The Wacker Neuson Upper Mass is a genuine OEM component designed for the DPU110rLec and DPU110rLem series reversible plate compactors, including the DPU110rLec970, DPU110rLec870, DPU110rLem970, and DPU110rLem870 models. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original, ensuring a direct fit without guesswork. It also covers the DPU110rLec970 US, DPU110rLem970 US, and DPU 80/110 KMAT configurations, making it the right choice across a wide range of DPU110r-series machines. When you need a structural mass component that performs the way the machine was built to perform, the OEM part is the straightforward answer.
Key Features
- OEM-Matched Mass Geometry — Manufactured to the original structural dimensions, so vibration transfer and compaction force are consistent with the machine's designed output.
- Direct-Fit Replacement — Engineered to mount to the same bolt pattern and mating surfaces as the original upper mass, keeping installation clean and straightforward.
- Broad DPU110r Series Coverage — Confirmed fitment across DPU110rLec970, DPU110rLec870, DPU110rLem970, DPU110rLem870, their US variants, and the DPU 80/110 KMAT.
- Sustained Compaction Performance — A correctly fitted upper mass maintains the balanced oscillation that drives effective soil and asphalt compaction; a worn or damaged mass disrupts that balance and reduces plate efficiency.
- Genuine Wacker Neuson Part — Carries full OEM traceability, so you know exactly what you are fitting and can trust the part to hold up under continuous reversible-plate operation.
The upper mass on a reversible plate compactor is one half of the two-mass vibration system that generates and controls compaction force. It sits above the lower mass and is connected through an exciter or spring isolation system, allowing the plate to deliver high-frequency impacts to the ground while absorbing shock away from the operator handles. When the upper mass is cracked, worn, or improperly fitted, the isolation between the working plate and the machine frame breaks down, leading to uneven compaction, excessive vibration transmitted to the operator, and accelerated wear on surrounding components. Replacing it with the correct OEM part restores the balanced dynamic the machine was designed around.
