Engine Liebherr D9306

Liebherr D9306 engine after overhaul – complete unit for quick installation

An overhauled Liebherr D9306 engine is available, prepared as a complete power unit ready to be installed in your machine. The engine has undergone a complete overhaul and full reconditioning, with a documented scope of work and tests on the test bench (dyno). It is a solution for users who expect reliability and minimal machine downtime.

Scope of overhaul and inspection

• Complete repair and overhaul – engine block, crankshaft, cylinder heads, liners, pistons, rings, bearings, oil pump and water pump reconditioned or replaced with new parts from reputable manufacturers.
• Injection system inspected – injection components after detailed diagnostics, refurbished or replaced and calibrated to the Liebherr D9306 engine parameters.
• Precision machining – crankshaft reground, cylinder heads machined, valves and guides replaced, leakage and clearances checked according to service data.
• Dynamometer tests – each unit is tested under load, confirming that the overhauled engine reaches factory power and torque parameters.

Applications of the Liebherr D9306 engine

The D9306 engine is used in many machines operating in harsh conditions. It can work as:

• engine for an excavator Liebherr and other brands with similar power ratings,
• engine for a wheel loader working in gravel pits, quarries and on construction sites,
• engine for a dump truck used in open-pit mines and aggregate handling,
• engine for a stationary machine, generator set or specialist equipment.

Thanks to its robust design and the full scope of overhaul, the unit is suitable for continuous operation, including in high dust levels and under heavy load.

Why choose an overhauled engine?

• Reliability after full overhaul – the overhauled engine is assembled using new or reconditioned components, within factory tolerances.
• Shorter downtime – the engine is available and ready for installation, reducing machine downtime compared to a long rebuild of the old unit.
• Optimized cost – compared to a brand-new engine, a ready overhauled engine lowers costs while maintaining high durability.
• Accessory adaptation – the possibility to convert and adapt the engine to a specific machine: different timing case, additional hydraulic pumps, alternators, compressors according to customer requirements.
