The Bomag 05551358 AC Hose Assembly WN3111 is a genuine OEM component designed for a wide range of Bomag cold milling machines, single drum rollers, tandem rollers, and pneumatic tyred rollers. Sourced directly from Bomag, this assembly delivers an exact match to the original specification — no guesswork on routing, end fittings, or hose length. Confirmed fitment spans models including the BM 2000/60, BM 2000/50, and BM 2000/60-2 cold milling machines, BW 177 and BW 179 series single drum rollers, BW 90 AD, BW 100 AD-5, BW 120 AD-5, BW 164 AD, and BW 174 AP-4 AM tandem rollers, the BW 12 R pneumatic tyred roller, and BW 100 SC-5 and BW 90 SC-5 tandem rollers, among others. When your air conditioning system shows signs of a failing or leaking hose, replacing it with part number 05551358 restores proper refrigerant flow and cabin climate control.
Key Features
- Genuine OEM Hose Construction — built to Bomag's original pressure rating and end-fitting specification, ensuring refrigerant containment and correct flex characteristics for the AC circuit
- Direct-Fit Replacement — hose length, routing profile, and connection ends match the original assembly, allowing installation without cutting, splicing, or adapting fittings
- Broad Confirmed Fitment — covers BM 2000-series cold milling machines, BW 177 and BW 179 single drum rollers across multiple generations, BW 100 and BW 120 AD-5 tandem rollers, and additional BW-series models; verify your model against part number 05551358 before ordering
- Restored Cabin Climate Performance — a compromised AC hose causes refrigerant loss, compressor strain, and loss of cab cooling; this assembly returns the system to full operating pressure and flow
- Refrigerant System Integrity — OEM-grade hose material resists oil, heat, and refrigerant permeation, helping maintain charge levels and protecting downstream AC components from contamination
The AC Hose Assembly WN3111 carries refrigerant between the major components of the machine's air conditioning system — compressor, condenser, and evaporator — under the pressure changes that occur during normal cooling operation. A hose that has cracked, chafed, or developed a leaking fitting will bleed refrigerant from the circuit, causing the system to underperform or shut down entirely and placing additional load on the compressor. Replacing a worn hose promptly with the correct OEM assembly keeps the AC circuit sealed and the operator cab comfortable during long shifts in hot conditions.
