Wacker Neuson 5000176159 Lombardini Engine

The Wacker Neuson Lombardini Engine is a genuine OEM powerplant designed for the PT6LT, PT6LS, and PT6LS(I) series 6-inch centrifugal trash pumps. Sourced directly from Wacker Neuson, this engine carries the same OEM specification as the unit originally installed at the factory, ensuring a direct, like-for-like swap with no adaptation. Whether your PT6LT trailer-mounted pump or skid-mounted PT6LS has suffered a seized engine, catastrophic failure, or simply reached the end of its service life, part number is the correct replacement to bring the machine back to full operating capacity.

Key Features

• Genuine OEM Lombardini Sourcing — Supplied as an authentic Wacker Neuson OEM assembly, matched to the original Lombardini engine specification for the PT6 pump family — not a remanufactured or generic substitute.
• Direct-Fit Engine Swap — Engineered to bolt directly into the PT6LT, PT6LS, and PT6LS(I) pump frames, aligning with existing mounting points, drive coupling, and fuel system connections right out of the box.
• Broad PT6 Series Coverage — Fits the PT6LT trailer-mounted pump, the PT6LS skid-mounted 150mm/6-inch centrifugal trash pump, and the PT6LS(I) trash pump variant under a single part number.
• Full Pumping Capacity Restored — A correctly installed engine returns the pump to its rated flow and discharge performance — critical for high-volume dewatering, bypass pumping, and job-site drainage operations where output consistency matters.
• Fuel System Integrity — As a complete engine assembly, fuel system components are matched and sealed to OEM specification, reducing the risk of fuel leaks or delivery issues that could arise from mismatched aftermarket units on diesel-powered equipment.

The engine is the core power source of the PT6 trash pump, converting diesel fuel into the rotational force that drives the pump impeller. In a centrifugal trash pump of this size — handling up to 6-inch discharge volumes — the engine must sustain consistent torque output to move high volumes of water containing solids, debris, and slurry without cavitation or flow loss. When the engine degrades or fails, the pump produces no output, bringing dewatering or bypass operations to a complete stop. Replacing the engine with the correct OEM unit restores the pump to its designed performance envelope and extends the working life of the overall machine.
