The Bomag 05810505 Hydraulic Gear Motor is a genuine OEM component designed for Bomag BW 141 AD-4, BW 151 AD-4, BW 151 AC-4, and BW 154 AD-4 tandem rollers, including AM variants. Sourced directly from Bomag, this motor meets the exact specifications of the original unit it replaces. This hydraulic gear motor installs directly into the hydraulic drive circuit, restoring full drum propulsion and steering performance to your machine. If your tandem roller is showing signs of sluggish drive response, reduced drum speed, or loss of hydraulic pressure in the drive circuit, replacing this motor with part number 05810505 is the correct first step.
Key Features
- Genuine OEM Hydraulic Output Spec — manufactured to Bomag's original displacement and pressure ratings, ensuring proper flow and torque delivery in the drum drive circuit
- Direct-Swap Replacement — matches the original port configuration, shaft dimensions, and mounting pattern for a clean installation on covered tandem roller models
- Broad Tandem Roller Coverage — fits BW 141 AD-4, BW 141 AD-4 AM, BW 151 AD-4, BW 151 AD-4 AM, BW 151 AC-4, BW 151 AC-4 AM, BW 154 AD-4, and BW 154 AD-4 AM tandem rollers
- Drum Drive Reliability — a worn or failing hydraulic gear motor causes uneven drum speed, loss of tractive effort, and inconsistent mat density on asphalt passes; a properly functioning motor keeps compaction output consistent
- Verified Bomag Part Number — order with confidence knowing part number 05810505 is the correct OEM reference for these machines, eliminating guesswork during procurement
A hydraulic gear motor converts hydraulic flow from the machine's pump circuit into rotational mechanical force, driving the drum or propulsion system it is connected to. On Bomag tandem rollers, this component is central to maintaining consistent drum speed and smooth forward and reverse travel across the mat. When the motor wears internally — through gear erosion, seal degradation, or cavitation damage — it loses volumetric efficiency, resulting in reduced drive torque, heat buildup in the hydraulic system, and ultimately an inability to maintain the compaction passes required for a quality asphalt finish.
