The Bomag 05541445 Eccentric Banjo Coupling is a genuine OEM component designed for Bomag BW-series tandem rollers, including the BW 135 AD, BW 170 AD-2 AM, BW 170 AP AM, BW 174 AD-2, BW 174 AD-2 AM, BW 174 AC-2, BW 174 AC-2 AM, BW 174 AP, BW 174 AP-AM, BW 174 ACP, BW 174 ACP-AM, and BW 184 AD-2 AM. Sourced directly from Bomag, this coupling carries the exact geometry and thread specification of the original, ensuring a drop-in hydraulic connection without improvisation or rework. Contractors running any of the covered BW tandem rollers can order with confidence, knowing part number 05541445 is the same component that left the factory.
Key Features
- OEM Hydraulic Precision — manufactured to Bomag's original port geometry and thread tolerances, so sealing surfaces mate correctly and the eccentric offset aligns as intended in the hydraulic circuit
- Direct Hydraulic Connection — the eccentric banjo design accommodates angled line routing without bending or stressing hoses, installing directly in place of the original coupling on all covered models
- Broad BW Tandem Roller Coverage — a single part number 05541445 fits the BW 135 AD, BW 174 and BW 170 series variants, and the BW 184 AD-2 AM, covering a wide spread of Bomag tandem roller configurations
- Leak-Free Hydraulic Integrity — a correctly fitted eccentric banjo coupling maintains system pressure and flow; a worn or cross-threaded coupling risks hydraulic fluid loss, erratic drum drive, and unplanned machine downtime
- Fuel and Fluid System Safety — proper torque and sealing at every banjo connection is critical to safe hydraulic system operation; using the correct OEM coupling eliminates the risk of mismatched fittings that can fail under working pressure
A banjo coupling is a hydraulic fitting that allows a fluid line to connect at an angle to a port, using a hollow bolt and a drilled spherical fitting to pass fluid through the joint. The eccentric version offsets the bolt centerline from the banjo centerline, giving technicians precise control over hose routing in tight or awkward spaces — a common requirement in the compact hydraulic circuits of tandem asphalt rollers. When this fitting cracks, strips, or develops a leak, hydraulic pressure drops and drum drive or vibration circuits can behave erratically, interrupting compaction work until the fitting is replaced.
