Wacker Neuson 0045036 Crankshaft

The Wacker Neuson Crankshaft is a genuine OEM Crankshaft designed for the BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, and BS65-V series vibratory rammers, as well as legacy BS500, BS600, and BS700 rammer models and BH 22, BH 23, BH 24, BH 55, and BH 65 series gasoline breakers. As a genuine Wacker Neuson OEM component, the is manufactured to the same specification as the original part, ensuring a correct fit and consistent engine performance. This crankshaft covers an exceptionally broad range of BS-family two-stroke and oil-injected rammer variants — including EU, high-altitude, variable-speed, and low-HAV configurations — making it a go-to stock item for rental fleets and service shops that maintain multiple Wacker Neuson units. Verify your model number and machine number against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original crankshaft tolerances, preserving correct stroke geometry, rod journal fit, and bearing seating critical to two-stroke and oil-injected engine timing.
• Drop-In Engine Replacement — Matches the original crank assembly interface in BS-series rammers and BH-series breakers; installs into the existing engine cases without case modification or re-balancing.
• Broad BS and BH Series Coverage — A single part number spans BS50-2, BS60-2, BS70-2, BS65-V, legacy BS500/600/700, oil-injected "-oi" and "-2i" variants, and BH 22 through BH 65 gasoline breakers — simplifying parts inventory across a mixed fleet.
• Restored Power Stroke Consistency — A worn or damaged crankshaft causes irregular percussion cycles, loss of impact energy, and increased vibration at the operator handles; a fresh 0045036 restores the full, metered power stroke the rammer or breaker was engineered to deliver.
• Engine Integrity Under High-Cycle Loading — Rammers and gasoline breakers subject the crankshaft to continuous high-frequency loads; using the correct OEM-spec crank maintains proper oil film distribution across rod and main bearings, reducing heat buildup and premature wear throughout the bottom end.

The crankshaft is the central rotating component of a two-stroke engine, converting the linear force of the piston's power stroke into the rotational motion that drives the rammer's exciter mechanism or the breaker's percussion system. In a vibratory rammer, this rotation ultimately produces the rapid, high-energy up-and-down foot movement that compacts cohesive soils and trench backfill. When a crankshaft develops wear on its rod journals, cracks, or out-of-round bearing surfaces, the result is increased vibration, loss of compression seal, audible knocking, and — if left unaddressed — catastrophic bottom-end failure. Replacing a worn crankshaft with the correct OEM part restores proper bearing clearances and ensures the engine runs at its designed power output and cycle rate.
