The Bomag 05903973 Coupling Flange is a genuine OEM component designed for BC 1172 RB-3 and BC 972 RB-3 refuse and landfill compactors. Sourced directly from Bomag, this coupling flange meets the exact specifications of the original part it replaces, ensuring a correct, secure connection within the drivetrain assembly. This part is confirmed to fit the BC 1172 RB-3 and BC 972 RB-3 — two of Bomag's high-output refuse compactor models — giving operators confidence that the right component is going back on the machine.
Key Features
- Genuine OEM Integrity — manufactured to Bomag's exact dimensional and material tolerances for coupling flanges, ensuring proper torque transfer without slippage or fatigue at the joint
- Direct Replacement Fit — matches the original mounting interface and bolt pattern, dropping into place on the BC 1172 RB-3 and BC 972 RB-3 without rework or adaptation
- Confirmed Compactor Fitment — verified for Bomag BC 1172 RB-3 and BC 972 RB-3 refuse and landfill compactors, so you can order with confidence
- Drivetrain Power Transmission — a sound coupling flange maintains the rigid, aligned connection between drivetrain components; a worn or damaged flange leads to vibration, misalignment, and accelerated wear on adjacent parts
- Authorized OEM Sourcing — carrying genuine Bomag part number 05903973 means you get the manufacturer-approved component, not an approximation
A coupling flange is a precision-machined connector that joins two rotating shafts or drivetrain components, transmitting torque while maintaining precise alignment between them. On heavy refuse and landfill compactors like the BC 1172 RB-3 and BC 972 RB-3, where the drivetrain endures extreme stress from continuous compaction cycles over rough terrain, a properly functioning coupling flange is critical to smooth, efficient power delivery. When this component cracks, wears, or loosens, the result is vibration, drivetrain noise, and eventual damage to connected shafts and bearings — making prompt replacement with the correct OEM part essential to keeping the machine productive.
