The Wacker Neuson Crankshaft is a genuine OEM Crankshaft designed for BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series pumps. As a direct Wacker Neuson OEM part, the is manufactured to the same tolerances and material specifications as the original component installed at the factory — ensuring proper fit and function without guesswork. This Crankshaft is the correct replacement for operators running any of the covered BPS and A5000 series machines who need a confident, verified repair. Cross-check your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Grade Crankshaft Precision — Machined to exact journal tolerances, maintaining proper bearing clearances and rotation balance critical to engine longevity.
- Direct OEM Replacement — Drops into the engine casing using the same mounting points and dimensions as the original, requiring no re-machining or fitment adjustments.
- Broad BPS and A5000 Series Coverage — Confirmed fitment across BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B pump models.
- Restores Full Power Stroke Output — A correctly functioning crankshaft converts piston motion into clean rotational output; a worn or damaged crank causes vibration, power loss, and accelerated internal wear throughout the engine.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson OEM supply chain, so the part number, geometry, and material grade match what shipped with the machine originally.
The crankshaft is the central rotating component of the engine, converting the up-and-down motion of the piston into the rotational force that drives the pump. It must maintain precise balance and journal surface integrity to keep the engine running smoothly under load — even minor wear or damage to the crank journals accelerates bearing failure and leads to excessive vibration throughout the machine. When a crankshaft is worn, cracked, or seized, the engine loses power delivery and can suffer rapid secondary damage to connecting rods, bearings, and cylinder walls if not addressed promptly.
