Engine Liebherr D9408

Liebherr D9408 engine after overhaul – ready for installation

We offer an industrial Liebherr D9408 diesel engine after a complete overhaul, prepared as a fully assembled power unit for construction and material-handling machines. The repaired engine is available from stock and can work as an engine for an excavator, wheel loader, dump truck or other heavy machine.

Scope of overhaul and engine configuration

• Complete engine overhaul – worn components (pistons, liners, rings, bearings, gaskets, oil pump) are replaced as part of a full overhaul.
• Cylinder heads and crankshaft – heads are machined, valves and guides are reconditioned, the crankshaft is checked and prepared for further operation in heavy-duty conditions.
• Fuel injection system – injectors and the injection pump are professionally repaired or replaced, with settings adjusted to the requirements of the machine.
• Cooling and lubrication systems – pumps, coolers and oil passages are checked to ensure the engine maintains stable operating temperatures and pressures.
• Dynamometer testing – each unit undergoes a load test on the dyno to confirm its operating parameters after the overhaul.

Application in machines

The Liebherr D9408 engine is used in heavy-duty machines where high torque and stable long-cycle operation are crucial – including crawler excavators, wheel loaders, articulated dump trucks and special-purpose machines. It performs well in continuous operation in quarries, crushing plants, recycling facilities and other industrial applications.

Service, diagnostics and support

• Construction machinery service – we provide comprehensive service for Liebherr units, from inspections to complete repair and overhaul of the engine.
• Diagnostics – we perform detailed diagnostics of the engine before and after the overhaul (combustion parameters, oil pressure, exhaust smoke).
• Mobile service – if needed, a mobile service team is available to travel directly to the machine on the construction site or at the plant.
• Spare parts – we provide access to original and aftermarket spare parts for the D9306–D9408 series, which facilitates subsequent maintenance and current engine repairs.
• Warranty support – the overhauled engine is covered by warranty, provided that the manufacturer’s recommendations and regular inspections are followed.

Availability, location and shipping

The Liebherr D9408 engine after overhaul is prepared for installation or adaptation to a specific machine. We support customers from the region including: Kraków, Małopolska, Podhale, as well as other parts of the country. Installation in our workshop, a visit from our mobile service team and shipment of the engine within Poland and abroad are all possible.

Why choose a Liebherr D9408 engine after overhaul?

• Short downtime – a ready overhauled engine allows you to quickly bring the machine back to work without waiting for a long on-site engine repair.
• Controlled costs – after a complete overhaul you know the exact scope of work and the price of the unit, which makes fleet budgeting easier.
• Flexible configuration – it is possible to adapt auxiliaries (timing case, hydraulic pumps, turbocharger, wiring harnesses) to a specific machine model.
• Technical support – we help select the right D9408 variant and prepare the unit so that installation is as close as possible to a “plug&play” fit.

FAQ – frequently asked questions

• Does the overhauled Liebherr D9408 engine deliver full power?
  Yes, before delivery to the customer the engine is started and tested on a dynamometer to confirm its performance after the overhaul.
• Can you match the engine to my machine?
  Yes, based on the old engine or data from the nameplate, we select the configuration and auxiliaries so that installation is as close as possible to „plug&play”.
• Do you also perform engine repairs at the customer’s site?
  In many cases we can offer both on-site engine repair and delivery of a ready overhauled unit together with installation.

Liebherr engines – brand and technology

Liebherr is an international engineering group originating from Germany, best known for manufacturing construction equipment, cranes, mining machinery and industrial components. For decades it has been developing its own diesel engines for heavy-duty applications, integrating them into excavators, loaders, dump trucks and other working machines.

Liebherr engines are designed for high durability, low fuel consumption and stable operation under heavy loads. This makes them a reliable choice for companies that expect predictable maintenance costs, good parts availability and service support throughout the machine’s entire operating life.
