The Bomag 05902136 Steering Unit is a genuine OEM component designed for BW 100, BW 115, BW 120, and BW 125 series tandem rollers. Sourced directly from Bomag, this steering unit delivers an exact OEM-spec replacement with no guesswork on compatibility. It is confirmed to fit AC-3, AD-3, AC-4, and AD-4 variants across the BW 100, BW 115, BW 120, and BW 125 tandem roller lines, covering a wide range of machines in service today. When your steering system needs attention, replacing it with part number 05902136 ensures the machine returns to correct, responsive operation.
Key Features
- OEM Hydraulic Steering Precision — manufactured to Bomag's original specifications, delivering the correct flow rate, pressure response, and steering feel expected from the factory unit
- Direct-Swap Installation — matches the original mounting configuration and port layout of the steering circuit, allowing straightforward removal and reinstallation without custom adapters
- Broad Tandem Roller Coverage — fits BW 100 AC-3, BW 100 AD-3, BW 100 AC-4, BW 100 AD-4, BW 115 AC-3, BW 115 AD-3, BW 120 AC-3, BW 120 AD-3, BW 120 AC-4, BW 120 AD-4, BW 125 AD-4, and related variants
- Restored Steering Control — a failed or sluggish steering unit compromises machine maneuverability on the mat; this part restores full, predictable directional response so the roller tracks accurately
- Operator Safety Confidence — the steering unit is a primary control component; using an authentic Bomag replacement ensures the hydraulic steering circuit performs within the design tolerances required for safe machine operation
The steering unit is the hydraulic control heart of the tandem roller's articulated steering system. It translates input from the steering wheel into precise hydraulic pressure commands that direct the machine left or right, giving the operator accurate, proportional control over the roller's path. When this component wears or fails, symptoms range from sluggish or uneven steering response to complete loss of directional control — conditions that reduce paving accuracy and create serious safety concerns on the worksite. Replacing a worn unit with a correct OEM part restores the hydraulic circuit to its intended operating parameters and brings the machine back to full working capability.
