The Wacker Neuson 5100018187 is a genuine OEM Eccentric Weight designed for the DPU110r series reversible vibratory plate compactors. As a direct factory replacement, this part is manufactured to the same specifications as the original component, ensuring consistent compaction force output across the full DPU110r lineup. Confirmed fitment covers the DPU110rLec870, DPU110rLec970, DPU110rLem870, DPU110rLem970, their US-market variants, and the DPU 80/110 KMAT vibration plate configuration. When you need a dependable, like-for-like replacement to restore your machine's compaction performance, part 5100018187 is the correct choice.
Key Features
- Genuine OEM Mass and Balance Spec — Manufactured to the exact weight and geometry of the original eccentric, preserving the designed centrifugal force and compaction amplitude of the DPU110r.
- Drop-In Shaft Compatibility — Engineered to mount directly onto the exciter shaft without modification, maintaining the correct offset and rotational balance from the first run.
- Broad DPU110r Series Coverage — Fits DPU110rLec870, DPU110rLec970, DPU110rLem870, DPU110rLem970 (including US-market variants), and DPU 80/110 KMAT machines.
- Restores Full Compaction Force — A worn or damaged eccentric weight reduces centrifugal output, leading to uneven compaction passes; replacing with 5100018187 brings the machine back to rated performance.
- Balanced for Safe High-Speed Operation — Eccentric weights operate at high rotational speeds inside the exciter housing; an out-of-spec replacement introduces vibration imbalance that can stress bearings and housings, making correct mass critical.
The eccentric weight is the core driver of vibration in a vibratory plate compactor. Mounted inside the exciter assembly and spun at high speed by the engine-driven shaft, its offset mass generates the centrifugal force that translates into downward compaction energy through the base plate. On a reversible plate like the DPU110r series, paired eccentric weights are phased to control the direction of travel as well as compaction amplitude. When an eccentric weight is worn, cracked, or loses mass, the machine produces less compaction force, exhibits erratic directional behavior, and places additional stress on the exciter bearings — ultimately reducing pass effectiveness on soil and aggregate applications.
