The Wacker Neuson 5100067158 Woodruff Key is a genuine OEM Woodruff Key designed for the BPS series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications required for proper shaft and drive component alignment across the BPS lineup. Compatible models include the BPS1030B, BPS1030Bw, BPS1135B, BPS1135Bw, BPS1340B, BPS1340Bw, BPS1550B, BPS1550Bw, BPS2050B, and BPS2050Bw plate compactors. When it comes to a small but critical drivetrain component like this, using the correct OEM part ensures the drive assembly seats and locks exactly as intended.
Key Features
- Exact OEM Geometry — Machined to the precise profile required for correct seating in the shaft keyway, preventing slippage or misalignment under compaction load.
- Direct Drivetrain Fit — Drops into the shaft and hub keyway without modification, restoring the mechanical lock between rotating components as originally assembled.
- Broad BPS Series Coverage — A single part number covers the BPS1030B, BPS1135B, BPS1340B, BPS1550B, and BPS2050B families, including both standard and wide-base variants.
- Protects Shaft and Hub Integrity — A worn or missing Woodruff Key allows the hub to rotate independently on the shaft, causing rapid damage to both components; replacing it promptly prevents costly secondary failures.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component, ensuring the material grade and dimensional tolerances match the original production specification.
A Woodruff Key is a small, semi-circular metal key that locks a rotating component — such as a pulley, clutch drum, or drive hub — to its shaft, preventing the two from rotating independently of each other. In a vibratory plate compactor, the drivetrain depends on this connection to transfer engine power through to the exciter mechanism that drives compaction force. When the Woodruff Key shears or wears, the driven component slips on the shaft, causing a sudden loss of vibration output and potential damage to the shaft and hub keyway surfaces if the machine continues to run.
