The Wacker Neuson Woodruff Key 1/8 X 1/2, #3 is a genuine OEM component designed for the RS600 and RS800 series single drum walk-behind rollers. Sourced directly from Wacker Neuson, this Woodruff Key 1/8 X 1/2, #3 delivers an exact OEM fit within the drivetrain assembly, ensuring proper shaft-to-hub engagement without the need for fitting adjustments. Compatible across a broad range of RS-series configurations including the RS600, RS800A, RS800H, RS800V, and RSS800A models, this part covers the full walk-behind roller lineup. Verify your model and machine number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to Wacker Neuson's exact tolerances, this Woodruff key seats fully in its keyway slot, maintaining correct rotational lock between shaft and hub under load.
- Drop-In Drivetrain Replacement — Matches the original #3 profile and 1/8 x 1/2 inch dimensions, allowing straightforward installation into the existing keyway without recutting or shimming.
- Broad RS-Series Fitment — Confirmed for RS600, RS800A, RS800H, RS800V, and RSS800A walk-behind single drum vibratory rollers across multiple machine configurations.
- Prevents Shaft Slippage Under Compaction Load — A correctly seated Woodruff key locks the driven component to the shaft; a worn or sheared key causes slippage, loss of drum drive, and accelerated wear to mating components.
- Genuine Wacker Neuson OEM Part — Supplied as an authentic Wacker Neuson replacement, so the key material hardness and geometry match what the machine was built with from the factory.
A Woodruff key is a small semi-circular metal key that sits in a matching curved slot milled into a shaft, locking a gear, pulley, or hub in place so the two components rotate together as one unit. On the RS-series walk-behind rollers, it plays a critical role in the drivetrain by preventing the driven component from slipping on the shaft during the high-vibration demands of compaction work. When a Woodruff key shears or wears, the shaft spins freely inside the hub, causing an immediate loss of drive to the drum and potential secondary damage to the keyway itself if operation continues.
