The Bomag 51010801 Eccentric Weight is a genuine OEM component designed for the BW 142 D-2 single drum roller. Sourced directly from Bomag, this eccentric weight matches the original part in mass, geometry, and balance to restore the drum's vibration output to spec. It installs as a direct replacement in the BW 142 D-2 vibration system, requiring no improvised fitment. Buyers can order with confidence knowing part number 51010801 is the exact Bomag-approved component for this machine.
Key Features
- OEM Mass and Balance Specification — manufactured to Bomag's exact weight and geometry tolerances, ensuring the drum generates the correct centrifugal force for consistent compaction output
- Direct-Fit Replacement — engineered to swap directly into the vibration assembly of the BW 142 D-2, matching all mounting dimensions and rotational clearances of the original
- Confirmed Fitment — part number 51010801 is verified for the BW 142 D-2 single drum roller
- Restored Compaction Performance — a correctly weighted eccentric restores full drum amplitude and frequency, keeping compaction depth and density consistent across every pass
- Genuine Bomag OEM Quality — produced under Bomag's manufacturing standards, ensuring the same material grade and dimensional accuracy as the part originally installed at the factory
The eccentric weight is a core element of a vibratory drum roller's compaction system. Mounted inside the drum shell and driven by the vibration motor, it spins at high speed to generate centrifugal force, which causes the drum to vibrate and drive compaction energy into the soil or base material below. When an eccentric weight cracks, loses mass, or becomes unbalanced, the drum's amplitude drops, compaction energy becomes uneven, and the machine may produce visible vibration irregularities or fail to reach target density. Replacing a worn or damaged eccentric weight with a correctly specified OEM part is the most direct way to bring the BW 142 D-2 back to full compaction performance.
