The Wacker Neuson Unbalance is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100c series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact design and material specifications required for proper vibratory system operation. It covers a broad range of RD18 variants — including US and SE configurations as well as the updated.3 series models — making it the correct choice across the full RD18 product family. When your compaction equipment needs this component replaced, specifying the genuine OEM part ensures the vibratory system performs as it was engineered to.
Key Features
- Genuine OEM Mass Specification: — Manufactured to the precise eccentric mass and balance tolerances required to generate correct vibratory force — critical for consistent compaction output.
- Direct Drop-In Replacement: — Designed to install into the drum assembly exactly as the original, with no reworking of mounting points or hardware.
- Broad RD18 Series Coverage: — Fits RD18-80, RD18-100, and RD18-100c models including US, SE, and .3 series variants across multiple production configurations.
- Restores Full Compaction Performance: — A worn or damaged unbalance weight disrupts vibration amplitude and frequency, leading to uneven compaction; replacing it brings drum vibration back to rated output.
- Verified Part Number: — Part number 5100068719 is confirmed against Wacker Neuson's OEM parts documentation, so you can order with confidence that this is the correct component for your machine.
The unbalance — also referred to as an eccentric weight or unbalance shaft assembly — is the component inside a vibratory roller's drum that generates the oscillating compaction force. As the drum spins, the offset mass creates centrifugal force that causes the drum to vibrate against the ground, driving compaction of soil, asphalt, or base material. When the unbalance weight is worn, damaged, or incorrectly specified, vibration amplitude drops or becomes irregular, resulting in poor compaction density and inconsistent surface results. Replacing a failed unbalance with the correct OEM part restores the drum's rated vibration characteristics and ensures the machine compacts to specification.
