The Wacker Neuson Woodruff Key is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard and traction control configurations. As a direct OEM replacement, the is manufactured to the same specifications as the original part, ensuring a correct, consistent fit within the drivetrain assembly. This key is confirmed compatible across multiple RD27 series machine configurations, making it a reliable choice for scheduled maintenance or unplanned repair. Verify your machine's model number before ordering to confirm fitment.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact original tolerances, ensuring the key seats fully in the shaft and hub keyways without play or slop.
- Direct Drivetrain Replacement — Drops into the existing keyway slot without rework, restoring proper torque transfer between shaft and mating component.
- Broad RD27 Series Coverage — Compatible with RD27-100 and RD27-120 models across standard hydrostatic vibratory roller and traction control configurations.
- Torque Integrity Restored — A worn or sheared Woodruff Key causes slippage between rotating components; replacing it promptly restores full power transmission and prevents secondary damage to the shaft or hub.
- Drivetrain Safety Compliance — A correctly seated key prevents unexpected relative rotation between shaft and sprocket or pulley, which is critical for safe, controlled roller operation.
A Woodruff Key is a small, semi-circular metal key that locks a rotating shaft to a hub, sprocket, gear, or pulley, ensuring both components turn together as a single unit. In a hydrostatic vibratory roller like the RD27 series, this key plays a critical role in maintaining positive torque transfer within the drivetrain. When a Woodruff Key shears or wears, the shaft can spin independently of the component it drives, resulting in loss of drive, vibration, or further damage to surrounding hardware — making prompt replacement essential.
