The Wacker Neuson 5200016162 Woodruff Key is a genuine OEM component designed for the MS54 vibratory rammer. As a factory-sourced part, it is manufactured to the exact tolerances required for correct shaft-to-hub engagement in the rammer drivetrain. This key is a direct replacement for the original, ensuring a proper fit without the need for modification. Wacker Neuson's genuine OEM designation confirms this part meets the same specifications as the unit installed at the factory, giving you confidence in the repair from the first turn of the wrench.
Key Features
- Exact Dimensional Tolerancing — Manufactured to OEM spec for a precise shaft-slot fit, preventing slippage or play between mating components.
- Genuine OEM Sourcing — Factory-authorized part carrying Wacker Neuson's full OEM designation, not a generic substitute.
- Verified Rammer Fitment — Confirmed compatible with the MS54 vibratory rammer (280/11in shoe configuration), so you order with confidence.
- Drivetrain Integrity — A correctly seated Woodruff Key locks the drive component to the shaft, maintaining consistent power transfer throughout the compaction stroke.
- Fast, Low-Cost Restore — Replacing a worn or sheared key is one of the quickest ways to bring a rammer back to full working order without a major teardown.
A Woodruff Key is a small, semi-circular metal key that fits into matching slots cut into both a shaft and the hub of a mating component — such as a drive gear or flywheel — locking the two together so they rotate as one unit. In a vibratory rammer like the MS54, this key plays a critical role in transmitting engine power through the drivetrain to produce the percussive compaction stroke. When a Woodruff Key shears, wears, or works loose, the hub can spin independently on the shaft, causing immediate loss of drive, accelerated wear on both components, and potential secondary damage to the surrounding assembly. Prompt replacement with the correct OEM key restores the mechanical lock and protects the integrity of the shaft and hub.
