Key Features

• Genuine Bomag OEM Construction — manufactured to the same material and dimensional standards as the original loop ring installed at the factory, maintaining the integrity of the retention or sealing function this ring performs in service
• Direct OEM Replacement — part number 05578104 matches the factory bill of materials for covered machines, so this loop ring seats and secures exactly as the original did without rework or adaptation
• Broad Cross-Family Coverage — fits BC-series refuse/landfill compactors (including the BC 601 RB, BC 601 RS, BC 570 RB, BC 571 RB, BC 670 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 771 RB, and BC 771 RS) and BW-series tandem rollers (including the BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 170 AD, BW 174 AC, BW 174 AC AM, BW 174 AD, BW 174 AD AM, BW 202 AD-2, and BW 202 AHD-2)
• Structural Retention Integrity — a correctly fitted loop ring keeps connected components properly anchored and aligned; a worn or damaged ring can allow unwanted movement, vibration, or fluid path disruption that compounds into larger drivetrain or hydraulic issues
• Traceability You Can Count On — ordering by genuine Bomag part number 05578104 gives you a clear service record and confirms the correct part was used, supporting accurate maintenance documentation for your fleet

A loop ring is a formed retention component used to secure, anchor, or seat adjoining parts within an assembly — commonly found in hydraulic circuits, drivetrain linkages, or structural connection points. It prevents lateral movement or separation between mating components, ensuring the assembly maintains correct alignment and load transfer under the high-stress, high-vibration conditions typical of landfill compactors and tandem asphalt rollers. When a loop ring becomes worn, deformed, or broken, the connection it maintains can loosen, leading to accelerated wear on surrounding components or a loss of hydraulic or mechanical function in the affected system.
