The Wacker Neuson Unbalance Shaft is a genuine OEM component designed for RC110 and RC110P series ride-on compactors, including US ROPS and US CAB configurations. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a correct fit within the compaction drum assembly. It is compatible across the full RC110 and RC110P lineup, covering both standard and enclosed cab variants. When you order the, you are getting the exact part Wacker Neuson specifies for these machines — no guesswork, no adapting.
Key Features
- Genuine OEM Mass Tolerance: — Manufactured to Wacker Neuson's original eccentric mass specification, so vibration output and compaction force remain consistent with the machine's designed performance envelope.
- Drop-In Drum Assembly Fit: — Shaft dimensions and bearing journals match the original exactly, allowing direct installation into the drum housing without reworking mounting points.
- Broad RC110 Series Coverage: — Fits RC110 and RC110P models across standard, US ROPS, and US CAB configurations, making this a single part solution for fleet operators running mixed RC110 variants.
- Sustained Compaction Output: — A correctly balanced unbalance shaft maintains the drum's rated centrifugal force, delivering consistent compaction depth and pass efficiency on every lift.
- Sourced from Wacker Neuson: — Supplied as a genuine OEM part, backed by Wacker Neuson's parts chain for material grade and dimensional accuracy.
The unbalance shaft is the rotating eccentric component inside a compactor's drum that generates the vibration force used to compact soil, asphalt, or granular material. As the shaft spins, its off-center mass creates centrifugal force that drives the drum into rapid oscillation, which is what pushes compaction energy down into the material layer. When the unbalance shaft wears, becomes damaged, or develops bearing play, vibration amplitude drops, compaction quality suffers, and the operator may notice increased drum noise or irregular surface finish — all signs the shaft needs immediate attention.
