The Bomag 05810500 Hydraulic Gear Motor is a genuine OEM component designed for Bomag BW 161 AD-4, BW 161 ADH-4, BW 161 AC-4, BW 190 AD-4, BW 190 AD-4 AM, BW 202 AD-4, BW 203 AD-4, and BW 203 AD-4 AM tandem rollers. Sourced directly from Bomag, this hydraulic gear motor matches the original unit in every critical dimension and specification, ensuring a drop-in replacement with no guesswork. As a genuine OEM part, it is built to the same standards as the component that left the factory, giving you full confidence in fit and long-term function. Confirm part number 05810500 against your machine's service documentation before ordering to ensure correct application.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to exact displacement and pressure tolerances required by Bomag tandem roller hydraulic drive systems, delivering consistent torque output under load
- Direct-Fit Replacement — matches the original port configuration, shaft dimensions, and mounting bolt pattern of the factory-installed unit for a straightforward swap
- Broad Tandem Roller Coverage — confirmed fitment across the BW 161 AD-4, BW 161 ADH-4, BW 161 AC-4, BW 161 ADH-4 CHINA, BW 190 AD-4, BW 190 AD-4 AM, BW 202 AD-4, BW 203 AD-4, and BW 203 AD-4 AM tandem rollers
- Restored Drive Performance — a worn or failing hydraulic gear motor causes loss of drum drive force and uneven compaction; replacing it with part number 05810500 restores full propulsion and compaction output
- Hydraulic System Integrity — proper internal clearances prevent internal bypass leakage that can overheat hydraulic fluid and accelerate wear across connected system components
A hydraulic gear motor converts pressurized hydraulic fluid into rotational mechanical force, driving the drum or propulsion system on your tandem roller. On Bomag tandem rollers, this motor is central to smooth, controllable drum rotation and consistent forward and reverse travel across asphalt surfaces. When the motor wears internally or fails, operators typically notice sluggish drum response, loss of propulsion power, or audible noise from the hydraulic circuit — all of which compromise compaction quality and machine control.
