The Bomag 05766807 Steering Unit is a genuine OEM component designed for a broad range of Bomag BW-series single drum rollers, tandem rollers, and BM-series cold milling machines. As a factory-sourced part, this steering unit matches the original specifications of the unit it replaces, ensuring correct hydraulic response and precise directional control from the moment it is installed. Compatible models include the BW 177 DH-4, BW 213 DH-4, BW 226 DH-4, BW 226 DH-4i, BW 332, BW 141 AD-5, BW 151 AD-5, BW 161 AD-5, BW 190 AD-5, BW 206 AD-5 AM, BW 174 AP-4, BW 154 AP-4, BW 154 ACP-4, and BM 1000/35, BM 1200/35, and BM 1300/35, among others. Sourcing a direct OEM replacement like part number 05766807 keeps your machine operating with the steering response and control accuracy these rollers and milling machines demand.
Key Features
- OEM Hydraulic Steering Precision — Manufactured to Bomag's original pressure and flow specifications, this steering unit delivers the metering accuracy required for consistent, predictable directional control on compaction and milling passes.
- Direct-Fit Replacement — the part matches the hydraulic port configuration and mounting interface of the original unit, allowing installation without line modification or adapter fittings.
- Broad BW and BM Series Coverage — Fits BW-series single drum rollers including the BW 177 DH-4, BW 213 DH-4, and BW 226 DH-4, tandem rollers including the BW 154 AP-4, BW 174 AP-4, BW 190 AD-5, and BW 141 AD-5, and cold milling machines including the BM 1000/35, BM 1200/35, and BM 1300/35.
- Restored Steering Response — A worn or leaking steering unit causes sluggish wheel response, drift, and loss of fine control — replacing it with this OEM unit restores crisp, load-proportional steering feel and operator confidence.
- Operator Safety — Steering system integrity is critical on heavy rollers and milling machines operating on grades and in traffic. An OEM-spec unit maintains the hydraulic control characteristics the machine's safety systems depend on.
The steering unit is a hydrostatic orbitrol-type valve that converts the operator's steering wheel input into controlled hydraulic flow to the machine's steering cylinders. It meters oil precisely in proportion to wheel rotation, allowing smooth, effort-free directional changes even under load. When this unit wears internally or develops leaks, the result is erratic steering, excessive play, or a complete loss of hydraulic assist — any of which can compromise both productivity and safe machine operation.
