Bomag 05541513 Eccentric Banjo Coupling

The Bomag 05541513 Eccentric Banjo Coupling is a genuine OEM hydraulic fitting designed for a wide range of Bomag tandem rollers, single drum rollers, cold milling machines, recyclers/stabilizers, and trench compactors. As a direct-sourced OEM component, this coupling is manufactured to the same specifications as the original part it replaces, ensuring a correct, leak-free connection in the hydraulic circuit. This part fits an extensive lineup including BW 120 AD, BW 174 AD, BW 213 DH-4, BM 500/15, BM 600/15, MPH 122, and BW 850 T models, among many others. Confirm your machine's model against the full fitment list before ordering to ensure compatibility.

Key Features

• Genuine OEM Hydraulic Integrity — manufactured to Bomag's original specifications for correct thread engagement, sealing surface geometry, and eccentric offset — critical qualities in a banjo-style hydraulic coupling where even minor dimensional variance causes leaks
• Drop-In Hydraulic Line Replacement — the eccentric design aligns the banjo bolt port to match the original hydraulic line routing, allowing the fitting to seat and torque correctly without rerouting hoses or modifying the hydraulic assembly
• Broad Cross-Family Coverage — fits Bomag BW-series tandem rollers, BW-series single drum rollers, BM-series cold milling machines, MPH-series recyclers/stabilizers, and BW-series trench compactors, spanning multiple generation variants including -2, -4, -40, -50, and Stage V machines
• Leak-Free Hydraulic Circuit Performance — a properly functioning eccentric banjo coupling maintains full system pressure and flow; a cracked, cross-threaded, or worn original fitting causes hydraulic fluid loss, pressure drop, and potential damage to downstream components
• Verified Part Number Traceability — part number 05541513 corresponds directly to Bomag's OEM catalog entry, so you can cross-reference your machine's service documentation with confidence before installation

An eccentric banjo coupling is a specialized hydraulic fitting that connects a hydraulic line to a port on the machine using a hollow bolt passing through a swiveling banjo eye. The eccentric offset built into this coupling allows the fluid passage to be positioned at a specific angle relative to the bolt centerline, accommodating tight hose routing in confined hydraulic assemblies without bending or stressing the line. When this fitting cracks, strips, or develops a compromised sealing surface, the hydraulic circuit loses pressure integrity — resulting in external fluid leaks, reduced actuator or motor performance, and potential contamination of surrounding components. Replacing a damaged coupling promptly with a correct OEM part restores sealed, full-pressure operation.
