The Wacker Neuson 5100018186 is a genuine OEM Eccentric Weight designed for the DPU110r series reversible vibratory plate compactors, including the DPU110rLec870, DPU110rLec970, DPU110rLem870, DPU110rLem970, and their US-market variants, as well as the DPU 80/110 KMAT configuration. As a direct OEM replacement, this part is manufactured to the same specification as the original component installed at the factory, ensuring consistent compaction output and proper vibratory balance. Verified fitment across the full DPU110r family makes the 5100018186 a dependable choice when restoring your machine to full operating condition. Keep this part number on hand for planned maintenance or emergency repair — accurate part identification is the fastest path back to productive compaction work.
Key Features
- OEM-Matched Mass and Balance — Manufactured to the original weight and geometry specification, ensuring the correct centrifugal force output and vibratory balance for the DPU110r compaction system.
- Drop-In Replacement — Mounts directly to the exciter shaft in place of the original component; no machining or custom fitting required on DPU110r series machines.
- Broad DPU110r Series Coverage — Confirmed fitment across DPU110rLec870, DPU110rLec970, DPU110rLem870, DPU110rLem970, US-market variants, and the DPU 80/110 KMAT plate.
- Restores Full Compaction Force — A worn or damaged eccentric weight reduces the amplitude of the plate's vibration, leading to uneven compaction and poor density results; replacing it brings output back to rated performance.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the same part number — 5100018186 — referenced in the OEM parts manual for these models.
The eccentric weight is the core component of a vibratory plate compactor's exciter assembly. It is mounted off-center on a rotating shaft driven by the engine; as it spins, the offset mass generates centrifugal force that translates into the rapid, high-frequency vibration the plate uses to compact soil, aggregate, or asphalt. On a reversible plate like the DPU110r series, eccentric weights are arranged so their phase relationship can be shifted to drive the plate forward or in reverse. If an eccentric weight becomes cracked, worn, or loses mass, the compaction force drops, vibration becomes uneven, and the machine may pull to one side or fail to achieve required compaction density — making timely replacement essential to maintaining productive, accurate compaction work.
