The Bomag 05613185 Elastic Coupling Ring is a genuine OEM component designed for BC-series refuse and landfill compactors, MPH-series recyclers/stabilizers, and the BC 473 EB-3 soil compactor. Sourced directly from Bomag, this coupling ring meets the exact tolerances and material specifications of the original part. It is confirmed to fit the BC 601 RB, BC 601 RS, BC 571 RB, BC 572 RB-2, BC 671 RB, BC 671 RS, BC 672 RB, BC 771 RB, BC 771 RS, BC 473 RB-3, BC 473 EB-3, MPH 121, MPH 122, and MPH 122-2, making it a versatile OEM solution across several heavy compaction and stabilization platforms.
Key Features
- Genuine OEM Flexibility Rating — manufactured to Bomag's original elastomer specification, delivering the correct torsional dampening and flex characteristics this coupling demands
- Direct Drop-In Replacement — matches the original mounting geometry and ring dimensions, so this part seats correctly without rework or shimming
- Broad Fleet Coverage — fits BC 601 RB, BC 601 RS, BC 671 RB, BC 671 RS, BC 672 RB, BC 771 RB, BC 771 RS, BC 571 RB, BC 572 RB-2, BC 473 RB-3, BC 473 EB-3, MPH 121, MPH 122, and MPH 122-2
- Drivetrain Shock Absorption — a healthy elastic coupling ring smooths torque spikes between the engine and drivetrain; a cracked or hardened ring transmits shock loads that accelerate wear on connected components
- Drivetrain Protection — maintaining this ring in good condition shields pumps, gearboxes, and shafts from torsional stress, preserving the integrity of the wider powertrain
The elastic coupling ring sits between the engine output and the hydraulic or mechanical drivetrain, acting as a flexible buffer that absorbs vibration and torsional shock generated during heavy compaction cycles. By flexing under load, it protects downstream components — pumps, gearboxes, and drive shafts — from damaging torque spikes that would otherwise cause premature wear or failure. When the ring cracks, hardens, or deteriorates, those shock loads pass directly through the drivetrain, often resulting in accelerated bearing wear, coupling damage, and costly secondary repairs.
