The Wacker Neuson Upper Mass is a genuine OEM component designed for VP1135A vibratory plate compactors. As a factory-sourced part, it is manufactured to the same specifications as the original, ensuring a correct, like-for-like replacement every time. This part is confirmed to fit the VP1135A series, including both standard and US configurations. When you need the right part the first time, sourcing genuine OEM keeps your compactor running the way it was built to run.
Key Features
- Genuine OEM Mass Integrity — Manufactured by Wacker Neuson to original weight and balance tolerances, preserving the compaction dynamics the VP1135A was engineered to deliver.
- Direct Drop-In Replacement — Matches the original upper mass mounting configuration exactly, fitting into the VP1135A assembly without rework or modification to surrounding components.
- Confirmed VP1135A Fitment — Verified for VP1135A and VP1135A US model variants, covering both standard and US-market compactor configurations.
- Compaction Force Preserved — A correctly weighted upper mass maintains proper force transmission through the plate, ensuring consistent soil and asphalt compaction. A worn or damaged upper mass disrupts the vibration balance and compromises compaction results.
- Sourced Factory-Direct — Carries the Wacker Neuson genuine OEM designation, meaning this part left the same supply chain as your original equipment — not an approximation of it.
The upper mass is a core structural component of a vibratory plate compactor's exciter system. It works in conjunction with the lower mass and eccentric weights to generate the oscillating force that drives compaction into the ground. When the upper mass is cracked, worn, or improperly weighted, the vibration balance of the entire compactor is thrown off, leading to uneven compaction, increased stress on surrounding components, and reduced output from the machine. Replacing it with a genuine OEM part restores the designed vibration frequency and amplitude, getting the plate back to full compaction performance.
