The Wacker Neuson Woodruff Key 4 X 6.5 is a genuine OEM component designed for a wide range of Wacker Neuson compaction equipment, including the RD25 hydrostatic double drum roller, RS800H single drum vibratory roller, DPU 2870, DPU 2950, DPU 2960, and DPU 2970 reversible vibratory plates, and DPS3050 and DPS3060 single-direction vibratory plates. As a direct OEM replacement, part is manufactured to the exact tolerances required to maintain proper shaft-to-hub alignment and torque transfer in your machine. Sourced directly from Wacker Neuson, this key ensures correct seating and retention in the keyway without guesswork or fitment issues. Keep a spare on hand — this small but critical drivetrain component is a common service item during shaft and drive assembly work.
Key Features
- Exact OEM Tolerancing — Machined to precise dimensional specs so the key seats fully in the keyway and transmits torque without slop or fretting.
- Direct Shaft Replacement — Matches the original 4 x 6.5 mm profile for tool-free fitment into the existing keyway on compatible drive shafts and hubs.
- Broad Compaction Equipment Compatibility — Fits RD25 tandem rollers, RS800H single drum rollers, DPU 2870/2950/2960/2970 reversible plates, and DPS3050/3060 vibratory plates.
- Drivetrain Integrity — A worn or missing Woodruff key causes shaft slippage, vibration, and loss of drive — replacing it promptly restores full power transmission to the compaction system.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component under part number 5000010386, ensuring material grade and geometry match original build specifications.
A Woodruff key is a small, semi-circular metal key that locks a rotating component — such as a pulley, sprocket, or drive hub — onto a shaft, preventing it from spinning independently. It fits into a matching curved slot (keyway) milled into both the shaft and the hub, creating a positive mechanical connection that transmits rotational torque. When a Woodruff key shears, wears, or falls out, the driven component loses its positive drive connection to the shaft, resulting in slippage, erratic vibration output, or complete loss of drive — making prompt replacement essential to restore normal compaction performance.
