The Bomag 05818729 Steering Unit is a genuine OEM component designed for Bomag BW-series tandem rollers, including the BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 90 SC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SC-5, and BW 100 SCC-5. Sourced directly from Bomag, this steering unit matches the original specification installed at the factory, delivering an exact hydraulic and mechanical interface with no adaptation needed. Verified fitment across the full range of these tandem rollers means you can order with confidence, whether you're servicing a single machine or managing a fleet.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original hydraulic flow and pressure specifications, ensuring the steering response and feel operators expect from these tandem rollers
- Direct-Swap Replacement — engineered to the same port configuration and mounting dimensions as the original unit, allowing straightforward installation without reworking hydraulic lines or brackets
- Broad Tandem Roller Coverage — fits eight BW-series tandem roller models including the BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 90 SC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SC-5, and BW 100 SCC-5
- Steering Control Restored — a worn or failed steering unit causes heavy, inconsistent, or unresponsive articulation; replacing it with part number 05818729 restores precise directional control critical for accurate mat following on asphalt work
- Operator Safety Compliance — steering system integrity is a direct safety concern on ride-on compaction equipment; using a genuine OEM unit ensures the hydraulic steering circuit performs within Bomag's designed safety parameters
The steering unit is the hydraulic heart of the tandem roller's articulated steering system, translating input from the steering wheel into controlled movement of the machine's front and rear frames. It meters hydraulic fluid to the steering cylinder in proportion to operator input, giving smooth, predictable articulation across varying compaction conditions. When the steering unit wears internally or fails, the result can range from sluggish or jerky steering response to complete loss of directional control — making prompt replacement essential for both productivity and safe operation on the job.
