The Bomag 05902279 Steering Unit is a genuine OEM component designed for BW 177 and BW 179 series single drum rollers. Sourced directly from Bomag, this steering unit delivers an exact match to the original specification, ensuring seamless installation and correct hydraulic integration on covered machines. This part is confirmed to fit a wide range of BW 177 and BW 179 variants, including the BW 177 D-3 USA, BW 177 DH-4, BW 177 PDH-50, BW 179 DH-4, BW 179 PDH-4, and BW 179 DHC-4, among others. When the original steering unit begins to fail, replacing it promptly with a genuine Bomag part keeps your roller operating with the directional responsiveness these machines demand on compaction sites.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original design tolerances, ensuring correct hydraulic pressure and steering response specific to BW 177 and BW 179 single drum rollers
- Direct-Fit Replacement — matches the original mounting configuration and hydraulic port layout, allowing straightforward installation without adaptation
- Broad BW 177 and BW 179 Coverage — fits multiple variants across the BW 177 and BW 179 single drum roller families, including D, DH, PDH, DHC, and PDHC configurations spanning -3 USA through -50 generation machines
- Restored Directional Control — a correctly functioning steering unit gives the operator full, responsive command of the roller's travel direction, which is critical for accurate compaction passes and tight maneuvering on grade
- Safety-Critical Component — the steering system is a primary operator safety control; using a genuine Bomag replacement maintains the hydraulic integrity and steering force ratings the machine was designed around
The steering unit is the hydraulic heart of the roller's directional control system, translating operator input at the steering wheel into controlled hydraulic pressure that articulates the machine. On single drum rollers like the BW 177 and BW 179, precise and predictable steering is essential for laying straight compaction passes and maintaining safe machine control on sloped or confined worksites. When the steering unit degrades or fails, operators may notice sluggish response, steering drift, or complete loss of directional control — all of which create both productivity and safety risks that require immediate attention.
