The Bomag 05802016 Radial Piston Motor is a genuine OEM hydraulic drive component designed for BW 190 AD-4 AM and BW 203 AD-4 AM tandem rollers. Sourced directly from Bomag, this radial piston motor matches the original unit in form, fit, and hydraulic specification — no adaptation needed to restore proper drum drive performance. This part is the correct replacement for all covered variants, including the BW 203 AD-4 AM EU-Flex tandem roller.
Key Features
- Genuine OEM Hydraulic Specification — manufactured to Bomag's exact displacement, pressure rating, and porting configuration, ensuring the motor delivers the correct torque output for drum propulsion on these tandem rollers
- Direct-Fit Replacement — mounts to the existing hydraulic circuit and drum drive interface on covered machines, allowing a straightforward swap without custom fittings or machining
- Confirmed Tandem Roller Fitment — compatible with the BW 190 AD-4 AM, BW 203 AD-4 AM, and BW 203 AD-4 AM EU-Flex tandem rollers
- Sustained Drum Drive Performance — a properly functioning radial piston motor maintains consistent drum rotation speed and traction across variable compaction loads; a worn or failed motor causes loss of drive, uneven drum speed, or complete propulsion failure
- Verified Part Number Integrity — order with confidence using Bomag part number 05802016, the OEM-designated reference for this application, eliminating guesswork in parts sourcing
A radial piston motor converts hydraulic flow from the machine's drive circuit into rotational force at the drum, providing the propulsion needed to move and compact material across the work surface. On tandem rollers like the BW 190 AD-4 AM and BW 203 AD-4 AM, the motor is a core element of the hydrostatic drive system — its output directly determines drum speed, tractive effort, and the machine's ability to maintain steady forward and reverse passes. When this motor wears or fails, operators will notice sluggish drum response, loss of traction, or an inability to maintain consistent travel speed, all of which compromise compaction quality and throughput.
