The Wacker Neuson Upper Mass is a genuine OEM component designed for the DPU 4045H and DPU 5045H series reversible vibratory plate compactors. As a direct factory replacement, this part meets the original engineering specifications for these diesel-powered reversible plates. Fitment covers multiple machine configurations across both the DPU 4045H and DPU 5045H model lines, making part number the correct choice for operators and service technicians working on this equipment. Order with confidence knowing this is a sourced-from-manufacturer part, not a substitute.
Key Features
- Genuine OEM Construction: — Manufactured to the exact mass and dimensional tolerances required for correct vibratory performance in DPU-series reversible plate compactors.
- Direct Bolt-On Replacement: — Engineered to locate and mount exactly as the original, using existing hardware and mounting points on the DPU 4045H and DPU 5045H frames.
- Broad DPU Series Fitment: — Confirmed compatibility across multiple DPU 4045H and DPU 5045H machine configurations, including diesel variants in the 50 kN, 45 cm/18 in class.
- Restores Correct Vibration Isolation: — The upper mass is a core structural element of the isolation system; a worn or damaged unit compromises operator comfort and compaction consistency.
- Backed by Wacker Neuson OEM Sourcing: — Supplied as a genuine factory part, ensuring material grade and geometry match what was originally installed on the machine.
The upper mass is one of two primary structural assemblies in a vibratory plate compactor's isolation system — the other being the lower mass that houses the exciter. The upper mass sits above the anti-vibration mounts and carries the engine, fuel system, and operator handles, isolating them from the high-frequency vibration generated below. This separation is what makes the machine both controllable and comfortable to operate over extended periods. When the upper mass is cracked, deformed, or its mounting interfaces are damaged, the isolation system cannot function correctly, leading to excessive vibration transmitted to the operator and potentially misaligned engine or handle components.
