The Bomag 05554853 AC Hose Assembly WN3111 is a genuine OEM air conditioning hose assembly designed for Bomag cold milling machines and tandem rollers, including the BM 2000/60, BM 2000/50, BM 2000/60-2, BW 135 AD, BW 138 AD, BW 138 AC, BW 138-AD, BW 100 AD-4, BW 120 AD-4, BW 125 AD-4, BW 120 AD 4, BW 100 AD-5, BW 120 AC-5, BW 120 AD-5, BW 100 AC-5, BW 120 SL-5, and BW 100 SL-5. As a genuine Bomag OEM component, this hose assembly is manufactured to the exact specifications of the original, ensuring a direct, trouble-free installation with no guesswork on routing or connection sizing. Sourced directly through authorized Bomag supply channels, part number 05554853 is the correct replacement when the original hose shows signs of wear, cracking, or refrigerant loss.
Key Features
- Genuine OEM Construction — Built to Bomag's exact pressure ratings and hose material specifications, ensuring the AC circuit maintains correct refrigerant flow and system integrity throughout the operator cab.
- Direct-Fit Replacement — Engineered to match the original routing path, end fittings, and connection diameters so this assembly seats correctly without modification to existing brackets or ports.
- Broad Fitment Coverage — Confirmed fit across Bomag BM 2000-series cold milling machines and BW 100 through BW 138 tandem rollers, including AD, AC, and SL variants across the -4 and -5 generations.
- Cab Comfort Restored — A compromised AC hose causes refrigerant loss and cab cooling failure; replacing it with this assembly restores full air conditioning output and keeps operators comfortable during long paving and milling shifts.
- Refrigerant System Safety — A cracked or failed hose can allow refrigerant to escape, creating both environmental and health hazards; using the correct OEM hose assembly maintains a sealed, compliant AC circuit.
The AC Hose Assembly WN3111 is a pressurized refrigerant line within the machine's air conditioning system, responsible for carrying refrigerant between major AC components such as the compressor, condenser, and evaporator. A correctly functioning hose maintains a sealed, leak-free circuit so the system can sustain proper pressure and deliver consistent cab cooling. When this hose deteriorates — through cracking, abrasion, or fitting failure — refrigerant escapes, AC performance drops rapidly, and continued operation can damage the compressor and other system components.
