The Bomag 05550413 Hose Assembly AC WN3111 is a genuine OEM component designed for Bomag BW 120 AD, BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, and BW 120 AC-4 tandem rollers. Sourced directly from Bomag, this assembly delivers the exact routing, end fittings, and pressure rating specified for these machines. This hose assembly is a direct OEM replacement, ensuring correct installation without adapting or modifying the surrounding system. If your tandem roller is showing signs of a deteriorating or leaking hose line, replacing it with part number 05550413 restores the circuit to its original operating condition.
Key Features
- OEM-Spec Construction — built to Bomag's exact pressure tolerance, hose diameter, and end-fitting configuration for this AC/WN3111 circuit, eliminating the guesswork of generic hose substitutions
- Drop-In Replacement — end fittings and hose length match the original routing on BW 100 and BW 120 series tandem rollers, so the assembly seats correctly the first time
- Broad Tandem Roller Coverage — fits the BW 120 AD, BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, and BW 120 AC-4, covering multiple drive and drum variants within the BW 100 and BW 120 series
- Fluid Circuit Integrity — a sound hose assembly maintains consistent flow and pressure in the hydraulic or accessory circuit it serves, keeping roller output stable and predictable across the drum
- Genuine Bomag Part — supplied as authentic OEM under part number 05550413, traceable to Bomag's own parts catalog for confident ordering and documentation
A hose assembly connects two points in a pressurized fluid circuit — hydraulic, cooling, or accessory — and is engineered to handle the specific pressure, temperature, and bend radius of its installed position. On Bomag tandem rollers, a failed or degraded hose can cause fluid loss, pressure drop, or contamination that directly affects drum drive performance, vibration system output, or climate system function depending on which circuit the hose serves. Replacing a worn hose assembly promptly with the correct OEM part prevents escalating damage to pumps, valves, and other downstream components.
