The Bomag 05550171 AC Hose Assembly WN3111 is a genuine OEM component designed for Bomag BM 2000/60 and BM 2000/60-2 cold milling machines, as well as BC 670 RB, BC 570 RB, BC 972 RB-4, and BC 1172 RB-4 refuse and landfill compactors. Sourced directly from Bomag, this assembly matches the original routing, fittings, and pressure ratings of the factory-installed hose. It installs directly in place of the worn or damaged unit, restoring full air conditioning circuit integrity with no guesswork on compatibility. Confirm your model against the fitment list before ordering to ensure a correct application match.
Key Features
- OEM-Grade Hose Construction — Built to Bomag's original pressure and temperature specifications for the A/C circuit, ensuring the hose holds up under the demanding thermal cycles of heavy-duty milling and compaction work.
- Exact-Fit Routing and Connections — End fittings, hose length, and bend geometry match the original assembly, allowing this component to seat correctly within the existing A/C plumbing layout.
- Broad Model Coverage — Fits BM 2000/60 and BM 2000/60-2 cold milling machines, plus BC 570 RB, BC 670 RB, BC 972 RB-4, and BC 1172 RB-4 refuse and landfill compactors.
- Restores Cab Climate Control — A failed or leaking A/C hose causes refrigerant loss and complete loss of cab cooling — replacing this assembly returns the operator environment to a safe, controlled temperature on long production runs.
- Genuine Bomag Part — Supplied as an authentic Bomag OEM part under part number 05550171, eliminating the risk of dimensional mismatches or premature failure from non-original components.
The AC Hose Assembly WN3111 is a pressurized flexible line within the machine's air conditioning system, responsible for carrying refrigerant between major A/C components such as the compressor, condenser, and evaporator. It must maintain a sealed, leak-free connection under fluctuating pressures and temperatures generated during normal machine operation. When this hose degrades, cracks, or its fittings loosen, refrigerant escapes, the A/C system loses cooling capacity, and continued operation can damage the compressor — making prompt replacement critical to both operator comfort and system longevity.
