The Wacker Neuson is a genuine OEM Key 4.7 X 30 designed for the PT2Y 50mm/2-inch centrifugal trash pump and the VPY1740 and VPY1750 diesel vibratory plate compactors. As a factory-sourced component, it is manufactured to the exact tolerances required for proper shaft-to-hub engagement across all compatible models. This OEM designation means the matches the original specification installed at the factory — no guesswork on sizing or fitment. Whether you are servicing a PT2Y trash pump or a VPY1750 diesel plate, this key ensures the rotating assembly functions as intended.
Key Features
- OEM Dimensional Accuracy — Manufactured to the precise 4.7 x 30 profile required for correct torque transfer between shaft and hub, eliminating the risk of slippage or premature wear from an undersized key.
- Drop-In Shaft Keyway Fit — Engineered to seat fully in the keyway slot without filing or shimming, allowing straightforward installation during pump or plate drivetrain service.
- Cross-Platform Compatibility — A single part number covers the PT2Y centrifugal trash pump and the VPY1740 and VPY1750 diesel vibratory plate compactors, making it a practical stock item for mixed fleets.
- Drivetrain Integrity — A correctly fitted woodruff or parallel key locks the rotating component to the shaft so power is transmitted without slip; a worn or missing key causes immediate loss of drive and accelerated shaft damage.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5000073669 carries the full OEM part number traceability expected for warranty-period and scheduled maintenance repairs.
A drive key is a small rectangular or profile-cut piece of hardened metal that fits into matching slots — called keyways — machined into both a shaft and the hub of a rotating component such as an impeller, pulley, or eccentric. Its job is to lock those two parts together rotationally so that torque from the engine or motor is transferred without any relative slipping between them. When a key shears, deforms, or works loose, the driven component spins freely on the shaft, the machine loses output immediately, and the keyway surfaces on both the shaft and hub can be damaged — turning a low-cost consumable replacement into a far more expensive shaft or housing repair.
