. The client always receives full documentation from the load trials and tests upon request.
• Independent parts stock: We possess a huge, proprietary warehouse of spare parts – including over 50 complete combustion engines and hundreds of pumps and control valves. This allows for instant repairs "on the spot" or parts shipment under an exchange program, minimizing costly downtime on the construction site.

Mobile Liebherr loader service - help directly on the construction site

We understand perfectly that transporting a wheel loader weighing over a dozen tons to a stationary workshop generates high costs and logistical difficulties. That is why WIBAKO has a fully equipped fleet of mobile service vehicles.

Our mobile mechanics travel throughout the Małopolskie and Śląskie Voivodeships, and for larger assignments – across the entire country. At the site of the breakdown, we perform precise computer and hydraulic diagnostics. If possible, we resolve the issue on site. If advanced regeneration is necessary, we disassemble the damaged component (e.g., pump or motor), transport it to our modern workshop in Juszczyn, and after repair, we assemble and calibrate it directly on the client's machine.

How does the Liebherr loader repair process at WIBAKO look like?

To ensure maximum transparency and the highest quality of service, every repair in our service center is carried out according to strictly defined steps:

1. Contact and initial diagnosis: We analyze the reported symptoms by phone or email.
2. Delivery of the component or service arrival: You can deliver the machine/component in person to our headquarters in Kojszówka, order a pallet courier delivery, or call our mobile service.
3. Honest verification and cost estimate: We disassemble the component down to individual parts, measure the wear of the components, and prepare a detailed valuation for your approval.
4. Actual repair and final testing: After the cost estimate is approved, we proceed with the work. We use only proven, high-quality components, and the finished part is tested under operating load.
5. Machine handover and warranty: The fully operational component or complete machine returns to service, covered by full warranty care.
