The Bomag 05802505 Vibration Motor is a genuine OEM component designed for Bomag tandem rollers across a wide range of BW-series models, including the BW 161 AD-2, BW 170 AD, BW 202 AD-2, BW 174 AD-2, BW 190 AD-4, BW 203 AD-4, BW 205 AD 4, and many additional variants. Sourced directly through Bomag's OEM supply chain, this vibration motor carries the same specifications as the unit installed at the factory, ensuring an exact match for the hydraulic and mechanical interfaces on your machine. Confirmed fitment spans the full lineup listed above, so you can order with confidence knowing this is the correct part for your roller.
Key Features
- Genuine OEM Hydraulic Motor Specification — matched to Bomag's original flow rate, displacement, and pressure ratings for tandem roller vibration circuits, not a generic substitute
- Direct Bolt-On Replacement — engineered to match the original mounting flange, port configuration, and shaft dimensions so this motor seats and connects without rework
- Broad BW-Series Tandem Roller Coverage — verified for BW 141, BW 151, BW 154, BW 161, BW 170, BW 174, BW 190, BW 202, BW 203, and BW 205 tandem roller variants, including AM, AC, AD, AHD, ADH, ADO, AP, ACP, and EU-Flex configurations
- Restored Compaction Output — a correctly functioning vibration motor drives the eccentric weights at the designed frequency and amplitude, delivering consistent compaction force across the drum; a worn or failed motor causes uneven or absent vibration, resulting in under-compacted asphalt
- Hydraulic System Integrity — OEM-spec internal seals and porting prevent pressure loss and cross-contamination within the vibration circuit, protecting downstream hydraulic components from wear caused by an underperforming motor
The vibration motor is a hydraulic motor that drives the eccentric shaft inside the roller drum, generating the high-frequency oscillation that gives a tandem roller its compaction capability. Without a functioning vibration motor, the drum rolls over the surface without delivering the vibratory force needed to densify asphalt or soil, leaving compaction targets unmet. When this motor degrades — through seal failure, internal wear, or cavitation damage — operators typically notice reduced drum vibration, increased hydraulic system heat, or complete loss of vibratory function, all of which directly affect pass counts and finished mat quality.
