The Wacker Neuson Crank is a genuine OEM component designed for the CT36BDT and CT36BDT-E 915mm/36-inch walk-behind concrete trowels, the PT2B 50mm/2-inch centrifugal trash pump, and the B 3000 and B 5000 gasoline power units used with internal concrete vibrators. Sourced directly from Wacker Neuson, this crank is manufactured to the same specification as the original part fitted at the factory, ensuring a correct, direct installation without modification. Whether you are servicing a concrete finishing machine, a trash pump, or an internal vibrator power unit, part number is the verified OEM replacement that restores proper engine operation across all compatible platforms.
Key Features
- Genuine OEM Crankshaft Integrity — Manufactured to Wacker Neuson's original dimensional and material specifications, ensuring the correct stroke geometry and rotational balance for smooth engine operation.
- Direct Drop-In Replacement — Matches the original crank mounting interfaces and bearing journals on all listed models, allowing straightforward installation during engine rebuild or repair.
- Broad Cross-Family Fitment — Confirmed for CT36BDT and CT36BDT-E walk-behind trowels, PT2B trash pumps, and B 3000 and B 5000 gasoline power units, covering multiple equipment categories with a single part number.
- Restores Full Power Output — A correctly functioning crank maintains proper piston travel and compression, which is critical for consistent engine output whether driving a trowel, pump, or vibrator unit.
- Long-Term Engine Reliability — A worn or damaged crank causes vibration, loss of compression, and accelerated bearing wear; replacing it with a genuine OEM part protects the surrounding engine components from secondary damage.
The crank — or crankshaft — is the central rotating component of the engine that converts the up-and-down motion of the piston into the rotational power that drives the machine. It works in conjunction with the connecting rod, bearings, and flywheel to deliver smooth, consistent power to whatever the engine is driving, whether that is the rotor of a concrete trowel, the impeller of a trash pump, or a vibrator head through a flex shaft. When a crank becomes worn, cracked, or out of balance, the result is rough running, excessive vibration, loss of power, and eventual engine failure — making timely replacement essential to keep the machine performing as intended.
