The Wacker Neuson 5100056809 is a genuine OEM Woodruff Key designed for the BPS series single-direction vibratory plate compactors, including the BPS1030A, BPS1135A, and BPS1340A models in both US and EU configurations. As a genuine OEM component, it is manufactured to the exact specifications of the original part, ensuring a correct, trouble-free installation. This key fits multiple variants across the BPS lineup, including standard and wide-plate Aw configurations, as well as the BPS1340Aws. Confirm your model number before ordering to ensure this is the correct key for your machine.
Key Features
- Genuine OEM Specification: — Manufactured to the precise dimensional tolerances required for proper shaft-to-hub engagement in BPS series plate compactors.
- Drop-In Installation: — Seats directly into the existing keyway slot without recutting or modification, maintaining the correct rotational alignment between mating components.
- Broad BPS Series Coverage: — Compatible with BPS1030A, BPS1135A, and BPS1340A models across US and EU variants, including standard, wide-plate (Aw), and Aws configurations.
- Protects Drive Components: — A correctly fitted Woodruff Key prevents shaft slippage and preserves the drive connection between rotating components, keeping compaction output consistent.
- Critical Drivetrain Safety: — A worn or missing key allows the driven component to spin free on the shaft, which can cause sudden loss of compaction force and accelerated damage to surrounding drivetrain parts.
A Woodruff Key is a small, semi-circular metal key that fits into a matching slot machined into a shaft and a hub, locking the two together so they rotate as one unit. In a vibratory plate compactor, it is typically used to secure components such as a pulley or clutch drum to the engine or exciter shaft, transmitting the rotational force that drives compaction. When the key shears or wears, the shaft and hub rotate independently, resulting in lost drive, erratic plate behavior, and potential damage to the shaft keyway itself if not addressed promptly.
