The Bomag 05540999 Reducing Block is a genuine OEM component designed for BC-series refuse/landfill compactors and soil compactors, including the BC 671 RS, BC 771 RS, BC 772 RS, BC 772 RS-2, BC 772 RB-2, BC 772 RB-3, BC 672 RB-2, and BC 772 EB-2. Sourced directly from Bomag, this reducing block carries the exact dimensions and material specifications of the original, ensuring a proper fit without adaptation. Whether you are servicing a high-cycle landfill compactor or a heavy-duty soil compactor, this part delivers the correct interface geometry your machine was built around.
Key Features
- Genuine OEM Precision — manufactured to Bomag's original tolerances, ensuring the reducing block seats correctly and maintains the structural integrity of the hydraulic or mechanical connection it serves
- Direct Replacement Fit — matches the original part number 05540999 exactly, dropping into place on compatible BC-series machines without rework or shimming
- Broad BC-Series Coverage — fits BC 671 RS, BC 771 RS, BC 772 RS, BC 772 RS-2, BC 772 RB-2, BC 772 RB-3, BC 672 RB-2, and BC 772 EB-2 refuse/landfill compactors and soil compactors
- Maintains System Alignment — a correctly sized reducing block preserves proper load transfer and fluid or mechanical passage alignment; a worn or incorrect block risks misalignment, leaks, or accelerated wear on adjoining components
- Authentic Bomag Quality — genuine OEM sourcing means the alloy grade, thread pitch, and bore sizing all match what Bomag specified for these heavy-duty compaction machines
A reducing block is a transitional fitting or adapter that bridges two components of differing size, thread, or bore diameter within a hydraulic, mechanical, or structural assembly. On heavy compactors like the BC-series, it ensures that lines, fittings, or structural members connect correctly and maintain the load-bearing or fluid-carrying capacity the system requires. When a reducing block wears, cracks, or is replaced with an incorrectly sized substitute, the result can be fluid leaks, pressure loss, structural misalignment, or damage to the connected components — making it a small but critical part in keeping the machine operating as designed.
