The Bomag 05818263 Hydraulic Gear Motor is a genuine OEM component designed for Bomag BW-series tandem rollers spanning multiple generations and configurations. Sourced directly from Bomag, this motor meets the exact engineering specifications of the original unit it replaces. This hydraulic gear motor is confirmed to fit a wide range of tandem roller models including the BW 170 AD, BW 174 AD, BW 161 AD-5, BW 154 AD-5, BW 141 AD-5, BW 151 AD-5, and numerous AM, AC, AP, ACP, ADH, ADO, and generation-variant models across the BW 141, BW 151, BW 154, BW 161, and BW 174 series. When a hydraulic drive motor degrades or fails, it affects propulsion, drum rotation, or both — replacing it with the correct OEM part restores the machine to full operational capacity.
Key Features
- Genuine OEM Hydraulic Performance — matched to Bomag's original flow rate and pressure specifications for the BW-series tandem roller hydraulic drive system, ensuring correct torque output at the drum or drive circuit
- Direct-Fit Replacement — engineered to the same port configuration, shaft dimensions, and mounting interface as the original unit, allowing straightforward installation without modification
- Broad Tandem Roller Coverage — fits tandem rollers across the BW 141, BW 151, BW 154, BW 161, and BW 174 series, including AD, AC, AP, ACP, ADH, and ADO variants across multiple generations
- Protects Hydraulic System Integrity — a worn or underperforming gear motor can cause internal bypass, pressure loss, and accelerated wear on connected hydraulic components; an OEM-spec unit maintains proper system pressure and protects downstream components
- Consistent Drum Drive Reliability — correct hydraulic output keeps drum rotation and propulsion smooth and consistent, which is critical for achieving uniform compaction density on asphalt surfaces
A hydraulic gear motor converts hydraulic pressure from the machine's pump circuit into rotational mechanical output, driving the drum or propulsion system on the tandem roller. On Bomag tandem rollers, this component is central to both travel and vibratory drum functions — when it begins to wear, the machine may exhibit sluggish movement, uneven drum speed, or reduced compaction force. Replacing a failing unit with a genuine Bomag part number 05818263 restores the hydraulic circuit to its designed operating parameters and prevents further stress on the pump and valve system.
