The Bomag 05551307 AC Hose Assembly WN3111 is a genuine OEM hose assembly designed for a wide range of Bomag tandem rollers, single drum rollers, cold milling machines, and recycler/stabilizers. Sourced directly from Bomag, this assembly delivers an exact-match connection within the air conditioning system, ensuring proper refrigerant flow and system integrity. Compatible machines include the BW 75 ADL walk-behind/light roller, BW 90 AD, BW 141 AD-2, BW 151 AD-2, BW 161 AD-4, BW 202 AD-4, BW 174 AP-4, BW 138 AD-5, BW 135 AD-5, BW 124 DH-5, BW 124 PDH-5 single drum rollers, BM 1000/35, BM 1200/35, BM 1300/35 cold milling machines, and MPH 125, MPH 600, RS 650 recycler/stabilizers, among others. Replacing a degraded or leaking hose with a genuine OEM component restores correct AC system pressure and protects operator comfort on long shifts.
Key Features
- Genuine OEM Construction — Built to Bomag's original hose specification, with correct inner diameter, pressure rating, and end fittings to maintain AC system performance without improvised adaptation.
- Exact-Match Routing and Connections — Engineered to the WN3111 standard, this hose assembly aligns with the OEM routing path and connector ports, allowing direct installation in place of the original component.
- Broad Machine Coverage — Fits an extensive range of Bomag equipment including BW-series tandem rollers, BW 124 DH-5 and BW 124 PDH-5 single drum rollers, BM-series cold milling machines, and MPH/RS-series recycler/stabilizers.
- Maintains Refrigerant Integrity — A properly seated, undamaged hose assembly prevents refrigerant loss, keeping the AC circuit sealed and the cab cooling system fully functional in demanding operating conditions.
- Operator Safety and Comfort — A failed AC hose can rapidly depressurize the refrigerant circuit; replacing it with a genuine Bomag part restores safe, manufacturer-intended system operation and protects operator wellbeing.
- Verified Part Number Fit — Order with confidence using part number 05551307, confirmed against Bomag's OEM catalog for the listed models.
The AC Hose Assembly WN3111 is a pressurized refrigerant line that connects key components within the machine's air conditioning circuit, carrying refrigerant between the compressor, condenser, and evaporator to enable cab cooling. When this hose degrades — through cracking, abrasion, or fitting failure — the system loses refrigerant pressure, causing the AC to underperform or shut down entirely. Fitting a genuine OEM replacement ensures the hose can withstand the operating pressures and temperatures of the machine's AC system, restoring full climate control to the operator cab.
