Wacker Neuson 5000156868 Key Set

The Wacker Neuson Key Set is a genuine OEM component designed for the RD25 and RD15 hydrostatic double drum vibratory tandem rollers. As a factory-sourced part, this Key Set is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation on compatible machines. This is the exact replacement to specify when servicing the drivetrain or powertrain shaft connections on these tandem roller models.

Key Features

• Genuine OEM Fit: — Sourced directly from Wacker Neuson, this Key Set meets the precise dimensional tolerancing required for shaft-to-hub engagement on RD-series tandem rollers — no guesswork on sizing or profile.
• Direct Replacement: — Installs in the original keyway slot without modification, restoring positive torque transfer between shaft and mating component exactly as designed.
• RD25 and RD15 Compatibility: — Confirmed fitment for the RD25 and RD15 hydrostatic double drum vibratory tandem rollers, used in asphalt and soil compaction applications.
• Torque Transmission Integrity: — A worn, sheared, or missing key allows shaft slippage, causing loss of drive to the drum or hydraulic component — replacing it promptly restores full power delivery and prevents secondary damage.
• Verified Part Number: — Part number 5000156868 cross-references directly to the RD25 and RD15 machine families, so you can order with confidence that this is the correct key for your machine.

A key set provides the mechanical connection between a rotating shaft and the hub or gear mounted on it, transmitting torque without slippage by sitting in a precision-cut keyway machined into both components. On a hydrostatic tandem roller like the RD25 or RD15, these keys are critical to maintaining positive drive engagement across the drum and hydraulic drive circuit. When a key shears or wears, the shaft spins freely inside the mating component, resulting in loss of drum drive or control response — making prompt replacement essential to restoring full machine operation.
