The Bomag 57100201 Reducer is a genuine OEM component designed for Bomag BC-series refuse/landfill compactors and soil compactors, including the BC 601 RB, BC 671 RB, BC 772 RB, BC 772 RS, BC 772 EB-4, and the full range of BC 5xx, BC 6xx, and BC 7xx generation variants listed in the fitment data. As a direct-from-Bomag part, this reducer is manufactured to the same specifications as the original unit installed at the factory, ensuring an exact match to the mounting interfaces, gear ratio, and torque capacity of the application. Sourced through DHS Equipment, part number 57100201 is the correct replacement for operators and fleet managers who need a dependable, drop-in solution across multiple machine generations.
Key Features
- Genuine OEM Gear Reduction Accuracy — manufactured by Bomag to the original torque and ratio specifications, ensuring the drivetrain delivers the correct output speed and force the machine was engineered for
- Direct-Fit Replacement — machined to match OEM mounting dimensions and interface geometry, so this reducer installs directly into the original housing without modification
- Broad BC-Series Coverage — fits BC 601 RS, BC 601 RB, BC 570 RB, BC 571 RB, BC 572 RB-2, BC 670 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 672 RB-2, BC 672 RB-3, BC 672 RB-4, BC 672 EB-2, BC 771 RB, BC 771 RS, BC 772 RB, BC 772 RB-2, BC 772 RB-3, BC 772 RB-4, BC 772 RS, BC 772 RS-2, BC 772 RS-3, BC 772 RS-4, BC 772 EB-2, and BC 772 EB-4 refuse/landfill compactors and soil compactors
- Sustained Drive Performance — a worn or failed reducer causes loss of ground speed control, uneven compaction force, and accelerated wear on connected drivetrain components; this replacement restores full, consistent power transmission
- Multi-Generation Compatibility — covers original-generation through -4 generation BC-series machines, making this a practical stocking part for mixed fleets and high-utilization landfill operations
A reducer is a gearbox assembly that steps down the high rotational speed of the engine or hydraulic motor to a lower output speed while multiplying torque, allowing the machine's drive wheels or drum to apply the high force needed for effective compaction. On heavy compactors like the BC-series, the reducer is a critical link in the drivetrain — it must handle sustained shock loads, heat, and continuous cyclic stress across long operating shifts. When a reducer wears or fails, the machine loses tractive effort or drive consistency, which directly affects compaction output and can lead to broader drivetrain damage if the unit continues operating.
