The Bomag 05554403 AC Hose Assembly WN3111 is a genuine OEM component designed for Bomag single drum rollers, tandem rollers, and the BC 772 RS refuse/landfill compactor. Sourced directly from Bomag, this assembly matches the original routing, fittings, and pressure ratings of the factory air conditioning circuit. Confirmed fitment covers the BW 138 AC-5, BW 138 AD-5, BW 135 AD-5, BW 145 DH-5, BW 145 PDH-5, BW 177 DH-5, BW 177 PDH-5, BW 177BVC-5, BW 177-5, BW 177 PDH-5 PL, and BW 177 DH-5 PL, as well as the BC 772 RS.
Key Features
- Genuine OEM Pressure Rating — manufactured to Bomag's exact hydraulic and refrigerant pressure specifications for the AC circuit, so the assembly handles operating demands without seeping or ballooning
- Direct-Fit Routing and Connections — hose length, bend geometry, and end fittings match the original layout, allowing the assembly to seat and torque correctly without rerouting or adapter fittings
- Broad Model Coverage — fits BW 135, BW 138, BW 145, and BW 177 series tandem and single drum rollers, plus the BC 772 RS refuse/landfill compactor, all from a single part number 05554403
- Cabin Comfort Restored — a failed or cracked AC hose causes refrigerant loss and complete cabin cooling failure; this assembly restores full air conditioning output for operator comfort in demanding conditions
- Refrigerant System Integrity — correct hose material and O-ring seating surfaces prevent refrigerant leaks that can damage compressor components and trigger system shutdown
The AC Hose Assembly WN3111 is a pressurized refrigerant line within the machine's cab air conditioning system, connecting key components such as the compressor, condenser, or evaporator to maintain the sealed circuit that circulates refrigerant. When the hose cracks, chafes, or its end fittings corrode, refrigerant escapes, the system loses pressure, and the air conditioning stops cooling the operator cab entirely. Replacing a damaged hose promptly with an exact-fit OEM assembly protects the compressor from running dry and restores the climate-controlled environment operators depend on during long shifts in the heat.
