The Bomag 05557628 AC Hose Assembly WN3111 is a genuine OEM air conditioning hose assembly designed for BMP 8500 trench compactors, including the BMP 8500, BMP 8500 Kohler, and BMP 8500 Kubota variants. Sourced directly from Bomag, this assembly delivers an exact match to the original routing, fittings, and line specifications for the BMP 8500 platform. Installation is straightforward — this assembly connects directly into the existing AC circuit without rework or adaptation. Operators running any BMP 8500 variant can order with confidence knowing this is the correct OEM-specified hose for their machine.
Key Features
- Genuine OEM AC Line Integrity — manufactured to Bomag's original pressure rating and hose construction spec, ensuring the AC circuit maintains proper refrigerant containment and flow characteristics
- Exact Routing and Fitting Match — this assembly replicates the original end fittings, hose length, and bend geometry so it seats correctly in the BMP 8500 AC system without cutting or re-flaring
- Full BMP 8500 Platform Coverage — fits the BMP 8500, BMP 8500 Kohler, and BMP 8500 Kubota trench compactors, covering all engine variants in the BMP 8500 family
- Prevents Refrigerant Loss and Compressor Damage — a cracked or degraded AC hose leads to refrigerant leaks, loss of cab cooling, and potential compressor seizure; replacing with a correctly rated OEM assembly restores the sealed circuit
- Verified by Part Number 05557628 — cross-reference part number 05557628 against your BMP 8500 parts manual to confirm application before ordering
The AC Hose Assembly WN3111 is a pressurized refrigerant line within the machine's air conditioning circuit, responsible for carrying refrigerant between major AC components such as the compressor, condenser, and evaporator. A functioning hose assembly maintains the sealed pressure environment that allows the system to cool the operator cab effectively. When this hose develops cracks, fitting corrosion, or line fatigue — common in demanding compaction environments — refrigerant escapes, cooling performance drops rapidly, and the compressor can be damaged by running without adequate lubrication carried in the refrigerant flow.
