The Bomag 05551712 AC Hose Assembly WN3111 is a genuine OEM replacement built for Bomag BW 211, BW 213, BW 214, BW 215, BW 216, and C850D single drum rollers. Sourced directly from Bomag, this assembly matches the original routing, fittings, and refrigerant-rated construction of the factory hose it replaces. It fits a wide range of -3, -4, -4i, -40, -50, and DE-40 generation variants, including padfoot and high-compaction configurations such as the BW 213 PDH-3, BW 211 PD-4, BW 216 PD-4i, and BW 213 PDHC-4. When your cab air conditioning system develops a leak or the hose shows signs of cracking or wear, this part restores proper refrigerant flow and system pressure without the guesswork of sourcing an off-spec replacement.
Key Features
- Genuine OEM Refrigerant-Rated Construction — manufactured to Bomag's original pressure and temperature specifications for air conditioning circuits, so the hose performs correctly under the thermal cycling demands of heavy compaction work
- Direct-Fit Routing and Connections — hose length, end fittings, and bend geometry match the OEM layout exactly, allowing installation against the factory brackets and connection points on covered BW-series single drum rollers
- Broad Single Drum Roller Coverage — confirmed for BW 211, BW 212, BW 213, BW 214, BW 215, BW 216, and C850D single drum rollers across multiple generations, including padfoot, high-compaction, DHC, PDHC, and 4i variants
- Restores Full Cab Climate Performance — a cracked or leaking AC hose causes refrigerant loss, compressor strain, and loss of operator cab cooling; this assembly returns the system to its designed operating pressure and airflow output
- Correct Part Number Traceability — part number 05551712 is the Bomag OEM reference for this assembly, eliminating substitution errors during maintenance or rebuild work on covered machines
An AC hose assembly carries pressurized refrigerant between the key components of the cab air conditioning system — typically the compressor, condenser, and evaporator. On single drum rollers operating in warm conditions, the cab cooling system is essential for operator comfort and sustained productivity. When this hose degrades, develops cracks, or the fittings corrode, refrigerant escapes, system pressure drops, and the compressor runs unloaded — eventually leading to compressor damage if not addressed. Replacing the hose assembly with the correct OEM part restores a sealed, pressure-rated circuit and protects the rest of the AC system from secondary wear.
