The Bomag 05902565 Steering Unit is a genuine OEM replacement built for Bomag tandem rollers, including the BW 135 AD, BW 138 AD, BW 138 AC, BW 138-AD, BW 125 AD-4, BW 125 AC-4, BW 131 ACW-3, BW 131 AD-3, BW 115 AC-5, BW 131 AD-5, and BW 131 ACW-5. Sourced directly from Bomag, this steering unit matches the original specification so it installs into your machine without adaptation. When your tandem roller's steering response is sluggish, erratic, or unresponsive, replacing this unit with a verified OEM component restores the precise hydraulic steering control these machines demand on asphalt work.
Key Features
- Genuine OEM Hydraulic Steering Precision — manufactured to Bomag's exact tolerancing for metered hydraulic flow and steering response, so the unit delivers consistent, proportional control from the first use
- Direct-Fit Replacement — matches the original port configuration and mounting interface of the 05902565 application, dropping into the hydraulic steering circuit without rework or custom fittings
- Broad Tandem Roller Coverage — fits eleven Bomag tandem roller variants including the BW 135 AD, BW 138 AD, BW 125 AD-4, BW 131 AD-5, BW 131 ACW-5, and BW 115 AC-5, among others in the BW tandem series
- Restored Steering Control — a worn or failed steering unit causes wheel wander, heavy steering effort, and imprecise tracking on the mat; this replacement brings articulation response back to specification so your crew maintains straight, consistent passes
- Operator Safety Confidence — on a tandem roller working on live road surfaces, predictable and responsive steering is a direct safety requirement; an OEM-grade unit ensures the steering circuit performs as the machine was designed
The steering unit is the hydraulic-mechanical heart of the tandem roller's articulated steering system. It converts the operator's steering wheel input into precisely metered hydraulic pressure that moves the articulation joint between the front and rear frames, directing the machine through turns and keeping it tracking straight on the mat. When the steering unit wears or fails internally, fluid bypasses its metering valves and steering becomes heavy, delayed, or unpredictable — making accurate compaction passes difficult and creating a genuine safety concern on public roadways. Replacing a degraded unit promptly keeps the roller tracking accurately and the operator in full control.
