The Wacker Neuson Crankshaft is a genuine OEM Crankshaft designed for a broad range of Wacker Neuson walk-behind concrete trowels, single-direction vibratory plate compactors, reversible vibratory plate compactors, and auxiliary power units. This is a direct factory-sourced component manufactured to the same specification as the original part it replaces. Verified fitment spans CT30 and CT36 series walk-behind trowels, WP1540 and WP1550 vibratory plates, VPA and VPG series vibratory plates, BPU 2440A and BPU 2450A reversible plates, the PT2A trash pump, and A5000 gasoline power units, among others. Confirming your model number and machine number before ordering ensures correct application.
Key Features
- Genuine OEM Precision Tolerance — Manufactured to Wacker Neuson's original engineering specification, maintaining the exact journal dimensions and counterweight balance required for smooth, vibration-free engine operation.
- Drop-In Engine Replacement — Matches original bearing journals, taper dimensions, and keyway geometry so it installs directly into the engine cases without machining or modification.
- Wide Cross-Family Fitment — Covers CT30 and CT36 walk-behind trowels, WP1540/WP1550 vibratory plates, VPA/VPG plate series, BPU 2440A/2450A reversible plates, PT2A trash pump, and A5000 power units.
- Restored Engine Output — A worn or damaged crankshaft causes power loss, excessive vibration, and accelerated bearing wear; replacing it with part 5000071641 restores full engine stroke and power delivery.
- Long-Term Internal Engine Integrity — Correct crankshaft geometry protects connecting rod bearings, main bearings, and seals from premature failure caused by runout or imbalance.
The crankshaft is the core rotating component of a small gasoline engine. It converts the linear up-and-down motion of the piston into the rotational force that drives the machine's working components — whether that is the spider assembly on a concrete trowel, the eccentric shaft on a vibratory plate, or an impeller on a pump. If the crankshaft develops wear on its bearing journals, becomes bent from impact, or suffers damage to the connecting rod pin, the engine will run roughly, lose power, or fail to run at all. Replacing a failed crankshaft with Wacker Neuson part 5000071641 restores correct engine geometry and protects surrounding internal components from further damage.
