The Bomag 05813303 Gear Motor is a genuine OEM component designed for Bomag tandem rollers, including the BW 161 AD-5, BW 161 AC-5, BW 161 ADO-5, BW 190 AD-5, BW 190 ADO-5, BW 191 AD-5, BW 191 AD-5 AM, BW 191 ADO-5, BW 202 AD-5, BW 202 ADO-5, BW 206 AD-5, and BW 206 AD-5 AM. Sourced directly from Bomag, this gear motor meets the same specifications as the unit originally fitted at the factory, so you can install it with confidence. It is the correct replacement for operators and service technicians maintaining fifth-generation Bomag tandem rollers across the BW 161, BW 190, BW 191, BW 202, and BW 206 series.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact displacement and pressure tolerances, ensuring consistent flow and torque output specific to this gear motor application.
- Direct-Fit Replacement — matches the original port configuration, shaft dimensions, and mounting footprint for a straightforward swap on compatible tandem rollers.
- Broad Fifth-Generation Tandem Roller Coverage — confirmed fitment across the BW 161, BW 190, BW 191, BW 202, and BW 206 tandem roller families, including AD-5, AC-5, ADO-5, and AM variants.
- Sustained Drive Performance — a properly functioning gear motor maintains steady hydraulic flow to the drum drive circuit; a worn or failing unit causes sluggish response, uneven drum speed, and loss of compaction control.
- Hydraulic System Integrity — OEM sealing and internal clearances prevent internal bypass leakage that can overheat hydraulic fluid and accelerate wear throughout the drive circuit.
A gear motor converts hydraulic flow from the machine's hydraulic system into rotational mechanical output, driving the drum or auxiliary systems that depend on it. In a tandem roller, the gear motor plays a critical role in delivering consistent power to keep the drums turning at the correct speed for smooth, even asphalt compaction passes. When a gear motor begins to fail — through worn gear sets, seal deterioration, or internal bypass — the machine loses drive efficiency, drum speed becomes erratic, and the hydraulic system works harder than intended, risking broader drivetrain damage.
